A solar methane reforming reaction device and method with uniform heat transfer

Abstract

The invention discloses a solar methane reforming reaction device and method with uniform heat transfer, comprising a methane reforming reactor, the inlet of the methane reforming reactor is connected to a methane gas storage tank and a carbon dioxide gas storage tank, and the methane reforming reactor The outlet of the methane reforming reactor is connected to the synthesis gas storage tank. One side of the methane reforming reactor is provided with a solar simulator for providing heat. sheet, and a fixed-bed catalyst is arranged on the helical twisted guide sheet. In the present invention, a helical twisted flow deflector is arranged in a circular tube reactor, that is, a heating tube, so that the reactant fluid generates a spiral motion in the heating tube, and at the same time, a bionic tree structure heat conduction strip is arranged on the spiral twisted flow deflector, thereby achieving The reaction fluid is evenly heated and fully reacted.

Description

technical field [0001] The invention belongs to the field of solar thermochemical utilization, and in particular relates to a uniform heat transfer solar methane reforming reaction device and method. Background technique [0002] Many reactions in the chemical process are high-temperature endothermic reactions, such as methane reforming, catalytic cracking, thermal cracking and other reactions. The method of burning fossil energy is usually used to provide the energy required for the reaction and keep the reaction temperature constant. However, the burning of fossil fuels will cause environmental pollution and also cause the greenhouse effect. In order to reduce the consumption of fossil fuels, using more renewable energy where possible is an important direction for future energy development. Among many renewable energy sources, solar energy is being gradually popularized and utilized due to its advantages of universality, no pollution, large reserves, and inexhaustibility....
