Catalyst tubes for endothermic reaction especially for the production of hydrogen and syngas

摘要

A regenerating catalytic tube including an outside tube (1), whose ends are sealed by a head flange (2) and a bottom (3), and a second tube (6) which is located coaxially within outside tube (1) so that one end thereof is placed near bottom (3) and the other end terminates outside closure flange or plate (2), the hollow space between coaxial tubes (1 and 6) being filled with a catalyst material (5) which is crossed by the material to be processed during the catalytic reaction and comprising a portion capable of being lapped by a heating medium, and a non-heated portion which is capable of a thermal exchange exclusively between the product (flowing in the output line (4)) of the endothermic reaction and the material to be processed (entering through input line (7)), does not contact the heating medium inside the radiative chamber itself.
