A method for plasma hydrogen production

Abstract

The invention discloses a method for plasma hydrogen production. The method specifically comprises the following steps: by taking water as a medium, performing laser induced water breakdown to generate plasma to provide seed electrons to contact glow discharge; providing seed electrons to laser induced water breakdown from the plasma generated from contact glow discharge simultaneously, establishing avalanche breakdown water to generate plasma, maintaining density of electrons of a laser ionization channel, and continuously generating water contact glow discharge plasma; producing hydrogen by using the plasma generated from water contact glow discharge. By adopting the method, contact low-temperature plasma can be generated with relatively low optical energy and electric energy, the difficulty in generating plasma from water contact glow discharge is solved, and thus low-temperature plasma hydrogen production by using water as a raw material is achieved.

Description

technical field The invention relates to the technical field of hydrogen production, in particular to a method for plasma hydrogen production. Background technique Hydrogen energy is an ideal green energy. Many countries have raised the development and utilization of hydrogen energy to the height of the national energy development strategy, and invested huge manpower and material resources to develop and utilize it. The conversion efficiency of hydrogen is high and the emission pollution is much smaller than that of internal combustion engines. The use of hydrogen energy can effectively reduce the emission of pollutants from automobiles and other equipment. It is one of the effective ways to solve the environmental problems of large and medium-sized cities like Beijing. In recent years, with the increasingly serious urban environmental pollution, more stringent restrictions on vehicle emissions have been put forward. Many researchers and automobile companies have invested a ...

Problems solved by technology

In recent years, with the increasingly serious urban environmental pollution, more stringent restrictions on vehicle emissions have been put forward. Many researchers and automobile companies have invested a lot of money in the research of fuel cells and hydrogen internal combustion engines. With the main technology of fuel cells The relative lag of its hydrogen production and supply technology has become a bottleneck factor restricting the commercialization of fuel cells and electric vehicles. Therefore, it is urgent to develop convenient, fast and diversified small and medium-sized hydrogen production technologies

However, the main raw materials for hydrogen production in the prior art are gasoline, diesel, natural gas, methanol, ethanol and other hydrogen-containing minerals or bio-oils. In current hydrogen production, 50% of the output comes from natural gas water vapor with methane as the main component. Hydrogen production by catalytic reforming, a large-scale production process

Obviously, the use of the above fuels to produce hydrogen does not solve the energy problem
