Abstract: A tubular reactor for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert with cup-shaped structures having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.

Abstract: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.
