Title: Nand K Narain: Innovator in Clean Coal Technology
Introduction
Nand K Narain is a notable inventor based in Bethel Park, PA (US). He has made significant contributions to the field of clean coal technology, holding 2 patents that focus on innovative methods for sulfur removal and the liquefaction of carbonaceous materials. His work aims to enhance the efficiency and environmental sustainability of coal utilization.
Latest Patents
Narain's latest patents include two groundbreaking innovations. The first patent, titled "Sulfur removal and comminution of carbonaceous material," describes a process for producing finely divided, clean coal. This method involves forming a slurry of coarse coal in an aqueous alkali solution and heating it under pressure to critical steam conditions. The supercritical fluid penetrates the coal's porosity, causing it to swell and become thermoplastic. A sudden release of pressure fractures the coal into fine particles while releasing sulfur-containing gases and minerals. The result is a clean coal product that can be recovered from the minerals.
The second patent, "Solvent treatment of coal for improved liquefaction," focuses on increasing liquefaction yield. This is achieved by pretreating a slurry of solid carbonaceous material and a liquid hydrocarbonaceous solvent at temperatures between 200°C and 350°C for a duration of 10 minutes to four hours. This pretreatment enhances the efficiency of the liquefaction process, leading to better yields.
