Description

technical field

[0001] The invention relates to a method for preparing butene and butadiene, in particular to a method for preparing butene and butadiene by catalytic dehydrogenation of butane. Background technique

[0002] Butene is the basic raw material of petrochemical industry, second only to ethylene and propylene in petrochemical olefin raw materials, and is an important monomer of synthetic rubber and polymer materials. Generally speaking, butene mainly has several isomers, such as n-butene (1-butene), isobutene, cis-dibutene and trans-dibutene. N-butene is mainly used in the manufacture of methyl ethyl ketone, sec-butanol, butylene oxide and butene polymers and copolymers. Isobutylene is mainly used in the manufacture of butyl rubber, polyisobutylene rubber and various plastics. Generally speaking, 1-butene and 2-butene do not need to be separated, and can be chemically processed together to produce many important basic organic chemical products, such as hydration...
