Abstract
Abstract An improved process using a rare earth-containing catalyst is provided. The catalyst comprises a composite of matrix and rare earth or of zeolite, rare earth and matrix, usually alumina. The rare earth can be a single metal or a mixture of rare earth metals. The process involved is the conversion of alcohols or ethers to gasoline boiling range hydrocarbons.
