In the overall process of ammonia synthesis using coal as a raw material, what part does the shift reaction belong to, and what is its principle of operation?

At the outlet of the compression stage, the pressure is generally 0.8 MPa; under the action of the catalyst, CO and H2O react to form CO2 and H2

Some companies are engaged in gas production； Some enterprises are involved in purification ； There are ones that weigh 8 kilograms, 13 kilograms, and also some that weigh over 20 kilograms ； Different companies vary; it depends on how the main processing process is set up and on the configuration of the compressors ； Most of the 8 kilograms come from enterprises that previously produced ammonium bicarbonate as a by-product ； The process principle of the conversion section refers to the reaction of CO with water vapor to produce carbon dioxide and hydrogen. It plays a very important role in the ammonia synthesis process. There are processes that involve a transition from medium pressure to low pressure, processes that go from medium to very low pressure, and also processes that operate at fully low pressure. The reaction equations for carbon monoxide conversion are: (1) CO + H2O = CO2 + H2 + Q and (2) CO + H2 = C + H2O. Reaction (1) is the main reaction, while reaction (2) is a side reaction. In order to ensure that the reaction proceeds in the direction of producing the desired products, industrial applications use catalysts that exhibit good selectivity for reaction (1), thereby suppressing the occurrence of other side reactions. The reaction between carbon monoxide and water vapor is a reversible exothermic reaction, and the heat of reaction is a function of temperature. The transformation process also includes the following reaction equation: H2+O2=H2O+Q

The transformation includes desulfurization and decarbonization.

The conversion stage refers to the process in which CO reacts with water vapor to produce carbon dioxide and hydrogen. After gasification, before purification! ! ! ! ! ! ! ! ! !

Shift belongs to the gas purification process; after gasification and before synthesis, the operating pressure and shift process for shift are generally related to the coal gasification process.
