PROCESS FOR THE JOINT PRODUCTION OF ETHERS AND HYDROCARBONS WITH A HIGH OCTANE NUMBER

摘要

A process is described for the joint production of ethers and hydrocarbons with a high octane number starting from C4 hydrocarbon cuts containing isobutene, by oligomerization with acid catalysts, in the presence of primary alcohols selected from methanol or ethanol in such a quantity as to have a molar ratio primary alcohols/isobutene in the feeding of between 0.2 and 0.7, preferably operating at a reaction temperature of between 30 and 100.degree.C and at feeding space velocities of less than 20 h-1.
