Description

Technical Field

[0001] This invention belongs to the technical field of high-temperature and high-pressure catalytic reaction equipment, and particularly relates to a high-temperature and high-pressure carbon fixation catalytic reaction system. Background Technology

[0002] High C / H ratio methane reforming and dry natural gas reforming are two commonly used experimental hydrogen production methods in existing technologies. However, to achieve rapid reaction, a high-temperature and high-pressure environment is required. Traditional furnace structures used in these reactions are often made of a single material, and the single-material furnace tubes cannot simultaneously meet the requirements of corrosion resistance and mechanical strength under high temperature (1200℃) and high pressure (2.5MPa) conditions, potentially leading to reaction safety hazards and a shorter equipment lifespan. Furthermore, traditional reaction equipment lacks sufficient safety redundancy in its pressure relief system under extreme conditions. For example, it may fail to automatically vent when the pressure limit is reached, resulting in inadequate overall safety protection. Additionally, it cannot capture harmful gas molecules during the reaction, failing to provide reaction protection and potentially leading to experimental failure.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Summary of the Invention
