Abstract

An exothermic catalytic process, particularly methanol synthesis, wherein reactants are passed through a fixed bed (1) of a catalyst and heat evolved by the reaction is transferred to at least part of the reactants fed to the catalyst bed by heat exchange means (2) to which said part of the reactants are fed, characterised by operation of the process under conditions whereby increasing the temperature at which said reactants are fed to the heat exchange means (2) has the effect of decreasing the temperature of which said reactants are heated in said heat exchange means (2), and vice versa, and controlling said process by monitoring the temperature of said reactants leaving said heat exchange means (2) and/or entering said bed (1), decreasing the temperature at which the reactants are fed to said heat exchange means (2) in response to any increase in said monitored temperature, and increasing the temperature at which the reactants are fed to said heat exchange means (2) in response to any decrease in said monitored temperature.
