Problems solved by technology
[0004] However, at present, the most common hydrogen separation membrane - palladium or palladium alloy membrane, its filtration performance will gradually decline above 400 degrees Celsius, which is not suitable for natural gas recombination that requires more than 700 degrees Celsius and is also the most important hydrogen production technology Therefore, it is difficult to combine hydrogen filtration membrane with natural gas reforming reaction

Provided is a diaphragm type hydrocarbon recombination hydrogen production device, comprising a first recombination section, a first hydrogen filtering film section, a second recombination section, a second hydrogen filtering film section, and a main heat exchanger. The first recombination section is used to recombine feed to form first recombination atmosphere. The first hydrogen filtering film section is connected with the first recombination section and is used to filter the first recombination atmosphere to form a first product and first residual gas. The second recombination section is connected with the first hydrogen filtering film section and is used to recombine the first residual gas to form second recombination atmosphere. The second hydrogen filtering film section is connected with the second recombination section, and is used to filter the second recombination atmosphere to form second product and second residual gas. The main heat exchanger is connected with the first recombination section and the first hydrogen filtering film section, and is connected with the second recombination section and the second hydrogen filtering film section. The main heat exchanger provides thermal fluid and cold fluid, wherein the cold fluid is used to cool the first recombination atmosphere and the second recombination atmosphere before the first recombination atmosphere and the second recombination atmosphere respectively enter the first hydrogen filtering film section and the second hydrogen filtering film section.
Description
technical field [0001] The invention relates to a hydrogen generator, and in particular to a thin-film hydrocarbon recombination hydrogen generator. Background technique [0002] Hydrogen energy is a type of energy that may be used by humans in the future, and its use is mainly combined with fuel cell power generation or direct combustion. Recombination of fossil raw materials is currently the main hydrogen production technology, but because the ideal of large-scale hydrogen production with renewable energy is difficult to achieve in the short term, recombination will still be the main hydrogen production technology in the next 20-30 years. [0003] Membrane separation and recombination is one of the most concerned hydrogen production technologies in recent years. It uses hydrogen separation membranes to remove hydrogen from the reaction process, destroying the chemical balance and improving the conversion rate of reactants. At the same time, high-purity hydrogen is obtained...
