| abstract | ABRIDGEMENT An improved process for preparing a silver catalyst which comprises impregnating a porous alumina support with a silver salt, preferably silver nitrate, by contacting a quantity of the support with an aqueous solu-tion of the salt in sufficient amount to be completely absorbed by said support while under a vacuum. A dispers-ing agent is also employed in the aqueous silver salt solution. The support is dried by heating, e.g., 100°C, under vacuum and then, while still under vacuum, impreg-nated with a reducing agent employing an amount suffi-cient to be completely absorbed by the support. Subse-quent heating at a higher temperature, e.g., 250°C, reduces the silver salt to silver metal. A catalyst is produced which, when employed for the oxidation of ethyl-ene, permits the process to run 5°C-10°C cooler at the normal conversion, and also gives an improved yield. 27,422-F -12- |
