Title: Kenji Nakamura: Innovator in Hydrofining Technology
Introduction
Kenji Nakamura is a prominent inventor based in Toda, Japan. He has made significant contributions to the field of hydrofining technology, holding a total of 2 patents. His work focuses on developing catalysts and processes that enhance the efficiency of heavy oil hydrorefining.
Latest Patents
Nakamura's latest patents include a hydrofining catalyst and a hydrofining process. The heavy oil hydrorefining catalyst he developed features a total volume of pores with a diameter of 60 nm or less of at least 0.5 mL/g. The pore diameter distribution is broad, ranging from 8 to 30 nm. This catalyst exhibits excellent desulfurization and demetalization characteristics, maintaining performance over extended periods. When utilized in a hydrorefining apparatus with multiple catalyst layers, it can operate stably at higher temperatures without compromising desulfurization performance, thereby enhancing demetalization characteristics.
Another patent involves a catalyst support and reactor for hydrogenation reactions. The catalyst carrier is composed of a refractory inorganic oxide and has a rotationally symmetrical shape with a hollow portion, resembling a doughnut. This design prevents granular substances from causing catalyst plugging, extending the catalyst's life due to low differential pressure increases even when granular substances accumulate. Additionally, it prevents channeling of the reaction fluid, and a hydrogenation reactor is provided with a fixed bed packed with this catalyst.
