Abstract: The present invention describes a process for the production of base oils having a viscosity of greater than 4 centistokes from waste oils originating from industrial use or engine use, said process using a novel configuration for efficient and effective processing.

Abstract: A radial flow distribution system, a radial flow reactor, and components thereof, including one or more of a scallop, center pipe, and/or outer basket. Each of the scallop, the center pipe, and the outer basket has openings formed therein. wherein the sizes or the shapes of the openings vary along the length or the width of the reactor components such that the openings define a pattern in configured to manipulate and optimize the distribution of flow of feedstock out of the components and through the reactor to maximize the efficiency of the catalyst reaction thereof.

Abstract: A scallop, center pipe, and outer basket for use in a radial flow reactor are provided. Each of the scallop, the center pipe, and the outer basket is formed of an elongated conduit having a top end and an opposing bottom end, and a plurality of openings formed in the elongated conduit through a thickness thereof. A diameter of the plurality of openings progressively increases or decreases from the top end to the opposing bottom end of the elongated conduit so as to allow a feedstock to flow radially out through the plurality of openings on the scallop or outer basket, or to allow a feedstock to flow uniformly into the center pipe through the plurality of openings. A system utilizing the center pipe together with either the scallop or the outer basket is also provided.
