Methanation catalysts are used in the hydro-methanation process of small amounts of CO and CO2 remaining in the hydrogen-rich gas of ammonia and hydrogen production plants to eliminate carbon oxides and protect ammonia synthesis. The methanation process is currently used in large ammonia plants using natural gas, oilfield gas and light oil as feedstock, as well as in some medium-sized plants using coal as feedstock.
It is mainly used for deep purification to make CO+CO2 ≤ 10 ppm in the gas, with the following main reactivities:
CO+3H2 = CH4+H2O+206.2 kJ/mol
CO2+4H2 = CH4+2H2O+165 kJ/mol
The catalyst has good strength, high activity, good low temperature activity and certain anti-toxic properties. The catalyst is easy to be reduced and has a long service life.
J105 methanation catalyst is a catalyst produced by co-precipitation method with nickel as the active component, rare earths as the accelerator and alumina and magnesium oxide as the carrier. It is a new type of catalyst, combining the advantages of several catalysts currently in common use, with good reductive properties, high activity and heat resistance.
It is used in the ammonia industry to react small amounts of carbon oxides (typically CO+CO2<1.2%) in the synthesis gas with hydrogen to produce water and the inert gas methane to protect the ammonia synthesis catalyst and prevent crystallisation from blocking the system. The product can also be used in other hydrogen production processes to prepare high purity hydrogen.
Methanation Catalyst Working Principle
CO and CO2, at a certain temperature and under the action of the methanation catalyst, react with H2 to produce CH4 and water vapour, which is condensed and separated by rear cooling to give a final qualified hydrogen containing only CH4 impurities. The methanation reaction is a volume-reducing, strongly exothermic process.
