    Abstract: A process for the production of tertiary alkyl ethers from a feed containing tertiary alkenes and diolefins comprises the following steps:
    (a) subjecting the feed to a hydrogenation step to selectively hydrogenate the diolefins employing, as catalyst, sulphided nickel on a support, the catalyst containing at least 40% by weight of nickel based on the total weight of nickel and support, (b) subjecting the hydrogenated feed to an etherification step which comprises reacting the tertiary alkenes with an alcohol in the presence of an etherification catalyst to form tertiary alkyl ethers. The feed containing tertiary alkenes can be a light catalytically cracked spirit obtained from the catalytic cracking of mineral oils and the alcohol can be methanol and the product from the etherification step contain one or more of tertiary butyl methyl ether, tertiary amyl methyl ether, tertiary hexyl methyl ether and tertiary heptyl methyl ether.
