Abstract:
Processes for reducing the amount of a gaseous iodide-containing impurity present in a recycle gas stream used in the production of ethylene oxide, in particular an alkyl iodide impurity, are provided. Processes for producing ethylene oxide, ethylene carbonate and/or ethylene glycol, and associated reaction systems are similarly provided.

Claim (Index 14):
A reaction system for the production of ethylene carbonate and/or ethylene glycol comprising:\n a recycle gas loop fluidly connected to a source of ethylene and oxygen; an epoxidation reactor comprising an epoxidation catalyst, an inlet, and an outlet, wherein the inlet of the epoxidation reactor is fluidly connected to the recycle gas loop;\n an ethylene oxide absorber comprising an iodide-containing carboxylation catalyst, an inlet, and an outlet, wherein the outlet of the epoxidation reactor is fluidly connected to the inlet of the ethylene oxide absorber, the outlet of the ethylene oxide absorber is fluidly connected to the recycle gas loop, and the ethylene oxide absorber is configured to produce a recycle gas stream comprising an alkyl iodide impurity and a fat absorbent stream comprising ethylene carbonate and/or ethylene glycol; and \n a guard bed system comprising an inlet, an outlet, and one or more guard bed vessels comprising a guard bed material, wherein the guard bed material comprises a spherical support material having a diameter of less than 2 mm, and deposited on the spherical support material, silver in an amount of from 2% to 10% by weight, wherein the inlet and the outlet of the guard bed system is fluidly connected to the recycle gas loop, and the guard bed material is configured to remove at least a portion of the alkyl iodide impurity from at least a portion of the recycle gas stream.
