TH127140B - The catalytic cracking process for the production of propylene - Google Patents

Abstract

The process opens up through the catalytic cracking process for the production of pyrpropylene, in which heavy feed and catalysts are introduced into the first set pipe; Cracking and catalytic heavy oil is introduced into a second set pipe that is welded in contact with the fluidized bed; Light hydrocarbons It is introduced into the pipeline set at the second major imports of heavy oil; Mixture of reaction from a set pipe The second is inserted into the fluidized bed; Mixture of reaction from the first upright pipe And fluidized bed It is separated in the product separation system to obtain cracked heavy oil, which can then be reused back to the second set pipe. The process is beneficial in the production of polypropylene, and would be a good replacement for heavy oils, the high yield of propylene and butylene, and a good alternative condition. For dry gas and coke
