Abstract

The invention discloses a device and a method for producing hydrogen by catalytic cracking of natural gas or coalbed methane, and belongs to the technical field of hydrogen preparation. The natural gas or coalbed methane catalytic cracking hydrogen production device comprises a main reaction device, a gas-solid separation device, a catalyst recovery device, a nano carbon storage tank, a gas purification device and a high-purity hydrogen storage tank. The invention also discloses the method for producing hydrogen by catalytic cracking of natural gas or coalbed methane by using the device for producing hydrogen by catalytic cracking of natural gas or coalbed methane. The natural gas or coalbed methane catalytic cracking hydrogen production device can realize online real-time separation of gas-solid and gas-gas, is suitable for a continuous hydrogen production process, and has a carbon sequestration effect on raw material gas (alkane gas such as natural gas and coalbed methane), i.e., a process product is solid nanocarbon without carbon dioxide emission. In addition, closed circulation is formed after tail gas purification, comprehensive utilization of waste heat is improved after heat exchange, and overall comprehensive energy consumption is reduced.

Description

Technical field [0001] The invention relates to a device and a method for producing hydrogen by catalytic cracking of natural gas or coalbed methane, and belongs to the technical field of hydrogen preparation. Background technique [0002] In 2015, the world reached the "Paris Agreement" to address climate change. The situation of tackling climate change is becoming more and more urgent, and most countries are actively developing low-carbon new energy sources to fulfill their commitment to tackling climate change. In addition to the mainstream of renewable energies such as wind power and solar energy, the development of hydrogen energy has gradually attracted attention due to its high efficiency, cleanliness and ease of large-scale storage. Some countries and regions such as the United States, the European Union, Japan, and South Korea have made large-scale investments in hydrogen energy basic research and applied research. [0003] Hydrogen energy is a highly efficient energy so...
