Isobutane dehydrogenation technology refers to the catalytic dehydrogenation of isobutane to isobutene. Isobutene is an important chemical raw material, which can be used to produce MTBE, or with alkylation to produce isooctane, butadiene rubber, polyisobutene, methacrylic acid, isopentenol and other chemical products. It is considered as the most important raw basic chemical material in addition to ethylene and propylene.
In recent years, with the significant improvement of refinery production capacity and ethylene cracking capacity, there comes a large number of by-products of C4. Using isobutane as raw material to dehydrogenate isobutene can not only make better use of C4 resources, but also get products with higher additional value, which gives great contribution to society.
