Dehydrocyclization-cracking of methyl oleate by Pt catalysts supported on a ZnZSM-5-Al₂O₃ hierarchical composite.

ABSTRACT: The dehydrocyclization-cracking of methyl oleate was performed by ZnZSM-5-Al₂O₃ hierarchical composite-supported Pt catalysts in the range of 450-550 °C under 0.5 MPa hydrogen pressure. Most catalysts converted methyl oleate completely and produced aromatics with more than 10 wt% yield as well as valuable fuels even at 450 °C. The reactivity of catalysts changed remarkably depending on the addition method of Pt, while supporting Pt of 0-0.16 wt% did not affect the pore structure of each catalyst. When Pt was introduced into the composite support by the conventional impregnation method, remarkable hydrocracking proceeded through the decarboxylation and decarbonylation of methyl oleate and the successive conversion of C17 fragments and gave the significant amounts of ga
