Abstract

The invention relates to a device and a method for microwave discharge plasma catalytic reforming of greenhouse gas. The device comprises a carbon dioxide bottle and a methane bottle, the carbon dioxide bottle and the methane bottle are respectively communicated with a first cavity through gas tubes, and every gas tube is provided with a flow meter; and the first cavity is communicated with a microwave resonant cavity, the microwave resonant cavity is communicated with a catalytic reforming reactor, the catalytic reforming reactor is a double-layered cylindrical structure, one end of the innerlayer of the catalytic reforming reactor is communicated with the microwave cavity, the outer layer is provided with a water channel, and the water channel and a water tube form a circulation loop. The conversion rate of the plasma catalytic reforming reaction can be calculated according to the gas concentration detected by a sensor, and the reaction temperature in the catalytic reforming reactorcan be changed by using the temperature control in order to realize the adjustment of the conversion rate.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a microwave discharge plasma catalytic reforming greenhouse gas device and method. Background technique [0002] The emission of greenhouse gases such as methane and carbon dioxide will exacerbate global warming and the deterioration of the natural environment. Microwave discharge plasma catalytic reforming technology can simultaneously convert two greenhouse gases, methane and carbon dioxide, into synthesis gas (carbon monoxide and hydrogen), thereby reducing greenhouse gas emissions, and can also generate high value-added hydrocarbons such as ethylene and acetylene, which is of great importance. social and economic benefits. [0003] Microwave discharge plasma is usually excited by a microwave power supply with a frequency of 2.45 GHz, and the energy is transmitted to the microwave resonant cavity through a waveguide or microwave transmission line,...
