AB  - Camelina sativa(L.) Crantz is an oilseed crop with favorable potentials for bio-diesel production, such as the high plant yield, high oil content in the seed, high net energy ratio, and low oil production cost. This review paper deals with the present state and perspectives of biodiesel production from camelina oil. First, important issues of camelina seed pretreatment and biodiesel production are reviewed. Emphasis is given to different biodiesel technologies that have been used so far worldwide, the economic assessment of the camelina oil biodiesel (COB) production, the camelina- based biorefineries for the integrated biodiesel production, the COB life cycle analysis, and impact human health and ecosystem. Finally, the perspectives of COB production from the techno- economic and especially genetic engineering points of view are discussed.

AB  - Ova monografija daje opšti pregled proizvodnje i upotrebe lanika kao industrijske sirovine, pre svega, u proizvodnji biogoriva, a zatim i drugih visokovrednih proizvoda. Prvo, opisani su taksonomska klasifikacija, etimologija, poreklo, kvalitet semena, privredni značaj, morfološka, biološka i agronomska svojstva i tehnologija proizvodnje lanika. Zatim je ukratko predstavljeno stanje tehnologije u pogledu iskorišćenja genetičkih resursa lanika za istraživanje strukture i funkcije gena i metaboličkih puteva radi poboljšanja proizvodnje i kvaliteta ulja. Dalje, opisane su tradicionalne i aktuelne upotrebe lanika, uz prikaz mogućnosti njegovog korišćenja u biorafinerijama. U tehnološkom delu, analizirana je upotreba lanika kao energetskog useva u proizvodnji biodizela, mlaznog biogoriva, bioetanola i drugih vrsta biogoriva. U poglavlju koje se bavi proizvodnjom ulja razmatraju se tehnike dobijanja ulja iz semena lanika. Akcenat je stavljen na prethodnu obradu semena, tehnike izdvajanja ulja iz semena, optimizaciju, modelovanje kinetike i termodinamičku analizu procesa ekstrakcije ulja, kao i na sastav i fizičkohemijska svojstva ulja lanika. Nakon toga, kritički se razmatra proizvodnja biodizela od ulja lanika različitim katalitičkim i nekatalitičkim reakcijama transesterifikacije, uz poređenje njihove efikasnosti. Nadalje, razmatraju se fizičkohemijska i  goriva svojstva biodizela kao transportnog goriva i emisije izduvnih gasova pri njegovom sagorevanju u motorima sa unutrašnjim sagorevanjem, samostalno ili u mešavini sa dizel gorivom. U poglavlju koje se bavi proizvodnjom mlaznog biogoriva predstavljene su vrste i svojstva mlaznih goriva i biogoriva, osnovne sirovine za njihovu proizvodnju, aktuelne i tehnologije proizvodnje u razvoju. U posebnom poglavlju opisana je upotreba slame i pogače lanika kao čvrstog goriva, proizvodnja biogoriva pirolizom slame i pogače i katalitičkim krekovanjem ulja lanika. Razmotrena je, takođe, proizvodnja bioetanola u okviru jedne biorafinerije zasnovane na ukupnoj biomasi lanika. Na kraju, ukratko su analizirani tehnoekonomski, ekološki i sociološki aspekti gajenja, prerade i upotrebe lanika. Ova monografija pokazuje da lanik ima značajan potencijal za proizvodnju ne samo biogoriva nego i drugih visokovrednih proizvoda. Ona, takođe, ukazuje na potrebu za istraživanjima koja će biti usmerena ka boljem iskorišćenju ove biljne uljane sirovine za dobijanje biogoriva i širokog spektra proizvoda.
AB  - This monograph provides a general overview of the production and use of the camelina crop as an industrial raw material, first of all, in producing biofuels and other high-value products. First, the botanical classification, etymology, origin, seed quality, economic importance, morphological, biological, and agronomic properties, and technology of camelina production (crop rotation, tillage, plant nutrition, sowing, variety selection, weed, disease, and pest control, harvesting and storage) are described. Camelina has significant agronomic potential and a unique fatty acid composition, but seed yield and oil content must remain the main objectives of breeding to become more competitive compared to other widely distributed and cultivated oil plant species. Then, state-of-the-art regarding utilizing flax's genomic and genetic resources for manipulating genes and metabolic pathways to improve oil production and quality is briefly presented. Furthermore, the traditional and current uses and future refineries based on the integral use of camelina biomass are described. In the technological part, the use of flax as an energy crop in the production of biodiesel, jet biofuels, bioethanol, and other types of biofuels was analyzed. In the chapter dealing with oil production, the techniques of obtaining oil from flax seeds are discussed. Emphasis is placed on camelina seed pretreatment, oil extraction techniques, optimization, kinetics modeling, thermodynamic analysis of the oil extraction process, and composition and physicochemical properties of camelina oil. After that, the production of biodiesel from castor oil by different catalytic and non-catalytic transesterification reactions is critically discussed, with their efficiencies compared. Furthermore, the physicochemical and fuel properties of biodiesel as a transport fuel and the emissions of exhaust gases during its combustion in internal combustion engines, alone or in a mixture with diesel fuel, are considered. In the chapter dealing with jet biofuel production, the types and properties of jet fuels and biofuels, basic raw materials for their production, and current and developing production technologies are indicated. In a separate chapter, the use of straw and oil cake as solid fuel and biofuel production by pyrolysis of straw and cake and catalytic cracking of camelina oil is described. Bioethanol production within a biorefinery based on the total biomass of camelina was also considered. In the end, the techno-economic, ecological, and sociological aspects of camelina cultivation, processing, and use are briefly analyzed. This monograph shows that the camelina plant has a significant potential for the production of not only biofuels but also other highly valuable products. It also indicates the need for research to better utilize this oil raw material for obtaining biofuels and a wide range of products.

AB  - Corn germ oil (CGO) was recovered from the ground corn germ by maceration using n -hexane at the ranges of the temperature and the solvent:germ ratio (SGR) of 20-70 degrees C and 3:1-10:1 mL/g, respectively. The obtained CGO contained mainly the unsaturated fatty acids (87.09 +/- 0.37%) with linoleic and oleic acid as the most abundant while the main saturated fatty acid was palmitic acid. The CGO extraction yield was statistically analyzed, modeled and optimized combining the response surface methodology with the 33 full factorial design with replication. All individual process variables (maceration temperature, SGR and maceration time), the interaction of maceration temperature with SGR and the quadratic terms of maceration temperature and SGR had a statistically significant influence on the CGO yield. For the kinetic modeling of the CGO maceration, three models, namely the phenomenological model, the model that included instantaneous washing and diffusion and the diffusional model, were tested. Although all models successfully described the kinetics of CGO extraction (MRPD values  lt = 2%), the diffusional model was less accurate. The thermodynamic analysis of CGO extraction showed that the extraction process was spontaneous, endothermic and irreversible.

AB  - U radu su prikazani rezultati istraživanja primene semena bele slačice (Sinapis alba L.) kao sirovine za proizvodnju biodizela. Ulje je najpre izolovano iz semena metodom hladnog presovanja i podvrgnuto metanolizi katalizovanoj kalcinisanim negašenim krečom. Cilj rada je bio da se definiše tehnološki postupak za dobijanje biodizela iz semena bele slačice postupkom koji uključuje ekstrakciju ulja iz semena, heterogeno katalizovanu metanolizu ulja i prečišćavanje sirovog biodizela. Karakteristike prečišćenog biodizela su u skladu sa standardom kvaliteta biodizela EN 14214, izuzev sadržaja Ca i Mg, što usmerava dalja istraživanja ka optimizaciji metoda za prečišćavanje sirovog biodizela.
AB  - The paper deals with the use of white mustard (Sinapis alba L.) seeds as a feedstock for the biodiesel production. The oil was recovered from the seeds by cold pressing and subjected to the methanolysis reaction catalyzed by calcined quick lime. The aim of this work was to develop a suitable technology for biodiesel production from white mustard seed using oil extraction followed by heterogeneous catalyzed methanolysis and crude biodiesel purification. The characteristics of the purified biodiesel were in accordance with the biodiesel quality standard EN 14214, except the Ca and Mg content, indicating the need for further investigations towards the optimization of crude biodiesel purification methods.

AB  - The biodiesel production from white mustard (Sinapis alba L.) seed oil (WMSO) by transesterification with methanol over the quicklime powder was investigated in a batch stirred reactor. Two independent first-order models with respect to triacylglycerols (TAGs) or a more complex model that combined the changing mechanism and the first-order rate law with respect to TAGs and fatty acid methyl esters (FAMEs), respectively described successfully the kinetics of this transesterification reaction. Besides that, the response surface methodology coupled with a full factorial design with replication was applied to model and optimize esters content with methanol-to-WMSO molar ratio, catalyst amount and reaction time (X-1, X-2 and X-3, respectively). The analysis of variance indicated that all individual process factors, the interactions X-1-X-2 and X-2-X-3 and the quadratic term X2 2 influenced significantly FAME content at the 95% confidence level. According to the reduced quadratic model, complete conversion could be achieved with the catalyst loading of 9.8%-10% and the methanol-to-WMSO molar ratio in the range between 6.1:1 and 11.6:1 in 50 min. WMSO was transesterified even faster than sunflower oil in the presence of both quicklime and KOH, due to higher total content of unsaturated fatty acids.

AB  - White mustard seed oil (WMSO) was extracted from the ground seed by cold pressing and Soxhlet extraction using n-hexane. A two-step process consisting of cold pressing of white mustard seed (WMS) and extraction of WMSO from press cake (maceration) was also employed to improve the overall WMSO recovery. The main fatty acids of the WMSO were unsaturated oleic, eicosenoic, erucic, linoleic and linolenic acid. The maceration of press cake was modeled on the basis of a 3(3) full factorial design with replication coupled with the response surface methodology. The analysis of variance and the quadratic equation were used for assessing the significance of the influence of solvent-to-cake ratio, extraction temperature and extraction time on WMSO yield and for optimizing the maceration process. All three individual process factors, the interactions of extraction temperature with solvent-to-seed cake ratio and time as well as the quadratic terms of solvent-to-seed cake ratio and extraction time had a statistically significant influence on WMSO yield at the 95% confidence level. The mean relative percentage deviation of +/- 2.3% and the coefficient of determination of 0.923 proved the adequacy of the developed quadratic model for WMSO yield. The predicted and actual WMSO yields under the optimal maceration conditions (70 degrees C, 6.5:1 mL of solvent per g of seed cake and 5 min) were 7.29 and 7.20 +/- 0.13 g/100 g, respectively. With the two-step process, the WMSO yield of 20.48 g/100 g was achieved, which was 99.2% of the WMSO yield obtained by Soxhlet extraction. This indicated that the two-step process could replace the energy- and solvent-intensive Soxhlet extraction of ground WMS. The model of instantaneous washing followed by diffusion described most adequately the kinetics of WMSO extraction from press cake in the applied experimental region. WMSO extraction from WMS press cake was shown to be as spontaneous, irreversible and endothermic.

AB  - The use of low-cost or priceless feedstocks such as byproducts in biodiesel production results in a reduced overall process costs. The present paper reports the use of corn germs and corn cobs as byproducts from corn-based starch production in the biodiesel production by the methanolysis of the oil extracted from corn germs, catalyzed by the ash produced by combustion of corn cobs. The major aim was to optimize the methanol-to-oil molar ratio, catalyst loading, and reaction time in a batch stirred reactor with respect to the content of methyl ester fatty acids (FAME). The statistical modeling and optimization were carried out using a second-order polynomial (quadratic) model developed by the response surface methodology combined with a 33 factorial design with 3 central points. The FAME content was determined by a high-pressure liquid chromatography method. The analysis of variance showed that only the catalyst amount, the reaction time, the catalyst amount interaction with reaction time and all three quadratic terms were the significant model terms with the confidence level of 95 %. The optimum reaction conditions (the catalyst amounts of 19.8 %, the methanol-to-oil molar ratio of 9.4 mol/mol and the reaction time of 31 min) provided the FAME content of 98.1 %, which was in an excellent agreement with the predicted FAME content (98.4 %). Thus, both corn germs and corn cobs may be suitable feedstocks for biodiesel production.
AB  - Upotreba jeftinih ili bezvrednih sirovina, kao što su sporedni proizvodi, u proizvodnji biodizela ima za rezultat smanjene ukupne troškove procesa.
