Abstract
Low concentrations of methanol and dimethyl ether in distillation column C.sub.4 -C.sub.5 raffinate produced in the formation of methyl tert.-alkyl ethers by the reaction of methanol with isoalkylenes are effectively removed from the residual C.sub.4 -C.sub.5 hydrocarbons by adsorption on a dual or compound adsorption bed containing silica gel as the methanol adsorbent and zeolite 13X as the dimethyl ether adsorbent.
