Title: An Insight into the Inventions of Katsumi Kamegawa
Introduction
Katsumi Kamegawa, an innovative inventor based in Tosu, Japan, has made significant contributions to the field of materials science. With a total of two patents to his name, Kamegawa has focused his research on the development of carbon microparticles utilizing lignin as a raw material.
Latest Patents
Kamegawa's most recent patents illustrate his expertise in producing carbon microparticles. The first patent describes a method for preparing a carbon microparticle from an organic raw material predominantly composed of lignin. This innovative method involves using an aqueous solution with a total lignin concentration of 5% along with sodium hydroxide in a mass proportion of 1:0.5. The process includes spray-drying the solution to create complex microparticles, which are then heat-processed under a nitrogen atmosphere at 600°C for one hour before being cooled. Following this, the microparticles are washed with water and dried, resulting in lightweight hollow carbon microparticles that possess a specific surface area comparable to commercially available activated charcoal.
The second patent focuses on the creation of elastic and ultra-lightweight hollow carbon fine particles. Kamegawa's method includes the formation of fine droplets from a mixed solution containing a water-soluble organic substance and lithium carbonate. By drying these droplets, composite fine particles are prepared, which are subsequently decomposed at temperatures ranging from 500°C to 900°C. This production process highlights Kamegawa's innovative approach to creating advanced materials.
