Embodiment

[0012] The methane-enriched gas plasma synthesis process of hydrogen in this embodiment comprises the following steps:

[0013] (1) The methane-rich gas with a methane content of 900%, or its mixture with water vapor and carbon dioxide, enters the heat exchanger at the lower part of the plasma reactor, and exchanges heat with the hydrogen-rich gas at 1300°C after reaction. Methane-enriched gas or mixed gas is heated to 300°C;

[0014] (2) The heated methane-enriched gas or mixed gas enters the heat exchanger in the wall of the plasma reactor to exchange heat with the wall of the plasma reactor. After the methane-enriched gas or mixed gas is reheated, the temperature rises to 1200 ℃;

[0015] (3) The reheated methane-enriched gas or mixed gas enters the plasma reactor, interacts with the plasma jet rich in active particles generated by the plasma generator at 2500°C in the reaction zone, and generates the following within 500ms under normal pressure Hydrogen-rich gas with hyd...

Abstract

Within the present invention discloses a methane-rich gas plasma synthesis process of hydrogen. According to the process, methane-rich gas is subjected to heat exchange with reaction high-temperature tail gas, and then is subjected to heat exchange with the wall of a plasma pyrolysis gasification reactor, and the obtained gas enters the plasma pyrolysis gasification reactor and acts with the plasma jet flow produced by a plasma generator to generate the gas adopting hydrogen gas as the main component. According to the present invention, the difficult problems that the traditional process requires the catalyst and the catalyst easily produces carbon precipitation, sulfur poisoning, halogen poisoning and arsenic poisoning are overcome, and the problems of the high energy consumption and the reactor wall protection during the plasma-to-hydrogen process are solved; and the process has characteristics of short process, simple operation, high thermal efficiency and low environmental pollution, and is suitable for the fuel gas chemical industry field and the plasma chemical industry field.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a hydrogen-enriched methane gas plasma synthesis process. Background technique [0002] Hydrogen has a very low density and can be used as a filling gas for airships. However, due to its flammability and low safety, airships are often filled with helium. Hydrogen is still primarily used as a reducing agent. The heat released by hydrogen combustion is large, and the product is non-polluting, so it is known as clean energy. Due to the difficulty in the source of hydrogen, it has not been used as the main fuel, but the scientific community has not given up on the exploration of hydrogen energy development. In the current hydrogen synthesis process method, the process is not easy to implement, the purity of the produced hydrogen product is low, the reaction residue cannot be recycled, the production process is complicated, the production efficiency is low a...
