Photothermal-coupled microchannel hydrogen-producing reaction device based on high-concentration point light source

Abstract

The invention discloses a photothermal-coupled microchannel hydrogen-producing reaction device based on a high-concentration point light source. The device includes the high-concentration point lightsource and the like. During operation of the device, the direction of the high-concentration point light source is vertically downward; a catalyst placing table is placed on the center of the bottom of a reaction chamber and is aligned with the light path of the high-concentration point light source; a catalyst is placed on the catalyst placing table; reactants are added into the reaction chamber;before a reaction, the reaction chamber is purged with an inert gas by using a gas purging channel, then the high-concentration point light source is used for focusing light of different wavelength bands onto the surface of the photothermal catalyst; and after the reaction, a product is collected via a product sampling port and detected. The reaction device of the invention has a small size and is small in the size of each channel, so the point light source can conveniently focus light onto a catalyst carrier, energy flow density is greatly improved, and at the same time, the gathering of strong light carries heat so as to achieve the purpose of producing hydrogen via a photothermal coupled reaction. The photothermal-coupled microchannel hydrogen-producing reaction device of the inventionhas the advantages of simple structure, convenient operation, stable operation, good heat transfer effect, etc.

Description

technical field [0001] The invention belongs to the technical field of new energy preparation, and in particular relates to a light-thermal coupled micro-channel hydrogen production reaction device based on a high-convergence point light source. Background technique [0002] In recent years, the global consumption and utilization are still dominated by traditional fossil energy such as medium, oil and natural gas. Due to the non-renewable nature of these energy forms and the production of a large amount of waste pollutants after use, causing serious environmental damage, based on this whole Many countries in the world, including the United States, Japan, South Korea, etc., have actively started to explore clean energy such as solar energy, wind energy, hydro energy, geothermal energy, and hydrogen energy to replace traditional fossil energy. In recent years, the Chinese government has also taken a lot of measures to promote the development of the hydrogen energy industry. Ho...
