Thermal catalytic cracking of buriti oil (Mauritia flexuosa L.) over LaSBA-15 mesoporous materials

Reaction pathway analysis in thermal cracking of waste cooking oil to hydrocarbons based on monomolecular lumped kinetics

“…(14)- (16) revealed that all apparent kinetic constants were monotonically increasing with rise in temperature as a result of Arrhenius kinetic law considered in the model. The parity diagram obtained from parameter optimization is illustrated in Fig.…”

“…Triolein was selected as a model component for kinetic analysis as a result of abundantly present in all vegetable oils [6,7]. The plausible free radical reaction chemistry for thermal cracking of triolein was formulated based on information available elsewhere [10,12,16,[20][21][22][23]. The breaking of CAO bonds present at the backbone of triolein is the possible reaction for producing acrolein, long-chain unsaturated fatty acids and unsaturated C 18 ketenes radicals.…”

“…In the literature, kinetic experiments were performed for thermal cracking of vegetable oils such as canola [10][11][12][13], soybean [13,14], rapeseed [15], and buriti [16] oils. In addition, thermal cracking of Calotropis procera biocrude [17], oleic acid [18], abietic acid and tall oil fatty acids [19] was also studied.…”

“…In addition, thermal cracking of Calotropis procera biocrude [17], oleic acid [18], abietic acid and tall oil fatty acids [19] was also studied. The free radical chemistry for thermal cracking of triglycerides to hydrocarbons was proposed by several researchers [10,12,16,[20][21][22][23]. The plausible free radical reactions considered are breaking of CAO bonds present at the backbone of the triglycerides followed by decarbonylation, decarboxylation, ketene elimination, b-scission, alkylation, cyclization, aromatization and so on.…”

Production of ethylene glycol from direct catalytic conversion of cellulose over a binary catalyst of metal-loaded modified SBA-15 and phosphotungstic acid

“…Among all the modication methods, the impregnation method has remarkable advantages such as simple preparation and easier industrial application. 19 Up to now, metals, including Ni, 20 La, 21 Al, 22 Ca 23 and Mg, 24 modied with SBA-15 have shown good catalytic performance in the catalytic cracking of vegetable oils. It is worth mentioning that these catalysts were all prepared using the impregnation method.…”
