What are the raw materials and production processes used for isobutylene production, and what are the common equipment utilized?
This post was last edited by sdwfsgyykai on 2018-6-15 08:08. Dehydrogenation of isobutane to isobutylene is the most common method.
Dehydrogenation of isobutane to isobutylene: equipment includes reactors, heating furnaces, compressors, and mechanical pumps.
This raw material is usually MTBE, and in terms of purity, it is over 99.5%. The equipment is basically the same in the chemical industry: heat transfer oil furnaces, reactors, compressors, water wash towers, drying towers, light-end removal towers, and weight removal towers
Isobutylene is produced through the isomerization of butene, as well as via the dehydrogenation of butane. Additionally, isobutylene is present in the C4 components within catalytic cracking units. It can also be obtained by the cracking of tert-butanol or MTBE
Production of high-purity isobutylene via MTBE decomposition
Among these production processes, which one has the greater advantages? ?
The manufacturing process is still determined by the source and properties of the raw materials. Could you share the main sources of these raw materials?
The mixed C4 resulting from ethylene cracking, along with the raffinate oil obtained after butadiene extraction, contain approximately 45% isobutylene in these raw materials
