REACTOR AND PRESSURIZED EXOTHERMAL GAS PHASE CATALYTIC SYNTHESIS PROCESS

摘要

1. Cylindrical and horizontal reactor for pressurised exothermal single-layer gas-phase catalytic synthesis, characterised in that it is formed by a main casing under high pressure or a force-resistant member, composed of a cylindrical part (1) and of two hemispherical end members (2) (2'), containing a catalyst-supporting chamber (10, 11, 11') carrying a single layer or bed of catalyst (9, 9', 9"), concentric with the force-resistant member and of which the external wall is lined with an insulating material (39), a space (31, 32, 33, 34) being formed between the internal wall of the force-resistant member and that of the external wall of the insulator-lined catalyst-supporting chamber, resting on hoops and on a helical metallic winding (40) from one end to the other of the casing, the main casing under high pressure and the catalyst-supporting chamber being provided with introduction means (3) and (5) and discharge means (3') and (5') for the gaseous flows, situated at the ends of the main axis and disposed facing one another on the hemispherical end members, the catalyst-carrying chamber also being equipped with a vertical socket (13) for the charging with emptying of the catalyst.
