Title: Innovations of Harry A. Marshall in Methanol Production
Introduction
Harry A. Marshall is a notable inventor based in Madison, NJ (US), recognized for his contributions to the field of chemical engineering, particularly in the production of methanol. With a total of 6 patents to his name, Marshall has made significant strides in developing efficient methods for synthesizing methanol from carbonaceous materials.
Latest Patents
One of Marshall's latest patents focuses on the production of methanol via catalytic coal gasification. This innovative process involves gasifying a carbonaceous feed material with steam in the presence of a carbon-alkali metal catalyst, along with added hydrogen and carbon monoxide. The reaction occurs at temperatures between approximately 1000°F and 1500°F and at pressures exceeding 100 psia. The resulting raw product gas comprises methane, steam, carbon dioxide, carbon monoxide, hydrogen, and hydrogen sulfide. The process includes several steps, such as withdrawing the raw product gas, treating it to remove steam and particulates, and separating the treated gas into methane-rich and carbon monoxide-hydrogen streams. The methane-rich gas is then passed to a steam reforming furnace, while the carbon monoxide-hydrogen stream is directed to a methanol synthesis reactor, where methanol is produced.
