Description

Technical Field

[0001] This utility model relates to the field of plasma thermocatalysis technology, and in particular to a micro plasma thermocatalytic reaction device. Background Technology

[0002] Catalytic reactions are chemical reactions that occur under the action of a catalyst. The development of catalytic reaction technology has not only met the needs of daily life but has also greatly promoted the development of related fields. Currently, catalytic reaction technology is widely used in the chemical industry, petroleum processing industry, food industry, and other industrial sectors. Plasma catalysis involves using a plasma power source in conjunction with a reactor to activate raw material gases to form a plasma-ionized gas state. This plasma is composed of a large number of electrons, ions, neutral atoms, excited-state atoms, photons, and free radicals, exhibiting overall electrical neutrality while possessing extremely high molecular activation capabilities. For chemically reactive molecules that are difficult to activate using conventional methods, such as small molecules like CH4, CO2, N2, and H2O, as well as thermodynamically limited reactions, plasma activation offers significant advantages.

[0003] Furthermore, heating to create a high-temperature environment can increase the energy of matter and disrupt its original stable structure, thus making chemical reactions more intense. While some technologies place catalytic reactions under high-temperature and high-pressure environments, there is a lack of research on the correlation and synergistic effects between plasma external fields and catalytic reactions under high-temperature conditions. There is also a lack of dedicated reaction equipment. Therefore, it is necessary to provide a research device that can coordinate plasma catalysis and thermal catalysis environments for plasma catalysis research. This device would overcome the catalytic conditions that cannot be met by using plasma catalysis or thermal catalysis alone, or explore a milder reaction method to reduce the power of plasma catalysis or thermal catalysis, thus addressing the need for related scientific instruments in research.
