Abstract
A catalyst for production of alkyl tert alkyl ether from sulfur contaminated feedstock includes an ion exchange resin; a palladium first metal phase supported on the resin; and a sulfur inhibiting second metal phase supported on the resin for inhibiting sulfur deactivation of the first metal phase, wherein the first metal phase is present at an atomic ratio to the second metal phase of between about 1:20 to about 1:0.1. A process for producing alkyl tert alkyl ethers includes the steps of providing a liquid olefinic hydrocarbon feedstock containing sulfur and having a total sulfur content of up to about 300 ppm; providing a catalyst as described above; mixing the feedstock with alcohol and hydrogen to obtain a reaction feedstock; and contacting the reaction feedstock with the catalyst under etherification conditions so as to produce alkyl tert alkyl ether.
