Title: Innovations of Hidetsugu Fukuyama in Catalyst Technology

Introduction

Hidetsugu Fukuyama is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of catalyst technology, particularly in the refining of heavy crude oil. With a total of 3 patents to his name, Fukuyama's work has had a substantial impact on the petroleum industry.

Latest Patents

Fukuyama's latest patents include a carbon-supported catalyst for the demetallation of heavy crude oil and residue. This innovative catalyst features a high surface area and pore volume, incorporating molybdenum, a non-noble Group VIII metal, and phosphorus. The catalyst is designed for hydrometallization, containing about 6 to 15 wt % molybdenum as MoO, and 1 to 6 wt % cobalt or nickel as CoO or NiO. One of its key characteristics is that over 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 due to the presence of more dispersed active metals. Long-term studies indicate that the catalyst, which has only molybdenum supported on activated carbon, maintains good stability over time and exhibits a very high metal retention capacity.

Another significant patent involves a hydrocracking catalyst and method for hydrocracking heavy oil. This process efficiently removes asphaltene and impurities, including heavy metals like nickel and vanadium, from heavy oil using activated carbon. The invention provides a hydrocracking catalyst that comprises activated carbon extrudate as a carrier, activated with steam, and features a high distribution of pores with sizes ranging from 20 to 200 nm.
