Description

technical field [0001] The invention relates to the technical field of hydrogen production auxiliary devices, in particular to a natural gas carbon-free hydrogen production device. Background technique [0002] With the increasing environmental problems caused by the burning of fossil energy, the transition from traditional fossil energy to clean and renewable energy is imminent. Hydrogen energy is a clean and renewable energy with the advantages of high combustion calorific value, good safety, and multiple source paths, and is considered to be an ideal clean fuel. However, under the current technology, the widespread use of hydrogen energy is greatly restricted by its production costs and storage and transportation costs. Therefore, the development of advanced hydrogen production technologies with low carbon emissions, low energy consumption and low cost is an important guarantee for obtaining cheap hydrogen sources. The key to promoting the smooth transition of the energy...

Problems solved by technology

This will not only reduce production efficiency due to shutdown, but also increase additional labor costs; secondly, the structure of carbon products is closely related to its growth time. In order to obtain high-value carbon products, it is necessary to control the growth time of carbon on the surface of molten metal; Including molten metal will produce metal vapor at high temperature, metal vapor will be discharged out of the reactor with gas and carbon products

Due to the different vapor pressures of different molten metals, the amount of metal lost after running for the same time is also different, which will lead to changes in the composition of the molten alloy and a decrease in catalytic efficiency

If the reactor is stopped for sampling analysis and adding metals, there is a problem of difficult sampling after condensation, and the shutdown will lead to a decrease in production efficiency and an increase in cost
