Abstract

The present disclosure relates to a method for producing propylene D, in particular to methods comprising subjecting a sustainable hydrocarbon feed A to a first catalytic cracking 20 in the presence of a first cracking catalyst comprising a first zeolite, followed by a second catalytic cracking 30 in the presence of a second cracking catalyst comprising a second zeolite. The first and the second zeolite are selected from zeolites of a 10 MR framework type, hierarchical zeolites of a 10 MR framework type and zeolites of a 12 MR framework type, and the second zeolite has a framework type that is different from the first zeolite unless both the first and the second zeolite are hierarchical zeolites of a 10 MR framework type, with the proviso that when the first zeolite is a zeolite of a 10 MR framework type, the second zeolite is a hierarchical zeolite of a 10 MR framework type or a zeolite of a 12 MR framework type.
