DH-2 CO2 dehydrogenation catalyst
Product Information
The DH-2 dehydrogenation catalysts are CO2 raw material gas dehydrogenation catalysts, which have high dehydrogenation activity, good anti-toxic performance, high mechanical strength, good thermal stability and so on. The comprehensive performance is equivalent to or exceeds the CN-101 catalyst of the American Engelhard on some indicators. It can be completely used as a substitute for CN-101 catalyst in the removal of hydrogen from CO2 raw materials in large and medium-sized fertilizer plants in China, reducing the residual hydrogen content in the exhaust gas to below 50PPM, fundamentally eliminating the risk of hydrogen-oxygen mixed explosion, avoiding explosion danger, and reducing ammonia consumption. It has significant social and economic benefits.
