Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a methane catalyst furnace. Background Art

[0002] The krypton-xenon refining process involves the reaction of oxygen and methane using a palladium catalyst to produce carbon dioxide and water. These carbon dioxide and water are then removed using a molecular sieve. The remaining gas is fractionated through a distillation tower, utilizing the differences in boiling points between krypton (boiling point -152.30°C), xenon (boiling point: -107.1°C), and the main component, oxygen (boiling point -182.962°C). The remaining oxygen is released into the atmosphere. The raw material is liquid oxygen containing krypton and xenon, and the cooling source is liquid nitrogen.

[0003] When using existing methane reformers, high-temperature conversion easily leads to reformer burnout accidents, a short catalyst life, and if the raw materials do not fully contact the catalyst, a low conversion rate is likely to occur, leading to a waste of raw materials.
