Production, and this use of silver content catalyst and this kind of silver content catalyst

摘要

High activity and the high selective silver catalyst which include with 1 kinds or the accelerator above that which it makes support on the appropriate supporting material which possesses the form of the attaching shape cohesion body the silver and depending upon when. Structure of the attaching shape cohesion body relatively small inside diameter (the aperture) is structure of the hollow circular cylinder which it possesses. The aforementioned catalyst is manufactured the attaching section charge which possesses the geometric form of granularity profit, by installing the catalyst component in this. The aforementioned catalyst is useful in epoxidation of ethylene.
