Catalyst LF112A is a kind of low Cr catalyst, which can greatly lessen industrial pollution, tube and container corrosion and harmless to human beings. A certain amount of alkali metal and transition metal are added as the assistant agents. It has the advantages of various high temperature shift catalysts, with good low temperature activity, good heat and sulfur resistance, high mechanical strength and long service time.
