ABSTRACT "Process for the Manufacture of Methyl t-Butyl Ether" A process is provided 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 the 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. The process results in an integrated, economic means for the production of methyl t-butyl ether.
