Dehydrogenation Catalysts Containing Various Rare Earth Elements (Pt, Pd Active Compositions) For The Purification Of CO2 Feed Gas In Synthetic Urea

Synthetic urea is the process of synthesizing urea under high pressure and temperature using ammonia and carbon dioxide as raw materials. Urea production is based on coal, natural gas and heavy oil as raw materials. The CO2 feed gas for urea synthesis contains a certain amount of CO, H2, CH4, N2 and sulfide, etc. The presence of explosive gases such as H2, CO and CH4 is the biggest safety hazard for urea production. The use of catalytic combustion method to make the hydrogen in the CO2 raw material and the reaction to generate water is an effective measure to prevent the urea plant explosion.

As a supplier of catalysts for the dehydrogenation of carbon dioxide gas for urea synthesis, we offer high quality products with excellent performance and reliability. Our catalysts can withstand harsh operating conditions and provide optimum performance over a long period of time.

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.
