The catalyst is added with a special additive, which is suitable for the new catalyst used in the high CO raw material gas and low water/gas shift process. It has the function of inhibiting the side reaction of methanation, and can exert its Excellent catalyst activity and can inhibit the occurrence of side reactions of methanation.
It is suitable for CO low-temperature shift reaction in synthetic ammonia and hydrogen production plants using natural gas, naphtha, oilfield gas and coal as raw materials. Low bulk density, low weight loss on ignition, low product yield, excellent activity performance above 175 degrees when dry gas is used as the original carrier gas, excellent performance, suitable for low steam-gas ratio operation, and is an energy-saving product.
