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

• The catalytic decarboxylation of oleic acid and further conversion of the resulting paraffins over bifunctional catalysts is demonstrated.
• The degree of decarboxylation and selectivity to the primary intermediateheptadecane are affected by temperature, time and environment.
• Higher temperatures, longer reaction times, and the presence of hydrogen increased the degree of decarboxylation and selectivity to heptadecane.
• Significant quantities of hydrocarbons boiling in the gasoline range could also be formed over these bifunctional 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 ∼98 wt% (selectivity for heptadecane >30%) at 325 °C in the presence of hydrogen. Branched isomers, alkyl aromatics, like dodecyl benzene and cracked (
