Abstract
A process for carrying out a chemical equilibrium reaction is disclosed in which, in a first stage, one or more reactants are contacted with a fixed arrangement of a catalyst under conditions such that the reactants and the products of the reaction are gaseous, the unconverted reactants and products of the first stage being passed to a second stage, in which they are contacted with a fixed arrangement of a catalyst and the reaction allowed to proceed in the presence of an absorbent capable of absorbing a product of the reaction. There is specifically disclosed a process for the synthesis of methanol from carbon monoxide and hydrogen, in which, in a first stage, carbon monoxide and hydrogen are contacted with a fixed arrangement of a catalyst active in catalyzing the synthesis of methanol under conditions such that the methanol formed is present as a gas under the prevailing reaction conditions, the unconverted carbon monoxide and hydrogen and methanol produced in the first stage being passed to a second stage, in which they are contacted with a fixed arrangement of a catalyst active in catalyzing the synthesis of methanol and the reaction allowed to proceed in the presence of an absorbent capable of absorbing methanol.
