Introduction

Richard D Doctor is an accomplished inventor based in Glen Ellyn, IL (US). He holds a total of 3 patents that showcase his expertise in the field of magnetic separation and petroleum processing. His innovative approaches have contributed significantly to advancements in these areas.

Latest Patents

One of his latest patents is titled "Process for magnetic beneficiating petroleum cracking catalyst." This process involves beneficiating a particulate zeolite petroleum cracking catalyst that contains metal values exceeding 1000 ppm nickel equivalents. The catalyst is subjected to a magnetic field ranging from about 2 Tesla to about 5 Tesla, generated by a superconducting quadrupole open-gradient magnetic system. This method effectively separates the catalyst into zones with varying nickel equivalent concentrations, allowing for efficient recycling and treatment of the materials.

Another notable patent is "Apparatus for magnetic separation of paramagnetic and diamagnetic." This invention focuses on segregating paramagnetic from diamagnetic particles in particulate material, particularly in coal. The apparatus consists of a vertical cylinder and a rotatable vertical screw, which facilitates the migration of denser paramagnetic particles to the outside while less dense diamagnetic particles move towards the center. The application of an open gradient magnetic field enhances the segregation process, leading to improved efficiency in coal processing.
