Abstract
A desulfurizing and dewaxing process which can be performed in a single reaction vessel is disclosed. The desired lowering of oil partial pressure for dewaxing zone is accomplished by adding diluent gas to the HDS-zone effluent, thus obviating the need for other means to maintain differing oil partial pressures between serial catalyst zones.
