CO Low Temperature Shift Catalyst
1. CO low temperature shift catalyst modified with promoters, taking copper oxide as active component, zinc oxide as structure promoter;
2. Excellent low-temperature activity and activity stability;
3. Broad activity temperature range, high mechanical strength, low bulk density, long service life.
Product Introduction
CO low temperature shift catalyst used in the shift reaction of CO and steam to form H2 and CO2 under low temperature, widely used in CO low temperature shift process in synthesis ammonia or hydrogen plant. The carbon monoxide (dry gas) in the low-change furnace gas is less than 0.3%, so as to achieve the density of gas purification.

Application Areas:
1. Natural gas to synthetic ammonia, hydrogen production device;
2. Coke oven gas to synthetic ammonia and hydrogen production plant;
3. Catalytic dry gas, coking dry gas to produce synthetic ammonia, hydrogen production device;
4. Oilfield gas, refinery gas, naphtha, etc. as raw materials to produce synthetic ammonia and hydrogen production equipment;
5. CO purification device in coal-based syngas.
Characteristic:
CO low temperature shift catalyst has low loss on ignition, small shrinkage, and the catalyst basically does not sink after reduction;
The active components are well dispersed and the conversion rate is high, and the conversion rate can reach more than 95% under normal process conditions;
For high-sulfur gas devices, the anti-toxic performance is better, and CO low temperature shift catalyst will not cause poisoning and inactivation;
Less additives are added, less by-products, energy saving and consumption reduction.
