Title: Innovations of James W Clarke in Coal Extraction

Introduction

James W Clarke is an accomplished inventor based in Tewkesbury, GB. He has made significant contributions to the field of coal extraction, holding a total of 3 patents. His innovative approaches have the potential to enhance the efficiency of coal extraction processes.

Latest Patents

One of Clarke's latest patents involves a method for coal extraction using a mixed solvent that includes both a substantially aromatic component and a substantially naphthenic component. This process operates at temperatures ranging from 400 to 500 degrees Celsius. Although neither component is particularly effective as a solvent for coal on its own, the combination provides greater flexibility and efficiency in the extraction process. Another notable patent focuses on improving the filtration of coal extracts obtained from hydrogenative liquid extraction. By conducting the extraction at temperatures above 420 degrees Celsius and fractionating the resulting extract with a cut point between 200 and 300 degrees Celsius, the process allows for the removal of low boiling materials. The final product is filtered to yield a filtrate containing less than 0.1% by weight of mineral matter.
