Reforming hydrogen production device and hydrogen production method using the same

Abstract

The invention discloses a method of reforming diesel oil with non-thermal arc plasmas to produce hydrogen. A plasma reactor mainly comprises an air-assisted atomizing nozzle, electrodes, insulating ceramics, a gas distribution component and a post-treatment section of plasma reaction. Diesel oil can be atomized by the nozzle at the upper end of the reactor and then enters an area where plasmas arelocated, undergoes evaporation and then reacts. Also the diesel oil can be gasified together with water by an evaporation chamber and is then mixed with air, the mixed gas enters the gas distributioncomponent from the middle part of the reactor, the gas passing through the gas distribution component has tangential and radial velocities, and under the action of a high voltage electric field, stable plasmas can be produced between the electrodes. The reacted gas can be further subjected to a section of catalytic reaction so as to further increase the hydrogen content. The invention has the advantages that: the reactor has compact structure and low power consumption, can adopts gas phase or liquid phase feeding, and can reform diesel oil and other macromolecular fuels into mixed gas containing hydrogen for use by fuel cells.

Description

technical field [0001] The invention relates to hydrogen production technology, in particular to a reforming hydrogen production device, and also relates to a non-thermal arc plasma hydrogen production method using the device. Background technique [0002] As a chemical energy technology that converts chemical energy in fuel directly into electrical energy through electrochemical reactions, fuel cells have the advantages of high efficiency, cleanliness and safety, and are considered to be one of the most promising alternative energy technologies. The best fuel for fuel cells is hydrogen. Since the birth of fuel cells, hydrogen sources, like fuel cells themselves, have been important core technologies. At present, the hydrogen sources of fuel cells mainly include high-pressure hydrogen storage and fuel reforming hydrogen production. High-pressure hydrogen storage has limited its application in fuel cells due to its low volumetric energy density, high cost, and lack of hydrog...

Problems solved by technology

Due to the use of rare metals in catalytic reforming, the investment cost is high, and the catalyst is prone to poisoning and carbon deposition, so it needs to be replaced regularly

In addition, the catalytic reaction needs to be at a higher temperature, and it takes more time to preheat the catalyst, and the start-up time is long
