Abstract:
A process for hydrogenating long chain hydrocarbon waxes, which process comprisescontinuously feeding a long chain hydrocarbon wax feedstock into a slurry bed comprising a slurry of catalyst particles in a slurrying liquid, with the slurry bed being contained in a reaction zone and the feedstock entering the reaction zone at a low level;continuously feeding a hydrogenation component into the slurry bed, also at a low level;allowing the hydrogenation component to react with the feedstock, thereby to hydrogenate the feedstock, as the feedstock and hydrogenation component pass upwardly through the slurry bed;withdrawing hydrogenated waxes from the reaction zone at a high level, as a hydrogenated product, with the catalyst particles having an Overall Catalyst Performance Factor (`OCPF`) such that the Saybolt colour of the hydrogenated products is in excess of 15; andwithdrawing any excess hydrogenation component from the reaction zone at a high level.
