Bifunctional CaCO3/HY Catalyst in the Simultaneous Cracking-Deoxygenation of Palm Oil to Diesel-Range Hydrocarbons

Palm oil is a promising raw material for biofuel production using the simultaneous catalytic mechanism of bifunctional cracking-deoxygenation reactions. Through process, chains palmitic acid and oleic in palm were converted to diesel-range hydrocarbons. The combination effects CaCO3 HY zeolite enhanced into biofuel, because increasing basic sites catalysts due synergistic roles HY. introduction on generated both strong simultaneously designed catalyst, which supports mechanisms hybrid cracking-deoxygenation, respectively. impregnated catalyst has effect supporting reaction as mentioned previously. deoxygenation required CaCO3/HY through decarboxylation, decarbonylation, hydrodeoxygenation mechanisms. Meanwhile, cracking pathway was supported by catalyst. In other words, high acidity strength promotes diesel selectivity, whereas basicity leads reaction.
