Decarboxylation and further transformation of oleic acid over bifunctional, Pt/SAPO-11 catalyst and Pt/chloride Al2O3 catalysts

Catalytic decarboxylation and further conversion of oleic acid to branched and aromatic hydrocarbons in a single process step, over Pt-SAPO-11 and Pt/chloride Al2O3 is presented. An increase of both reaction time and temperature increase the selectivity to heptadecane. Higher selectivity to heptadecane was observed in the presence of hydrogen. Decarboxylation of oleic acid was as high as similar to 98 wt% (selectivity for heptadecane > 30%) at 325 degrees C in the presence of hydrogen. Branched isomers, alkyl aromatics, like dodecyl benzene and cracked (< C-17) paraffins were the other products. (C) 2014 Elsevier B.V. All rights reserved.
