Progress of Molybdenum Recovery Process in Spent Hydrogenation Catalyst
The crude oil hydrogenation treatment process consumes a large number of catalysts,and these waste hydrogenation catalysts contain a large amount of molybdenum resources.If directly discarded,it will cause resource waste and environmental pollution.Therefore,it is of great sig-nificance to recycle molybdenum from the waste hydrogenation catalyst.This paper summarizes the technological progress of molybdenum recov-ery by waste hydrogenation catalyst,mainly discusses the fire method,wet method,fire and wet combination method and other processes,and compares the advantages and disadvantages of each process,to provide ideas for subsequent research.
