Vehicle-mounted online reforming catalysis and hydrogen production device

Abstract

The invention discloses a vehicle-mounted online reforming catalysis and hydrogen production device which comprises a reaction cavity, a microwave power tube, a microwave plasma reaction tube, a catalyst and an ignition discharge device, wherein the microwave power tube is arranged in the reaction cavity, and microwave electric fields are formed in the reaction cavity; the microwave plasma reaction tube is arranged in the reaction cavity, and is hollow, a gas inlet end opening and a gas outlet end opening are formed in the microwave plasma reaction tube, and the gas inlet end opening and the gas outlet end opening get out to the outer part of the reaction cavity from the reaction cavity; the catalyst is arranged in the microwave plasma reaction tube, and comprises a plurality of spherical catalyst particles which are connected together through metal wires in a penetrating mode; and the ignition discharge device is inserted into the microwave plasma reaction tube, and can discharge under action of the microwave electric fields, so that mixed combustible gas in the microwave plasma reaction tube is broken down. According to the vehicle-mounted online reforming catalysis and hydrogen production device disclosed by the invention, the yield of hydrogen-rich gas is increased, and economical efficiency of the whole device further can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted on-line hydrogen production, in particular to an improved vehicle-mounted on-line microwave plasma hydrogen production device arranged with catalysts. Background technique [0002] At present, the vehicle-mounted online hydrogen production technology has become the key direction of the development of new automotive internal combustion engines. Using the vehicle-mounted online hydrogen production technology can improve the fuel, which can not only improve the operating economy of the engine, but also reduce the harmful gas of vehicle exhaust to the greatest extent. emission. Among them, using microwave plasma reformer to generate reforming reaction is an important method to produce hydrogen on-line. [0003] The microwave plasma reformer uses the microwave emitted by the microwave power tube in the reformer to excite the combustible mixed gas to generate plasma, and the plasma promotes the...
