F-3637 PROCESS FOR CONTINUOUS DEWAXING OF HYDROCARBON OILS A process for the shape-selective catalytic hydrodewaxing of a hydrocarbon oil, which comprises introducing the hydrocarbon oil, shape-selective dewaxing catalyst and hydrogen at an upper portion of a moving bed reactor, removing dewaxed hydrocarbon oil, partially spent catalyst, and unconsumed hydrogen at a lower portion of the moving bed reactor, separating the dewaxed hydrocarbon oil and the unconsumed hydrogen, reactivating the partially spent catalyst and returning the reactivated catalyst to an upper portion of the moving bed reactor at a rate such that the temperature within the reactor remains substantially constant. |
