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.

Process for manufacturing methyl tertiary-butyl ether (MTBE) and other hydrocarbons

A propylene production process is disclosed. The process comprises (a) reacting a feed stream comprising isobutene in the presence of a skeletal isomerization catalyst to obtain an isomerized stream comprising Colefins; and (b) reacting the isomerized stream with ethylene in the presence of a metathesis catalyst to form a metathesis product stream comprising propylene, Colefins, and C+ olefins. The metathesis reaction pressure is equal to or lower than that of the skeletal isomerization.
