Introduction of HY molecular sieve

HY molecular sieve is a hydrogen molecular sieve with Y-type crystal structure, which is directly calcined by replacing NaY molecular sieve with ammonium.

Main routes:

Cyclohexane nitrosation reaction;

Synthesis of Acetylphenol;

Synthesis of isopropyl aniline;

FCC catalytic cracking;

Adsorption of organic gases;

Catalyst carrier

Synthesis of methanol and dimethyl ether;

Removal and adsorption of basic nitrogen compounds in oil;

Catalyzes the alkylation of thiophene sulfides in FCC gasoline;

Packing: non-dangerous goods, stored in a dry and airtight manner, no open storage.
