PSEUDODIABATIC REACTOR FOR EXOTHERMAL CATALYTIC CONVERSIONS

摘要

A multitubular catalytic reactor for exothermal catalytic reactions comprises a bundle of parallel tubes all of the same length and a catalyst within the tubes. The tube bundle has an inlet side and an outlet side. Devices are provided for introducing separately reactants to within the tubes of the reactor and coolant to the channels defined between adjacent tubes of the bundle. The coolant is introduced into the channels co-currently with the direction of flow of the reactants. The products are withdrawn from the tubes independently of the coolant. The reactor is particularly adapted to a single stage conversion of methanol into gasoline boiling point range constituents using crystalline aluminosilicate catalysts.
