Title: Noboru Akita: Innovator in Exhaust Gas Cleaning Technologies
Introduction
Noboru Akita is a prominent inventor based in Kanagawa, Japan, known for his significant contributions to the field of exhaust gas cleaning technologies. With a total of eight patents to his name, Akita has developed innovative methods and apparatuses aimed at improving environmental sustainability in semiconductor manufacturing processes.
Latest Patents
Among his latest patents, Akita has introduced a process and apparatus for cleaning ammonia-containing exhaust gas. This process involves bringing the exhaust gas into contact with an ammonia decomposition catalyst, such as nickel or ruthenium, under heating conditions. This method effectively decomposes most of the ammonia into nitrogen and hydrogen. The resultant mixed gas is then treated with an ammonia adsorbent, like synthetic zeolite, to capture any undecomposed ammonia. The process is designed to efficiently clean exhaust gases without generating useless byproducts or requiring secondary treatment. Another notable patent is a cleaning method for exhaust gas containing ammonia, silanes, and organometallic compounds. This method is particularly useful in the production of compound semiconductors, where the exhaust gas is treated with a cleaning agent that includes soda lime and copper(II) salt, followed by the use of an ammonia decomposition catalyst.
