Problems solved by technology

CO 2 The gas is stored underground and does not store CO 2 Consume or convert away, and sequester CO 2 It has high requirements on geological conditions, and the storage process needs to consume a lot of energy, so it is not a better way to deal with the final products of petrochemical fuels
[0007] In recent years, countries have gradually adopted other forms of natural resources such as sunlight to reduce CO 2 It is an ideal method to capture and effectively reduce it into usable hydrocarbon fuels, but the main difficulty of this type of method is (1) CO 2 Stable and difficult to capture; (2) CO 2 Important photocatalytic active substance CO 2 - reduction potential CO 2 / CO 2 - Up to -1.9V (PH=7) is not easy to carry out; (3) the existing relatively mature photocatalyst TiO 2 (Band gap 3.2eV) is that the utilization rate of sunlight by ultraviolet photocatalyst is too low (ultraviolet light accounts for less than 4% of sunlight), and the catalytic effect is not good

Abstract

The invention belongs to the field of environmental engineering and specifically relates to a method for reducing haze and generating hydrocarbon fuel methanol for treating petrochemical burning emission. The method comprises the following steps: (1) preprocessing; (2) feeding the CO2 gas acquired in the step (1) into a photo-catalytic reactor filled with saturated NaOH aqueous solution containing SrTi1-xFexO3-delta (x is more than or equal to 0 but less than or equal to 1 and delta is more than or equal to 0 but less than or equal to 1) through a pipeline, controlling the pressure in the photo-catalytic reactor and stopping conveying CO2 gas when the pH value of the solution in the photo-catalytic reactor is 8.3-8.4; (3) performing photo-catalytic reaction and ending the reaction when the pH value of the solution in the photo-catalytic reactor is 11-14; (4) performing distillation condensation collecting reaction on the hydrocarbon fuel generated in the photo-catalytic reactor in a water circulation constant temperature bath.

Background technique [0002] Energy, environment, and climate are the three major issues facing mankind. More than 90% of the energy currently used comes from petrochemicals. The final products of petrochemical energy are mainly CO 2 Mainly, in addition, it also contains a small amount of nitrogen oxides and sulfur oxides. A lot of CO 2 The emission of carbon dioxide causes environmental pollution, high carbon emissions, and climate warming; nitrogen oxides, sulfur oxides, and dust are the main sources of smog.
