Title: Shirou Moroi: Innovator in Nitrogen Trifluoride Production
Introduction
Shirou Moroi is a notable inventor based in Yamaguchi, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of nitrogen trifluoride and graphite fluoride. With a total of 3 patents to his name, Moroi's work has implications for various industrial applications.
Latest Patents
One of Moroi's latest patents is a method for producing nitrogen trifluoride by gas-solid reaction. This innovative method involves several steps, including the use of a packed-bed-type vessel filled with a particulate solid of an ammonium complex of a metal fluoride. The process allows a fluorine-containing gas to flow upwardly through the vessel, reacting with the particulate solid to produce a reaction gas containing nitrogen trifluoride. This method significantly improves the yield of nitrogen trifluoride.
Another notable patent is the method of producing ultrafine particles of graphite fluoride. In this process, graphite fluoride in the form of submicron particles is obtained at high yield by using acetylene black as the carbon material to be fluorinated with fluorine gas. This method demonstrates that using any other type of carbon black does not yield comparable results. The graphite fluoride produced from acetylene black is noted for its superior dispersibility.
