The invention concerns a process for the manufacture of methyl t-butyl ether in which: a hydrocarbon feedstock is cracked to give an ethylene-rich stream; an isobutane-rich stream is separated from C4-hydrocarbon stream; the ethylene-rich stream and the isobutane-rich stream are contacted over a transhydrogenation catalyst to give a mixture comprising ethane and isobutene; the isobutene is reacted with methanol to give methyl t-butyl ether; and the residual C4-hydrocarbon stream is recycled either to the C4-hydrocarbon stream or to the cracker and the ethane is recycled to the cracker. It has been found that combining and interconnecting a hydrocarbon cracker, a transhydrogenation reactor and an etherification reactor results in an integrated, economic process for the production of methyl t-butyl ether. |
