Abstract

The invention relates to the field of utilization and conversion of carbon dioxide, in particular to a preparation method of gathering and catalytic cyclic utilization of carbon dioxide. The method includes that carbon dioxide which is gathered from smoke and generated through pyrolysis is catalyzed by high-power plasma to generate carbon monoxide, and the carbon monoxide is gathered and recycled after being used for combustion or industrial application. The method had the advantages that through the synergistic effect of carbonic acid, catalysts, active agents, the gathering efficiency of the carbon dioxide is obviously promoted, the carbon dioxide is decomposed by solution rapidly to reduce decomposition cost, under the synergistic effect of the plasma, the catalysts and the active agents, the conversion temperature of the carbon dioxide is obviously reduced, the conversion ratio of the carbon dioxide is obviously promoted, the method is energy-saving and environment-friendly, saves fire coal by 10-85% and achieves near zero release of the carbon dioxide, the equipment investment is small, the carbon dioxide resource can be gathered, converted and recycled by a large amount, and the method is suitable for large-scale energy conservation and environmental protection in the major coal consumption industries.

Description

technical field [0001] The invention relates to the field of utilization and conversion of carbon dioxide, in particular to a preparation method for carbon dioxide capture and catalytic recycling. Background technique [0002] CO 2 As the main culprit of the atmospheric greenhouse effect and an important factor in global weather anomalies, reducing CO emissions 2 It is one of the important research topics nowadays. According to statistics, CO 2 The annual emissions are increasing year by year. By the end of 2006, the global CO 2 emissions have reached 6.2 billion metric tons, and the amount of CO in the atmosphere today 2 Levels are 27% higher than in the past 650,000 years, a very grim figure. in CO 2 Among the emission sources, coal-fired power stations account for the vast majority, followed by some industrial waste gas emissions and global vehicle exhaust emissions. In addition, there are some domestic exhaust gases. The emissions of these exhaust gases greatly...
