PCT No. PCT/FR91/00309 Sec. 371 Date Apr. 29, 1993 Sec. 102(e) Date Apr. 29, 1993 PCT Filed Apr. 12, 1991 PCT Pub. No. WO91/16129 PCT Pub. Date Oct. 31, 1991.A tubular pressurized catalytic hydrocarbon converter provided with a cylindrical casing (1) containing vertical gas exhaust pipes (4) around which are arranged reaction tubes (2) which are coaxially placed in sleeves (3). The lower portions of these tubes are connected to the vertical pipes by "pig-tails" and have a novel design since the aim is to increase the converter's reliability and working life by eliminating reaction tube deformation and facilitating "pig-tail" assembly and maintenance. To this end, the converter is provided with a transverse wall attached to the lower ends of the sleeves and provided with openings in which the lower ends of the tubes and vertical pipes are freely inserted. It is also provided with plates (7) having movable covers (8) and attached to the lower ends of the vertical pipes which are in turn connected to the "pig-tails".
