High purity isobutylene can be produced by TBA dehydration catalyzed by resin catalyst, it can be used to produce chemical products such as MMA, OTC, butyl rubber, polyisobutylene and so on. 

Technical features:

1. Simple process, only a catalytic distillation column and a fractionation column are required.

2. Low temperature, low energy consumption and low investment, 60% lower in budget than the traditional process using inorganic catalytic.

3. The purity of isobutylene is more than 99.8wt%.

4. The catalyst have a service life of more than 3 years.
