청구항

A hydrocarbon conversion process comprising: (a) contacting a hydrocarbon feed with a dehydrocyclization catalyst at dehydrocyclization conditions to form a reformate, wherein at least part of said dehydrocyclization catalyst comprises a large-pore zeolite containing at least one Group VIII metal; and (b) contacting said reformate with an intermediate pore size zeolite at a temperature of from 800°F. to 1100°F., an LHSV of from 0.1 to 10, and an H2/HC of from 0 to 6.
