Product Details
1, technical characteristics
C (U) supporting protective agent is a kind of new packing plant in recent yearsimproved. The main is to improve the material quality, metal oxide to increase the amount of products, increase the surface area, improve the gas flow, heat transfer performance is greatly increased, to better protect the catalyst, improve its service life. With the development of C (U) supporting protective agent performance is greatly improved, now has become an increasingly widespread use.
2, main application range
Major in chemical equipment of isomerization, aromatization unit, ethylbenzene unit,four carbon alkene saturation device regeneration system and no supporting fixedbed catalytic reactor support.
