and the industry should accelerate its development pace

high-purity methane is a high-purity methane gas obtained through purification and fine processing. its purity generally reaches 99.995% (4n5) level and above. it can be used in the preparation of mixed gases, catalyst evaluation, carburization and carbides of metals and alloys. generation, microbial culture, refrigerants and chemical raw materials, etc. generally speaking, because high-purity methane is more expensive and low-purity pure methane can meet demand, high-purity…
