Title: Ichiro Tokumitsu: Innovator in Pyrolysis and Polycarbonate Production

Introduction

Ichiro Tokumitsu is a notable inventor based in Tokuyama, Japan. He has made significant contributions to the fields of pyrolysis gas treatment and polycarbonate oligomer production. With a total of 3 patents to his name, Tokumitsu's work has had a considerable impact on industrial processes.

Latest Patents

One of his latest patents is an "Apparatus for quenching pyrolysis gas." This innovative apparatus allows for the rapid cooling of pyrolysis gas derived from hydrocarbons. It simplifies the decoking process of pyrolysis furnaces and significantly extends the life of the apparatus. The design includes a multi-tubular pyrolysis furnace where the upper outlet of each cracking tube connects directly to vertical introducing pipes. These pipes have a larger diameter and are positioned above the upper outlet, enhancing the cooling efficiency. Additionally, cooling pipes with closed lower ends are inserted into the introducing pipes, allowing for effective cooling medium flow.

Another significant patent is the "Method for producing a polycarbonate oligomer." This method enables the preparation of polycarbonate oligomers with uniform qualities. It involves reacting an aqueous alkaline solution of 2,2-(4,4'-dihydroxydiphenyl) propane with phosgene in the presence of methylene chloride. A key aspect of this method is the use of an inert gas in a specific molar percentage relative to the phosgene, which contributes to the quality of the final product.
