Problems solved by technology

The formation of hot spots (or conversely, cold spots) can lead to a reduction in the efficiency of tube-cooled reactors and potentially lead to undesired side reactions at the points furthest from the tubes

Abstract

A reactor (1) for thermochemical reactions is provided comprising a reactor shell (13) having an inlet (2) and an outlet (3). Solid catalyst (16) is provided in reaction zones (4a, 4b, 4c) in which atleast a portion of reactants entering the reactor (1) undergo a thermochemical reaction. A heat exchange medium is provided in heat exchange zones such that heat is exchanged between the reaction zones (4a, 4b, 4c) and the heat exchange medium. One or more hollow inserts (11) at least partially extend through the reaction zones (4a, 4b, 4c). The hollow inserts (11) are configured to form a flow path to either: divert a portion of the reactants from the reactor inlet (2) or from one reaction zone to a different reaction zone; or divert a portion of the heat exchange medium from one heat exchange zone to a different heat exchange zone.

Description

technical field [0001] The present disclosure relates to catalytic reactors, and more particularly to catalytic reactors for thermochemical reactions. More specifically, the present disclosure relates to apparatus and methods for reducing temperature variation and improving the performance of reactors conducting thermochemical reactions. Background technique [0002] Catalytic reactions involve the conversion of one or more reactants to one or more desired products in the presence of a catalyst, such as a reaction between carbon monoxide and hydrogen in the presence of a Cu / ZnO catalyst to produce methanol. Many catalytic reactions are thermochemical reactions, ie: exothermic reactions, in which heat is released during the reaction process, or endothermic reactions, in which heat is absorbed during the reaction process. However, some catalytic reactions are also highly temperature-dependent, operating efficiently only within a narrow temperature range. [0003] Due to the ...
