Isobutene is a kind of important basic organic chemical industry raw material.It is widely used in butyl rubber, polyisobutene, methyl-prop
The production fields such as e pioic acid methyl ester, tert-butylamine, methacrylonitrile.The production method of current high-purity isobutene mainly has methyl- tert fourth
Base ether (MTBE) cracking process and the tert-butyl alcohol (TBA) evaporation.The shortcomings that MTBE cracking process is that side reaction is more, to be gathered
Level isobutene product is closed, it is necessary to substantial amounts of separation equipment, flow complexity, investment and high energy consumption.The shortcomings that TBA evaporations is anti-
The ion-exchange resin catalyst heat endurance used in answering is insufficient, at relatively high temperatures intensity decreases, the catalyst after fragmentation
Cause reactor pressure decrease to become big, reduce the conversion ratio and yield of isobutene.
CN101260016A describes a kind of refining plant and process that high-purity isobutene is made by MTBE cracking,
For the method using MTBE cracking gases as raw material, six towers that light and de- weight is taken off using absorption, methanol dehydration and refined, isobutene are continuous
The separation of rectification process flow obtains isobutene product.
CN102020526B and CN102690159A describes a kind of method that isobutene is prepared using the tert-butyl alcohol, should
Fixed bed reactors and rectifying column are formed a system by method, are back to instead from rectifying column side take-off tertiary butanol and water mixture
Answer device, top gaseous phase extraction isobutene product.Existing diisobutylene knockout tower is complicated, it is impossible to isolates high-purity isobutyl
Alkene.
