Title: Satoshi Terai: Innovator in Hydrocracking Technology

Introduction

Satoshi Terai is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of petroleum refining, particularly in the development of catalysts for hydrocracking heavy oil. With a total of 4 patents to his name, Terai's work has had a substantial impact on the industry.

Latest Patents

One of Terai's latest patents is a carbon-supported catalyst for the demetallation of heavy crude oil and residue. This catalyst features a high surface area and pore volume, containing molybdenum, a non-noble Group VIII metal, and phosphorus. The catalyst is designed for hydrometallization of heavy crude oil and residue, with a composition that includes about 6 to 15 wt % molybdenum as MoO, and about 1 to 6 wt % cobalt or nickel as CoO or NiO. A key characteristic of this catalyst is that at least 20 percent of its pores have a diameter ranging from 200 to 2000 Angstroms. Additionally, the catalyst prepared with a chelating agent demonstrates higher hydrodesulfurization activity, indicating a more dispersed presence of active metals. Long run activity studies have shown that a catalyst with only molybdenum supported on activated carbon maintains good stability over time and exhibits a very high metal retention capacity.

Another significant patent by Terai is related to a hydrocracking catalyst and method for hydrocracking heavy oil. This process efficiently removes asphaltene and impurities, including heavy metals such as nickel and vanadium, from heavy oil using activated carbon. This innovation helps prevent the reduction in catalyst activity and the formation of coke caused by these impurities. The hydrocracking catalyst comprises activated carbon extrudate as a carrier, which is activated with steam and features a high distribution of pores with sizes ranging from 20 to 200 nm.
