The Thermo-Catalytic Cracking of Hydrocarbons: Effect of Polymethylbenzenes Added to the n-Hexane Feed on the Reactivity of ZSM-5 Zeolite Containing Hybrid Catalyst

Abstract: Hybrid catalyst containing an acidic ZSM-5 zeolite and a Ni bearing co-catalyst, when compared to its reference ZSM-5 catalyst, showed significant differences in terms of conversion and product yields in the thermo-catalytic cracking (TCC) of feeds comprising n-hexane and some 1,2,4-trimethylbenzene (TMB). Almost no difference was observed with the n-hexane feed containing bulkier pentamethylbenzene (PMB). The obtained results were interpreted using two physico-chemical properties of these aromatics and the ca… Show more

“…The configuration of the resulting catalyst extrudates, which does not change during the catalytic reaction and the catalyst decoking, shows high light olefins production and on-stream stability. There has been experimental evidence of the beneficial effect of the cocatalyst whose surface is particularly active in the steam reforming (of methane and other hydrocarbons). It is assumed that hydrogen species, once formed on the cocatalyst surface, can be transferred (spilt over) onto the cracking acid sites of the zeolite particles, thus preventing a rapid activity decay induced by the coke build up.…”
