Introduction

Kouji Katsumoto is a notable inventor based in Tokyo, Japan, recognized for his contributions to the field of gypsum modification. With a total of two patents to his name, he has made significant advancements in the processing of dihydrate gypsum.

Latest Patents

Kouji Katsumoto's latest patents focus on a process for the continuous modification of dihydrate gypsum. This innovative process involves calcining dihydrate gypsum into hemihydrate gypsum and subsequently recrystallizing it in an aqueous slurry. The aim is to convert the hemihydrate gypsum into modified dihydrate gypsum with a different crystalline form. The process ensures that the aqueous slurry in the recrystallization reaction tank is maintained at a constant temperature under stirring. Furthermore, the feed rate of hemihydrate gypsum and the discharge rate of the recrystallized dihydrate gypsum are controlled to be substantially equal. This method allows for the production of high-purity, modified dihydrate gypsum with large crystals, which is not commonly available.
