COMBINED METHOD OF SIMULTANEOUS PRODUCTION OF ALKYL-TERT-BUTYL ETHERS AND 1-BUTENE

摘要

FIELD: petrochemical processes. SUBSTANCE: method includes introducing stream of C-hydrocarbons into etherification unit, recycling residual stream into the same unit after possible separation of 1-bytene, transforming remaining butenes into isobutylene in isomerization section, and separating hydrocarbons in vapor phase with aid of molecular sieves. EFFECT: enhanced efficiency of process.
