“…the more significant difference is the amount of acid in the product, the canola oil is more unsaturated than soybean oil, and this facilitated his deoxygenation, for the least amount of acids in the product. as expected the deoxygenation is facilitated for the unsaturated and polyunsaturated acids (Asomaning et al, 2014a(Asomaning et al, , 2014b.…”

“…under these conditions, it was found that there is no relationship between the degree of saturation of products and the degree of acidity of the catalyst. another important conclusion of this work is that for both catalysts were obtained unsaturated hydrocarbons, usually linear by breaking the double bond in the reactions of DCn and DCX, as found by Asomaning et al (Asomaning et al, 2014a(Asomaning et al, , 2014b. for oleic acid, pyrolysis at 390 °C and 1h of reaction in a batch reactor, with n 2 , generated an amount of 40% of organic acids on the product.…”

“…However in a continuous reactor, with room for the expansion of gases, the hydrogen produced remained in the gas phase, without hydrogenate the oil and, in this way, unsaturation could be fragmented without necessarily the deoxygenation occur, generating more hydrocarbons in gas phase, as predicted by the model molecule tests (Asomaning et al, 2014a).…”

“…On evaluating the chain unsaturation on oleic and linoleic acid deoxygenating pyrolysis (Asomaning et al, 2014a(Asomaning et al, , 2014b, deoxygenation by decarboxylation (DCX) and decarbonylation (DCN) was observed.

“…the author does not address directly dehydrogenation reactions, but it shows a radical formation reactions leading to the formation of cyclic compounds. as triglycerides models with unsaturated fatty acids have not been tested by pyrolysis in a mechanism study, it is a risk to say that the breakdown of triglyceride will be the primary reaction process, without prior fragmentation of unsaturation was been noted when these are present (Asomaning et al, 2014a(Asomaning et al, , 2014b.…”

With the worsening environmental problems caused by the greenhouse effect, the study of fuel alternatives generated by non-fossil sources has intensifi ed. The incorporation of biodiesel (mono-ester of triglycerides) to petroleum diesel is an example of commercial application for reduction in the emission of fossil CO 2 and sOx and nOx as well. in this context, the generation of mixture of hydrocarbons for catalytic cracking of vegetable oils combines the advantages of the Transesterifi cation process to generate compounds such as petroleum-derived fuels such as: gasoline, kerosene and diesel. This review presents current trends in scientifi c literature for biofuels from thermal (pyrolysis) and catalytic processing. For the pyrolysis it has been described the temperatures use to obtain the fuel in the diesel range. the catalytic processing involves the heterogeneous catalysts used in the processing crude oil and the conditions of temperature and pressure. in conclusion it is showed that the cracking catalytic process allows chose what fuel does one want simply changing the catalytic that is used.Keywords: Biofuels, Pyrolysis, Hydroprocessing, vegetable oils.

This study explored the production of aromatic hydrocarbons from the longer-chain alkenes produced by the pyrolysis/cracking of crop oils. 1-Tetradecene, serving as a model compound for these alkenes, was reformed in a batch reactor with a HZSM-5 catalyst to produce a liquid hydrocarbon mixture with a high-aromatic content. These reactions resulted in a >99% conversion of the 1-tetradecene feedstock with a yield of up to 22 wt% of aromatic hydrocarbons. Surprisingly, isomers of C 3substituted benzenes along with xylenes and diaromatics (lower homologs of alkyl-substituted indanes and naphthalenes) were the main aromatic products rather than their lower-molecular-weight (MW) homologs, benzene, toluene, ethylbenzene and xylenes, which are commonly formed with high selectivity during zeolite-catalyzed reforming. The recovery of higher-MW aromatics, and particularly bicyclic naphthalenes and indanes, provides mechanistic insights for zeolite-catalyzed alkene reforming reactions suggesting that these higher-MW aromatics are likely formed near the catalyst surface at pore openings. Furthermore, the production of acyclic diene intermediates in the size range of C 7 -C 10 provides insight into the overall reaction pathway. The results suggest that this reaction pathway may be a commercially viable option for the production of renewable C 3 -substituted aromatic chemicals/ chemical intermediates as coproducts to complement the kerosene and diesel fuel blendstocks that are the primary products from crop oil cracking.
