LF116 High Temperature Shift Catalyst

LF116 is a kind of low Cr high temperature shift catalyst used in ammonia plant. The Cr content in it is low, much less harmful to workers and environment. This kind of catalyst has good low temperature activity, strong heat resistance, high sulfur resistance, high mechanical strength as well as long operating life. It can be used in atmospheric pressure or pressured shift reaction, with strong suitability.
