CATALYTIC REACTOR

摘要

A catalytic reactor (1) comprises a housing (2) of heat conducting material in which is located (a) a plurality of catalyst bed tubes (3, 4, 5, 6, 7, 8, 9, 10) interconnected in series and adapted to receive in each catalyst bed tube a through-flowing gas to be catalytically reacted and (b) cooling tubes (34, 35, 36, 37) adapted to receive a through-flowing coolant for controllable extraction of heat from the exothermic reaction. The housing (2) can be a solid cylinder of aluminium or other heat conducting material having the catalyst bed tubes (3, 4, 5, 6, 7, 8, 9, 10) and the cooling tubes (34, 35, 36, 37) drilled lengthwise in the cylinder. The catalytic reaction is particularly suitable for the removal of carbon monoxide from a hydrogen-containing gas by selective catalytic methanation.
