Description
Technical Field
The invention relates to the technical field of carbon dioxide-methane reforming, in particular to a carbon dioxide-methane plasma high-temperature reforming device and a high-temperature reforming method.
Background
Carbon dioxide, the most abundant carbon source, is widely distributed in the earth's atmosphere, the crust. As an end product of the combustion of carbonaceous material, it is also a fairly stable resource of C1, with an average CO ═ O bond energy of about 5.5eV, i.e. 532 kJ/mol. The main component of natural gas is methane. Chemical utilization of natural gas can be roughly divided into two approaches: the first is a direct conversion method, which is to convert natural gas directly into a certain chemical product. The other is indirect conversion method, which is mainly to convert the synthesis gas into other chemical products. Therefore, from the viewpoint of resource utilization and environmental protection, research on the conversion of two stable C1 compounds, namely carbon dioxide and methane, is of great significance, and the comprehensive utilization of the compound can not only reduce the emission of carbon dioxide, but also alleviate the problem of increasingly scarce fossil resources.
The essence of the chemical reaction is the recombination of atoms or groups of atoms, and molecular activation requires energy. Whereas methane carbon dioxide reforming requires a large activation energy. In recent years, on the one hand, a large number of works have been carried out with great success in terms of catalyst selection, catalyst and carbon deposition behavior, catalytic reaction mechanism, and the like, but there are disadvantages in that catalytic activity is high, and for example, a carrier or a metal is sintered or undergoes a solid phase reaction under high temperature reaction conditions, and the catalyst is deactivated, resulting in a shortened service life. Therefore, the application of various unconventional methods is also widely discussed, wherein the application research of the plasma technology in the aspect of preparing the synthesis gas by reforming methane and carbon dioxide is more active, the reaction condition of the plasma technology is more excellent, the disadvantages of high stability and thermodynamics of methane molecules and carbon dioxide molecules can be overcome, and the effect of a catalyst can be replaced, namely the effect of CO2-CH4The conversion into chemical raw materials with high added value provides a brand-new activation means and a new way for reforming.
