Decarboxylation of oleic acid over Pt catalysts supported on small-pore zeolites and hydrotalcite

The catalytic decarboxylation and further conversions of oleic acid to paraffins, branched and aromatic hydrocarbons over Pt supported on small pore zeolites and hydrotalcite are demonstrated. The influence of the support, platinum source, and reaction temperature on the decarboxylation of oleic acid was investigated. An increase in reaction temperature increased the degree of decarboxylation and selectivity to heptadecane. Pt-SAPO-34 was a very effective catalyst. In addition to a high degree of decarboxylation, Pt-SAPO-34 displayed a high selectivity to heptadecane and dodecylbenzene among the products. Branched isomers, cracked (mostly
