Title:
A PROCESS OF PRODUCTION OF LOWER OLEFINS AND AROMATICAS
Document Type and Number:
WIPO Patent Application WO2005085391
Kind Code:
A8
Abstract:
A process of production of lower olefins and aromatics involves contacting the feeds with a catalytic pyrolyzing catalyst. There are at least two reaction zones, the temperature of at least one reaction zone in the downstream of the first reaction zone is higher than that of the first one, but the weight space velocity is lower. The oil gas after reaction is separated from the catalyst, and the catalyst is recycled to the reactor after regeneration. The oil gas is separated and the required products of lower olefins and aromatics are obtained. This process can acquire maximum lower olefins such as propylene, ethylene from the heavy feeds, and the yield of the propylene exceeds 20wt. %, at the same time, aromatics such as toluene, xylene is obtained.
