Title: Innovations of John W Taunton
Introduction
John W Taunton is a notable inventor based in Seabrook, TX (US). He has made significant contributions to the field of coal liquefaction, holding a total of 2 patents. His work focuses on improving processes that enhance the efficiency and yield of liquefying solid carbonaceous materials.
Latest Patents
One of his latest patents is titled "Donor solvent coal liquefaction with bottoms recycle at elevated pressure." This invention presents an improved process for liquefying solid carbonaceous materials, achieving increased naphtha yields by conducting the liquefaction at pressures ranging from about 1750 to about 2800 psig. The process utilizes a hydrogen-donor solvent containing at least 0.8 wt % donatable hydrogen and operates at temperatures between 700°F and 950°F. The coal-to-bottoms ratio in the feed is maintained between 1:1 and 5:1, while the solvent or diluent to total solids ratio is at least 1.5:1, ideally between 1.6:1 and 3:1. The yield of naphtha boiling range materials increases with pressure, peaking between 2000 and 2500 psig.
Another significant patent is focused on the "Liquefaction of calcium-containing subbituminous coals and coals of lower rank." This process treats calcium-containing subbituminous coal to form insoluble, thermally stable calcium salts that remain within the residue during liquefaction. This innovation helps suppress the formation of scale, primarily calcium carbonate deposits, within the coal liquefaction reactor. The method involves maintaining a solution of a compound characterized by the formula MX, where M is a Group IA metal, in contact with particulate coal feed to impregnate the coal. This allows for liquefaction without significant formation of calcium carbonate on reactor surfaces.
