Abstract

A reaction vessel for hydrogenation of coal or petroleum, or for catalytic synthesis of ammonia has a body 10 of metal or of refractory material with a tightly-fitting, replaceable body-liner 11, e.g. of an alloy of greater coefficient of thermal expansion than that of the body 10, and at one or both ends, a head 12 held in place by a spring-ring 18 and faced by an end-liner 14, <PICT:0659287/III/1> set-screws 40 pressing an end-liner ring 21 against an annular, curved-section, spring sealing-ring 31, square edges of which press against the sides of V-grooves in the ring 21 and a body-liner ring 26. Increased pressure or temperature thus tightens the sealing-ring 31. An outlet 42, with a sealing-ring 44, extends through the head 12, and is welded at 43 to the end-liner 14. In modifications, the sealing-ring 31 is integral with the end-liner ring 21; or the ring 31 is dispensed with, and the end-liner 14 welded to the body-liner ring 26 the two fitting into and being compressed in a V-groove in the head 12; or there is interposed between the end-liner 14 and the bodyliner ring 26, a cylindrical ring welded to both and fitting, with the ring 26 into the V-groove in the head.
