A light-thermal coupling microfluidic hydrogen production reaction device based on high-concentration point light source

Abstract

The invention discloses a light-thermal coupling microfluidic hydrogen production reaction device based on a high-concentration point light source, which includes a high-concentration point light source, etc. When working, the direction of the high-concentration point light source is vertically downward; a catalyst placement table is placed at the bottom of the reaction chamber The center is aligned with the optical path of the high-concentration point light source; the catalyst is placed on the catalyst placement table, and the reactant is added inside the reaction chamber. The light source focuses light of different wavelengths on the surface of the photothermal catalyst, and the products after the reaction are collected and detected through the product sampling port. The reaction device of the present invention is small in size, and the size of each flow channel is small, which is convenient for the point light source to gather light on the catalyst carrier, and the energy flux density is greatly improved. At the same time, the gathering of strong light will carry heat, so as to realize the purpose of hydrogen production by photothermal coupling reaction. The invention has the advantages of simple structure, convenient operation, stable operation, good heat transfer effect and the like.

Description

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