Abstract
A process for preparing alkyl tert alkyl ethers includes the steps of providing a liquid olefinic hydrocarbon feedstock having a sulfur content, providing an ion exchange resin containing an amount of palladium selected based upon the sulfur content of the liquid olefinic hydrocarbon feedstock, mixing the liquid olefinic hydrocarbon feedstock with alcohol and hydrogen so as to obtain a reaction feedstock and treating the reaction feedstock with the ion exchange resin under etherification conditions so as to obtain an alkyl tert alkyl ether.
