PROCESS FOR MANUFACTURING METHYL TERTIARY-BUTYL ETHER (MTBE) AND HYDROCARBONS

摘要

(EN)A process for manufacturing methyl t-butyl ether (MTBE) including (A) an optional first step including cracking raw material made from or containing ethane and/or propane, to form ethylene and recovering the residual uncracked raw material, (B) a second step including dimerizing ethylene to form n-butylene, (C) a third step including isomerizing the n-butylene to form isobutylene, (D) an optional fourth step including oxidizing methane to form methanol, (E) a fifth step including etherifying the isobutylene with methanol to form methyl t-butyl ether, and (F) a sixth step including collecting the methyl t-butyl ether is provided. The process can also be used to prepare gasoline alkylate, a higher molecular weight ethylene oligomer, a higher-molecular-weight-ethylene-oligomer- based methyl ether, an isomerized higher molecular weight ethylene oligomer, or an isomerized-higher-molecular-weight-ethylene- oligomer-based methyl ether.
