Application of Novel Ionic Liquids in Alkylation Technology

The alkylation technology using the composite ionic liquids(ILs)jointly developed by the China Huanqiu Northeast Engineering Company and the China University of Petroleum has been successfully applied in the 150 kt/a alkylation unit of PetroChina’s Harbin Petrochemical Company.Currently this unit runs stably,while cranking out the alkylate having an octane rating of 96 units with all quality indicators complying with the design targets.It is learned that this alkylation technology has reaped the second harvest to make a breakthrough in alkylation of C4 hydrocarbons。
