Abstract
An internal combustion engine fuel is produced from a mixture of hydrocarbons comprising olefinic hydrocarbons containing 5 to 8 carbon atoms characterized in that it is produced by a process comprising a) a catalytic etherification step for at least a portion of the etherifiable olefins contained in said hydrocarbon mixture, using at least one alcohol containing 1 to 4 carbon atoms, the quantity of alcohol employed being such that the alcohol:etherifiable olefin molar ratio is at least 1:1, and b) a water washing step for the ether-containing product before recovery as a fuel.
