LF92 Low Temperature Sulfur Tolerant Shift Catalyst

Low temperature shift catalyst LF92 can be used either as low temperature shift catalyst or as medium temperature shift catalyst.Specifically when used in medium-low temperature or medium-low-low temperature processes, it can greatly help to reduce ammonia production cost and improve economic benefit. LF92 is mainly used in complete low temperature process, medium-low temperature shift process and medium-low-low temperature process.
