Solar energy-driven carbonaceous matter reaction and reaction product photocatalytic method

Abstract

The invention relates to a solar energy-driven carbonaceous matter reaction and reaction product photocatalytic method. After sunlight passes through a beam splitter, a beam of light enters into a photocatalytic chamber, and the other beam of light irradiates into a cavity type light absorbing cavity through a glass cover plate; solid particles enter the light absorbing cavity through a particle inlet, and the solid particles and the inner wall of the light absorbing cavity simultaneously absorb the sunlight to convert the sunlight into heat energy; the high-temperature hot particles and a carbonaceous matter entering the light absorbing cavity through a carbonaceous matter inlet are mixed; meanwhile, the carbonaceous matter receives the radiation energy of the light absorbing cavity, and the carbonaceous matter rises in temperature to react; a reaction gaseous product flows into a reaction product catalytic treatment system, and most reaction gas and unsaturated reaction oil are catalyzed in the photocatalytic chamber and then flow to an oil storage tank to be stored. The solid particles are heated by a visible light band and an infrared band to provide heat for the carbonaceous material reaction; the unsaturated reaction oil in the reaction product is photocatalyzed by a UV band to increase the stability of the unsaturated reaction oil.

Description

technical field [0001] The invention relates to the field of solar thermochemistry, in particular to a method for solar-driven reaction of carbonaceous substances and photocatalysis of reaction products. Background technique [0002] The total global solar radiation is about 1.7×10 17 W, of which my country accounts for about 1% (1.8×10 15 W, equivalent to 1.9 trillion tons of standard coal per year), is 680 times the current total annual energy consumption in my country, and solar energy has huge development potential. However, the energy flow density of solar energy is relatively low, the energy fluctuation is relatively large, and the storage cost is high. If photovoltaic grid-connected power generation is used, the impact on the grid is relatively large. These problems have always affected the further development and utilization of solar energy. The solar thermochemical method is to focus sunlight through concentrators, increase the energy flow density, reduce energy o...
