Title: Asim B Ray: Innovator in Coal Desulfurization Technologies
Introduction
Asim B Ray is a notable inventor based in Bridgewater, NJ (US), recognized for his contributions to the field of coal desulfurization. With a total of three patents to his name, Ray has made significant strides in developing innovative processes that enhance the environmental sustainability of coal usage.
Latest Patents
Ray's latest patents include groundbreaking technologies aimed at reducing sulfur content in coal. One of his notable inventions is the "Electron Beam Coal Desulfurization," which utilizes electron beam irradiation to convert both organic and inorganic sulfur compounds in coal into removable forms. These forms include elemental sulfur, gaseous compounds, and water-soluble compounds. The process involves pulverizing and slurrying coal, which is then introduced into an electron beam reaction chamber where the conversion reactions occur. This method not only effectively removes sulfur but also inherently results in coal dechlorination.
Another significant patent is the "Process for Desulfurization of Coal," where coal is oxidized by nitrogen oxides (NO.sub.x) in the presence of a liquid that is soluble in NO.sub.x. The oxidized sulfur species are subsequently removed by washing with water and dilute sulfuric acid. Remarkably, NO.sub.x is not consumed during the process and is recycled, allowing for the removal of more than 70% of sulfur in coal.
