Design of manufacturing process for production of high reactivity poly-isobutylene from isobutylene
Abstract: High reactivity Poly-isobutylene has wide use in many fields，such as lubricant and fuel additives，emulsive explosives ，surfactants，detergents and anti-rust agent etc .Jilin Petrochemical Branch Company in China National petroleum Corporation has Possessed their own Proprietary technology in Producing high reactivity Poly-isobutylene Products and has already set up two industrial Plants for Producing high reactivity Poly-isobutylene.The Production capacity of each Plant was up to 20000t/a，which shared 90% of the gross domestic market. The development and improvement for this technique Possessed great importance and Potential application Prospect.
In this paper. The continuous cationic Polymerization was perform over a boron tri-fluoride catalyst at low-temperature from the small scale, large scale to industrial scale. Polymer grade isobutylene was used as raw material in order to Produce high reactivity .under these reaction conditions ,the terminate olefin content of the obtained polyisobutene was 60%-85%, Thus greatly developed the utilization value of C4. the industrial apparatus employs the distinguished polymerization process, that is continuous twin autoclaves and external cycle operation .the process insures the reaction stability、easy controlling and good products quality.
Keywords: Boron tri-fluorid; poly-isobutylene (PIB); polymerization; isobutylene; double continuous polymerization reactor
