Abstract

The invention discloses a preparation method of a graphene-based carbon dioxide trapping agent. The graphene-based carbon dioxide scavenger has the following components and contents: SiC:20-23.5 wt%,CuO:0.1-0.3 wt%, cO2:20-30 wt%, Fe(OH)2: 20-34 wt%, Mn:1.03-0.14 wt%, Zn:0.03-0.04 wt%, Ag:0.003-0.004 wt%, Wu:100-150ppm, and the balance being excess NH3 and CO2 generated in the process. The deposition process of introduced carbon dioxide gas is controlled for 1-50 minutes; preferred 5-10 min, wherein the external temperature is kept at 10 to 100 DEG C; preferred 25 degrees. The beneficial effects of the preparation method are that: ammonia gas and carbon dioxide are utilized; the graphene powder capable of reacting is added and combined to prepare the fine degradation trapping agent, suchthat the capturing requirement on greenhouse gas can be well met, the multi-time use can be achieved, no by-product is generated, and the domestic and overseas market requirements can be well met.

Description

technical field [0001] The invention relates to a graphene-based carbon dioxide capture agent, in particular to a preparation method of the graphene-based carbon dioxide capture agent. Background technique [0002] With the continuous development of the industrialization process, the problem of global warming has been caused by the increase of the concentration of carbon dioxide in the atmosphere. The main reason for the increase of the concentration of carbon dioxide in the air is the burning of fossil fuels used in the energy industry, starting from the early industrialization in the 19th century So far, the concentration of greenhouse gases such as carbon dioxide and methionine in the air has been increasing, and its concentration has begun to increase significantly since the middle of the 20th century. As global warming continues to accelerate, the regulation of the emission and disposal of these greenhouse gases has also been strict. [0003] For my country, in order t...
