Photocatalytic synthesis ammonia reactor and photocatalytic synthesis ammonia reaction system

Abstract

The invention discloses a photocatalytic synthesis ammonia reactor and a reaction system. The photocatalytic synthesis ammonia reactor comprises a substrate, a catalytic layer and a fixed frame which are sequentially overlapped and fixed, the side, close to the catalyst layer, of the base plate is provided with a flow channel, and the front side face and the rear side face of the base plate are provided with an air inlet and an air outlet which communicate with the flow channel correspondingly; a light-transmitting layer is hermetically mounted on the side surface, far away from the catalyst layer, of the fixed frame, the light-transmitting layer, the catalyst layer and the fixed frame form a liquid flow space, and a water inlet and a water outlet which are communicated with the liquid flow space are formed in the fixed frame; a plurality of through holes communicated with the flow channel and the liquid flow space are formed in the catalytic layer, and a photocatalyst is arranged on the catalytic layer; a plurality of grooves extending in the vertical direction are continuously and evenly formed in the side, close to the catalyst layer, of the base plate, and the grooves are sequentially communicated and communicated with the air inlet and the air outlet to form the flow channel. The retention time of nitrogen in the reactor can be prolonged, and the conversion efficiency of synthetic ammonia is improved.

Description

technical field [0001] The invention relates to the technical field of photocatalytic electrolysis, in particular to a photocatalytic ammonia synthesis reactor and a photocatalytic ammonia synthesis reaction system. Background technique [0002] Ammonia is one of the most abundant inorganic compounds in the world. Most of it is used as a fertilizer. It is very important to life on earth and is the basis for the development of modern agriculture. Ammonia can be used as a refrigerant, and it is also an important raw material for the manufacture of nitric acid, fertilizers and explosives, and has a wide range of uses. In recent years, under the background of global "carbon peaking and carbon neutrality" development, ammonia, as a zero-carbon carrier, plays a similar role as hydrogen. It can be used as a fuel or raw material to play a role in decarbonization in various economic sectors, and has the potential to be used as a large-scale clean energy source. Compared with hydroge...
