Introduction
Joseph V Nguyen is a prominent inventor based in Albany, CA (US). He has made significant contributions to the field of hydroprocessing catalysts, holding a total of 9 patents. His work focuses on improving methods for upgrading heavy oil feedstock, which is crucial for the energy industry.
Latest Patents
Nguyen's latest patents include innovative methods for preparing slurry catalysts. One of his notable inventions involves a process for preparing an improved slurry catalyst for the upgrade of heavy oil feedstock. This method includes sulfiding a metal precursor solution with a sulfiding agent to form a sulfided Group VIB catalyst precursor. The process ensures that the metal precursor solution has a pH of at least 4 and a concentration of less than 10 wt. % of primary metal in solution. The resulting slurry catalyst composition boasts a BET total surface area of at least 100 m/g, a total pore volume of at least 0.5 cc/g, and a polymodal pore distribution with at least 80% of pore sizes ranging from 5 to 2,000 Angstroms in diameter.
Another significant patent by Nguyen describes an improved process for preparing a slurry catalyst using high shear mixing. This method generates an emulsion containing droplets of metal precursor in oil, with droplet sizes ranging from 0.1 to 300 µm. The emulsion is sulfided with a sulfiding agent or in-situ in a heavy oil feedstock, ensuring that the heavy oil feedstock generates the necessary sulfiding source for the sulfidation process.
