Product Applications

It is mainly used to produce isopropyl alcohol, acetone, synthetic glycerol, synthetic resin, synthetic rubber, plastic and synthetic fiber, etc. It is used as the raw material of polypropylene; Propylene is an important chemical raw material. Acrolein obtained by gas phase oxidation of propylene is used to produce acrylic acid, allyl alcohol, glyceraldehyde, hydroxyacetaldehyde and..

Production method

1. Catalytic cracking gas in refinery removes C2 and C4 fractions by distillation to obtain propylene and propane fractions, and then rectifies to produce propylene. 2. The product of high temperature cracking of petroleum hydrocarbons is a joint product of ethylene production. 3. Propane dehydrogenase. The catalyst is chromium oxide-alumina, the reaction temperature is ℃, the propane conversion rate is 54%, The propylene selectivity is 76%, and the recovery rate is 93% (molecular ratio).
