Ammoxidation catalyst containing rare earth elements

Abstract

The invention relates to the field of catalysts, in particular to an ammoxidation catalyst containing rare earth elements. The raw materials are 80-150 parts by weight of titanium dioxide, 35-45 parts of manganese oxide, 2-5 parts of titanium oxide, 10-20 parts of cobalt oxide, 1-3 parts of lanthanum oxide, 1-3 parts of cerium oxide, 3-6 parts of molybdenum, 3-6 parts of vanadium pentoxide. The ammoxidation catalyst containing rare earth elements has strong activity and good catalytic effect under various temperatures and environments.
