Abstract

The invention discloses a novel microwave low-temperature plasma reformer system, and in particular relates to a vehicle-mounted microwave low-temperature plasma reformer system for online hydrogen production. The system is used for preparing a hydrogen rich gas by converting gasoline, diesel oil, alcohol, water and mixture thereof. According to the technical scheme, the system comprises two resonant cavities, namely a cylindrical resonant cavity and a rectangular resonant cavity. A new method of multi-port input in the tangential direction is designed, and plasma is stably generated through vortex airflow in the cavity of a reformer. According to two sets of gas output ports, namely a main gas output port and a sub gas output port, the power density in the cavity can be kept in a relatively low level. According to two rectangular cavity structures, a boron silicate glass tube is used in one design, so that the risk of polluting the microwave resonant cavity by chemical substances is reduced; and the partial resonant cavity is used as a chemical reactor in the other design, so that the designed structure is simple. An automatic starting technology for igniting the microwave low-temperature plasma when the microwave plasma is initially excited is also designed.

Description

technical field [0001] The invention relates to the microwave plasma on-line conversion hydrogen production technology of fuel and the control field of a vehicle-mounted low-temperature plasma converter, in particular to a hydrogen converter of a microwave plasma reaction chamber and a vehicle-mounted control system thereof. Background technique [0002] Hydrogen or hydrogen-rich gas is an excellent additive that can significantly improve the combustion characteristics of engine hydrocarbon fuels. Localized hydrogen enrichment technology applied to spark ignition and compression ignition engines can significantly reduce fuel consumption and polluting gas emissions. For vehicle applications, on-board generation of hydrogen or hydrogen-rich gases using hydrocarbon fuels such as gasoline, diesel, ethanol, etc. is a key technology. [0003] The technologies for reforming hydrocarbon fuel molecules into hydrogen or hydrogen-rich gas mainly include pyrolysis and electrolysis. In...
