METHOD FOR TWO-STAGE PRODUCTION OF DIMETHYL ETHER - ENN XINNENG BEIJING TECHNOLOGY

Title:

METHOD FOR TWO-STAGE PRODUCTION OF DIMETHYL ETHER

Document Type and Number:

WIPO Patent Application WO/2010/130214

Kind Code:

A1

Abstract:

Provided is a method for the two-stage production of dimethyl ether, which is characterized in that two reactors filled respectively with separate catalysts having different performances for dimethyl ether are connected in series, greatly increasing methanol conversion per pass. Another characteristic lies in a method for optimizing the reasonable distribution and utilization of the heat of reaction.
