CHROMIUM CATALYST AND CATALYTIC OXIDATION PROCESS

摘要

In accordance with the present invention there is provided a method for making and using an improved chromium catalyst which is useful in oxidation of combustible materials such as hydrocarbons, chloro0carbons, chlorohydrocarbons, polymers and other combustible materials. The process for the catalytic oxidation of combustible material comprises: contacting a combustible material in a heated reaction zone in the presence of oxygen and a chromium impregnated catalyst prepared by impregnating a supporting material with a chromium compound and calcining the solid material at a temperature and for a time at least sufficient for the supporting material to reach a temperature of at least 7250C. By the method, the catalyst exhibits reduced loss of chromium to the environment.
