Abstract
Abstract A catalyst for hydrocarbon conversion contains a silica-containing material having a plate or sheet morphology, for example "FU-1" and a material having catalytic activity for hydrocarbon conversion, for example rare-earth exchanged zeolite Y. The catalyst is especially suitable for cracking heavy fractions to naphtha-type products, apparently because the plate or sheet material provides channels by which large molecules can gain access to active centers in the catalyst.
