Technical Field
The invention belongs to the technical field of hydrogen energy, and particularly relates to an anhydrous hydrogen production process which can convert hydrogen-containing raw materials (alcohol, alkane and the like) into hydrogen-rich gas under the condition that water is not supplied from the outside.
Background
The rapid development of social economy and the continuous improvement of the living standard of people not only increase the energy demand, but also put higher requirements on the sustainable development of the existing energy system, and the increasing exhaustion of fossil energy forces researchers to search environment-friendly renewable clean energy sources capable of replacing the fossil energy, which has practical significance on the energy and environmental protection strategy of China.
Hydrogen energy is a clean, renewable, secondary energy source, plays an important role in traditional chemical synthesis, and has been widely focused on energy utilization platforms with the development of fuel cell technology. The hydrogen has wide sources and various preparation methods, and can be prepared by various methods such as reforming or partial oxidation of alcohol ethers (methanol, ethanol, dimethyl ether and the like) and hydrocarbons (diesel oil, gasoline, natural gas and the like), ammonia decomposition, metal or metal hydride hydrolysis, water electrolysis, water photolysis, biological hydrogen production and the like. Among them, reforming of alcohols and hydrocarbons is still the main method for producing hydrogen.
In chemical production, a method of producing hydrogen by steam reforming is generally adopted, and the reaction process is shown in the following equation.
Fuel (C)nHmOp) + steam (H)2O)
→ small molecule carbon-containing compounds (CO, CO)2，CH4Etc. + -. 3H2ΔH＞0
However, because of limited raw material reserves in the hydrogen production by coal and petroleum reforming, the hydrogen production efficiency is low and certain pollution is caused to the environment, and particularly, the steam reforming technology is a process with high water consumption and high energy consumption similar to other coal chemical industry and petrochemical industry technologies.
Therefore, how to improve the reaction process in the reaction equation to achieve the aim of consuming less water or even not consuming water greatly expands the application field of the hydrogen production process. The traditional solution is to develop a catalyst with good carbon deposition resistance, and simultaneously, the catalyst has good oxygen storage and release performance, so that the steam reforming hydrogen production reaction can be realized under the condition of stoichiometric ratio, and the water consumption of the process is greatly saved.
