Catalytic deoxygenation of stearic acid over palladium supported on acid modified mesoporous silica

Catalytic deoxygenation of stearic acid were investigated over palladium supported on acid modified mesoporous silica SBA15 and MCM-41. Liquid product analysis performed by gas chromatography shows that palladium supported on acid modified SBA15 was active toward deoxygenation product of n-pentadecane with selectivity up to 67% after 5h reaction. Moreover, deoxygenation of stearic acid was also observed during the reaction that confirmed by mass spectroscopy the formation of n-heptadecane
