With a total of 2 patents to his name, Yawata's work has implications for improving the efficiency of hydrocarbon processing.

Latest Patents

Yawata's latest patents focus on catalysts for hydrodemetallization of hydrocarbons containing metallic impurities. The catalysts are created by admixing red mud with alumina or an alumina-containing substance. The process involves adjusting the water content of the admixture, adding an organic binder, kneading, and shaping the mixture into pellets. These pellets are then calcined at temperatures ranging from 600°C to 1,100°C. The resulting catalyst exhibits high compression strength and is capable of achieving a high rate of demetallization while minimizing the yield of low boiling fractions. Notably, the rate of demetallization is enhanced when the process utilizes a hydrogen feed containing hydrogen sulfide.
