Abstract

The invention discloses a hydrogenation reactor. The hydrogenation reactor comprises a reactor cylinder body, wherein the reactor cylinder body is filled with catalyst filler; a liquid inlet, a firstair inlet and a liquid outlet are formed in the reactor cylinder body; a first hydrogen storage alloy container is arranged in the reactor cylinder body and is filled with a hydrogen storage alloy; asecond air inlet and a first air outlet are formed in the first hydrogen storage alloy container, and the second air inlet and the first air outlet extend to the outer part of the reactor cylinder body. Hydrogen storage and heat release are realized by using the hydrogen storage alloy; a hydrogen release and heat absorption principle is that a hydrogenation reactor is used for heating; except thehydrogenation reactor body, the hydrogenation reactor can be heated and refrigerated by only entraining air from a hydrogenation device, so that hydrogenation reaction equipment is simplified; in addition, the required equipment is less, so that the consumption is greatly reduced, and further the cost of the hydrogenation reaction is reduced.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a hydrogenation reactor. Background technique [0002] Hydrogenation reactor is the key equipment of various hydrogenation processes. Hydrogenation is the addition of hydrogen from the outside in the presence of catalysts to increase the hydrogen-carbon ratio of oils and other organic materials, thereby increasing the hydrogenation of oils and other organic materials. the quality of. [0003] The liquid organic material containing benzene ring can undergo addition reaction with hydrogen under the action of high temperature and catalyst, and the addition reaction is an exothermic reaction. Before the reaction starts, the hydrogen and liquid organic materials need to be heated to a certain temperature in the hydrogenation reactor. After the reaction starts, the heat generated can help maintain the temperature of the reactor. In addition, in order to keep the reactio...
