Title: Innovations by Raymond A DeWall
Introduction
Raymond A DeWall is a notable inventor based in Grand Forks, ND (US). He has made significant contributions to the field of hydrothermal treatment and coal processing, holding two patents that enhance the characteristics of slurry fuels and low-rank coal agglomerates.
Latest Patents
His latest patents include "Methods to enhance the characteristics of hydrothermally prepared slurry" and "Low-rank coal oil agglomeration product and process." The first patent focuses on improving the flow behavior and stability of hydrothermally treated slurry fuels. A mechanical high-shear dispersion and homogenization device is utilized to shear the slurry fuel. Improvements also involve blending carbonaceous material with a form of coal to reduce or eliminate flocculation, while maintaining the hydrothermal treatment temperature between approximately 300 to 350 degrees Celsius. The second patent describes a process for producing a low ash and relatively water-free agglomerate from low-rank coal, enhancing its heating value and hardness. This process includes treating the coal under high shear conditions for ash reduction and surface modification, followed by contacting it with bridging and binding oils to form agglomerates of selected size.
