Title: Inventor Marvin I Greene: Pioneering Carbonaceous Material Technologies
Introduction
Marvin I Greene, an innovative inventor based in Oradell, NJ, has made significant contributions to the field of carbonaceous material technologies. With a total of five patents to his name, Greene has been a key figure in advancing methods for liquefying solid carbon materials.
Latest Patents
Greene's latest inventions include two notable patents that focus on the liquefaction of solid carbonaceous materials. The first patent addresses the "Liquefaction of solid carbonaceous material with catalyst recycle." In this two-stage liquefaction process, coal is liquefied in the presence of a liquefaction solvent during the first stage, followed by hydrogenation of the first stage effluent in the second stage. The process incorporates a catalyst, previously used in the second stage and reduced to a particle size distribution that passes through U.S. 100 Mesh, to enhance overall operation efficiency.
The second patent, titled "Co-processing of carbonaceous solids and petroleum oil," details a method for producing distillates from coal by employing a first stage of thermal liquefaction, succeeded by catalytic hydrogenation. This innovative approach allows for the addition of liquefaction solvent at various points along the thermal liquefaction heater, enabling the co-processing of coal with petroleum oil, either by introducing pre-hydrogenated oil in the first stage or unhydrogenated oil in the second stage.
