Abstract
A process for the production of ethylene oxide by the vapor-phase catalytic oxidation of ethylene with molecular oxygen, which process comprises passing a mixed gas containing ethylene and molecular oxygen through a catalyst bed filled with a silver catalyst and subsequently passing the resultant reaction product gas through a cooling zone filled with a particulate material containing a substance capable of inhibiting the isomerization of ethylene oxide to acetaldehyde carrying at least one metal selected from the group consisting of sodium, potassium, rubidium, cesium, calcium, strontium, barium and thallium or a compound of said metal to be carried on an inert refractory particulate material.

A process for the production of ethylene oxide by the vapor-phase catalytic oxidation of ethylene with molecular oxygen, which process comprises passing a mixed gas containing ethylene and molecular oxygen through a catalyst bed filled with a silver catalyst and subsequently passing the resultant reaction product gas through a cooling zone filled with a particulate material having a specific surface area exceeding 0.1 m.sup.2 /g but not exceeding 5 m.sup.2 /g, containing a substance capable of inhibiting the isomerization of ethylene oxide to acetaldehyde containing at least one metal selected from the group consisting of calcium, strontium and barium or a compound of said metal to be carried on an inert refractory particulate material.
