Method and device for producing hydrogen by microwave

Abstract

The method comprises the following steps (a) to (b): in step (a), the raw material and the catalyst are uniformly dispersed to prevent the sedimentation from occurring; in the step (b), The raw materials and the catalyst are fed into a microwave resonance reaction unit in a micro-droplet state through an atomization device. The raw materials can continue to undergo microwave action and further disintegrate into smaller-scale clusters to cause hydrogen production by pyrolysis. In the process of droplet disintegration, the raw material receives stimulated emission electrons generated by the microwave antenna in the reaction unit to enhance the reaction rate. The above-mentioned reaction process achieves better pyrolysis efficiency with the help of the catalyst, and finally produces hydrogenand outputs for utilization. The device comprises a microwave resonance reaction unit, a DC power supply, a material storage device, an atomization device, a microwave generator and a gas storage device, so as to greatly improve the catalytic efficiency and cause hydrogen cracking The reaction has low energy consumption and high efficiency.

Description

technical field [0001] The invention relates to the technical field of a hydrogen production method and a device thereof, in particular to a microwave hydrogen production method and a device thereof. Background technique [0002] Due to the high combustion calorific value of hydrogen, and the product of combustion is water, it is very likely to become an important secondary energy source on the world energy stage. Various countries have also invested in the research of hydrogen energy production. Taking the United States as an example, the United States produces about 9 million tons of hydrogen (molecules) every year, 95% of which are obtained by the reaction of water vapor and hydrocarbons. The general method is to pass water vapor through a carbon-containing compound with a nickel-based catalyst at high temperature, and then pressurize and adsorb to separate hydrogen. Commonly used carbon-containing compounds are coal and natural gas, and the products that react with wate...

[0007] However, although the above-mentioned No. M394324 new patent case uses an ultrasonic oscillator to produce water atomization effect, the excitation source of the reaction is a very energy-consuming plasma system, and it also lacks the catalytic reaction of the catalyst. Therefore, the catalytic efficiency is not ideal.
