Abstract:
A method for performing reversible exothermic gas-solid phase catalytic reactions, the method comprising:compressing a gas feed to a predetermined pressure,raising the temperature of said gas feed to the active temperature of a reacting catalyst by heat-exchanging, and subjecting said gas feed to exothermic reaction in a catalyst layer, whereinsaid gas feed is divided substantially into two streams, stream (1) and stream (2), said stream (1) is heated by heat exchanging with the reacted gas exited from a lower adiabatic catalyst layer (k2) of the catalyst layer, said stream (2) enters cold tubes in a cold tube catalyst layer (k1), which is above the catalyst layer (k2), of the catalyst layer and is heated by counter flowing reaction gas around the cold tubes, the heated streams (1) and (2) are mixed and fed into the cold tube catalyst layer (k1) to perform reaction and exchange heat with the stream (2) counter flowed in the cold tubes, and then enters the adiabatic catalyst layer (2) to perform adiabatic reaction.
