Title: Hiroshi Kagabu: Innovator in Combustion Flue Gas Treatment
Introduction
Hiroshi Kagabu is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of environmental technology, particularly in the treatment of combustion flue gases. His innovative approach addresses the critical issue of nitrogen oxides emissions, which are harmful pollutants.
Latest Patents
Kagabu holds a patent for a process designed to remove nitrogen oxides from combustion flue gas. This process involves adding ammonia to the flue gas, which contains nitrogen and sulfur oxides. The gas is then brought into contact with a catalyst composed of titanium or tin oxide, or a mixture of both, at temperatures ranging from 150 to 330 degrees Celsius. This method effectively reduces nitrogen oxides to nitrogen and water, while sulfur oxides are deposited as ammonium sulfates on the catalyst's surface. To maintain the catalyst's efficiency, a portion of it is continuously or intermittently removed and treated in a regeneration tower with hot gas at temperatures between 350 and 600 degrees Celsius. This process decomposes the ammonium sulfates into sulfur trioxide and ammonia, allowing for the recycling of ammonia back into the flue gas treatment process.
