ABSTRACT:
This invention concerns a new carrier catalyst, the active mass of which contains silver, a process for its manufacture and a process for the manufacture of ethylene oxide by reacting oxygen-containing gases with ethylene by using this catalyst. This carrier catalyst comprising a carrier material and a catalyst, the active mass of which is 20 to 90 percent by weight of silver, 0.005 to 5 percent by weight of lithium, and 3 to 70 percent by weight of SiO.sub.2 in free form or in the form of silicates, is extremely well suited for the manufacture of ethylene oxide by adding oxygen to ethylene.
