Embodiment 1

[0040] First, fill 25g of corn stalks into the reaction zone of the dielectric barrier discharge plasma reactor, and feed CO2 at 200ml / min from the gas inlet of the reactor. 2 Gas, connect the external electrode AC power supply, the power supply is 180W, and the discharge frequency is 6500Hz. At this time, CO 2 Reduction reaction, the mixed gas after the reaction includes CO, H 2 O and organic gases and residual CO 2 The gas outlet of the plasma reactor sequentially enters the H 2 O adsorption tank, organic gas adsorption tank, mixed gas CO and CO 2 Separation by pressure swing adsorption device, the product gas CO is pressed into the CO gas storage tank through the compressor, CO 2 After being decomposed by a vacuum pump, it is sent to the gas inlet of the reactor for cyclic reduction. After three cycles, the obtained CO and CO 2 Sampling, tested and analyzed, CO and CO 2 Separation purity is CO 2 greater than 90%; CO greater than 80%, after calculation and analysis, C...

Abstract

The invention provides an apparatus and a method used for reducing CO2 by using dielectric barrier discharge plasma combined with biomass. The invention belongs to the technical field of environmental pollution controlling. The apparatus comprises a plasma reactor. The apparatus also comprises an H2O absorption cylinder, an organic gas absorption cylinder, a pressure swing adsorption apparatus and a CO gas storage cylinder which are orderly connected to the plasma reactor. Biomass is filled in the plasma reactor; the input power and the discharge frequency of an AC power source are adjusted, and CO2 gas is reduced; mixed gas obtained through the reaction is delivered through the H2O absorption cylinder, such that H2O is removed through absorption; the mixed gas is delivered through the organic gas absorption cylinder, such that organic gas is removed through absorption; CO gas obtained through the separation process by using the pressure swing adsorption apparatus is compressed by using a compressor, and is stored in the gas storage cylinder; CO2 gas obtained through separation is resolved by using a vacuum pump, and is delivered into a gas inlet of the plasma reactor for cyclicalreduction. With the method, the CO2 reduction efficiency is high, and the reduction cost is greatly reduced. CO2 is subject to cyclical reduction, such that the cyclical utilization of carbon resource is realized.

Description

technical field [0001] The invention relates to a dielectric barrier discharge plasma combined with biomass to reduce CO 2 The device and method belong to the technical field of environmental pollution control. Background technique [0002] The greenhouse effect and global warming have become one of the global environmental problems, how to effectively reduce CO emissions 2 It is one of the environmental issues that countries pay close attention to at present. CO 2 It is not only the main greenhouse gas, but also an important resource. At present, many research teams in developed countries are working on finding the CO 2 Economical route to transformation. [0003] Due to CO 2 The direct activation of CO2 requires a large amount of energy input. In recent years, research fields such as electrochemistry, photochemistry, and plasma chemistry have tried to use unconventional reaction technologies such as high-energy fields, photons, and high-energy electrons to convert CO2...
