Abstract
A porous solid acid catalyst for producing light olefins is prepared through pillaring and a solid state reaction of a raw material mixture. The catalyst is made of a porous material having a crystalline structure that is different from that of the raw material mixture. The catalyst exhibits excellent catalytic activity (i.e., conversion and selectivity) in the production of light olefins from hydrocarbon feeds such as full range naphthas.
