Abstract

The invention discloses a gas phase photo-thermal coupling catalytic reactor which comprises an annular cover, a quartz sheet, a reaction bin, a sealing sheet and a heating base; a plurality of through holes are symmetrically formed in the annular cover; the quartz sheet is clamped between the annular cover and the reaction bin; a sealing groove is formed in the top of the reaction bin and is tightly connected with the quartz sheet through a sealing ring; a base is configured inside the reaction bin; and a flow deflector is fixed on the base. A plurality of threaded holes are symmetrically formed in the edge of the reaction bin, and the number of the threaded holes and the position are the same as those of the through holes on the annular cover; and symmetrical vent holes are formed in the side surface of the reaction bin; the heating base is fixedly connected with the reaction bin; and the sealing sheet is positioned between the reaction bin and the heating base. The gas phase photo-thermal coupling catalytic reactor has the beneficial effects that the sealing effect is good, the temperature control precision is high, the retention time of reaction gas in the reactor can be effectively prolonged, and the catalytic efficiency is improved. The gas phase photo-thermal coupling catalytic reactor can be used for symmetrically discussing the effect of temperature on photo-catalytic reaction and can be applied to the exploratory job of a simple relevant reaction mechanism.

Description

technical field [0001] The invention relates to the technical field of photocatalytic reaction, in particular to a gas-phase photothermal coupled catalytic reactor. Background technique [0002] Since Inoue et a1. Titanium dioxide (Ti0 2 ) on photocatalytic reduction of carbon dioxide (C0 2 ) phenomenon, related research has been going on. As global warming worsens and fossil fuel reserves continue to dwindle, using solar energy to reduce C0 2 and water (H 2 0) into methane (CH 4 ) and other available new fuels are of great help to current energy and environmental issues, and are attracting the attention of countries all over the world. [0003] In general, the work in this area is still in the basic research stage, facing the problem of light quantum efficiency and C0 2 Due to the low conversion rate, the details of many reactions occurring on the surface of the photocatalyst are still unclear, especially the factors that affect the reaction have not yet been systema...
