PROCESS FOR IMPROVING THE SELECTIVITY OF AN EO CATALYST |
摘要 |
The present invention relates to a process for improving the selectivity of an EO process utilizing a highly selective EO catalyst. In particular, the present invention is an improvement in the initial operation of a process for manufacturing ethylene oxide by contacting ethylene, oxygen, a chloride moderator and a hydrocarbon co-moderator with a high selectivity silver-containing catalyst at a concentration of carbon dioxide of less than about 2 mole percent, wherein the initial operating temperature is determined by optimization of such initial operating temperature at a level higher than the normal low initial operating temperature that is typically selected to obtain a longer operating cycle.
