Microchannel reactor applicable to dehydrogenation reaction of liquid hydrogen source materials and dehydrogenation method

Abstract

The invention discloses a microchannel reactor applicable to dehydrogenation reaction of liquid hydrogen source materials and a dehydrogenation method. Flow guide plates are arranged in a liquid distributor which is connected above a microchannel reactor body, a high-temperature flange is arranged between the liquid distributor and a hydrogen source material inlet, the lower portion of the microchannel reactor body is provided with a hydrogen storage carrier and hydrogen outlet, and a high-temperature flange is arranged between the microchannel reactor body and the outlet. A heat carrier distributor is connected to an inlet side of the microchannel reactor body, flow guide plates are arranged in the heat carrier distributor, a high-temperature flange is arranged between the heat carrier distributor and a heat carrier inlet, the other side of the microchannel reactor body is provided with a heat carrier outlet, and a high-temperature flange is arranged between the microchannel reactor body and the heat carrier outlet. The microchannel reactor body is internally provided with a plurality of transverse and longitudinal orthogonal microchannels. By the microchannel reactor, reaction efficiency is improved, and reactor cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage, in particular to a microchannel reactor suitable for the dehydrogenation reaction of liquid hydrogen source materials and a dehydrogenation method.
