Title:
A PROCESS FOR RECOVERING REGENERATED HEAT DURING THE PRODUCTION OF LOWER OLEFINS FROM METHANOL
Document Type and Number:
WIPO Patent Application WO/2008/025247
Kind Code:
A1
Abstract:
Disclosed is a process for recovering regenerated heat during the production of lower olefins from methanol by using fluidized bed. The process is characterized in that, before contacting with methanol, the regenerated catalysts at high temperature enter a heat absorbing cracking reaction area in which said catalysts contact with hydrocarbons. The cracking reaction of said hydrocarbons absorbs a part of heat carried by the regenerated catalysts in order to reduce the temperature of said catalysts to satisfy the temperature requirement of the methanol conversion.
