Abstract
Official abstract text for this publication.
A method for the epoxidation of an olefin comprising the steps of reacting a feed gas composition containing an olefin, oxygen, and a moderator having a post-conditioning step where the catalyst is exposed to reactor feed having a chlorides concentration of from about 5 ppm to about 7 ppm and at a temperature of about 215° C. to about 225° C.
First claim
Opening claim text (preview).
We claim: 1. A method for the epoxidation of an olefin comprising: initiating an epoxidation reaction by reacting a feed gas composition containing ethylene, oxygen, and a chloride moderator present at a concentration of from about 0.5 ppm to about 3 ppm, in the presence of an epoxidation catalyst at a temperature of about 245° C. to about 265° C.; increasing the moderator concentration to about 5 ppm to about 7 ppm and lowering the temperature to about 215° C. to about 225° C.;…
