Latest Patents

One of Nakano's latest patents is a method for optimizing catalyst loading for the hydrocracking process. This invention focuses on optimizing layered catalytic processes by testing various catalysts with a compound found in the feedstock. The goal is to determine the catalyst's effectiveness in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, thereby improving the overall feedstock quality. In preferred embodiments, the method involves determining the Double Bond Equivalence of the feedstock and molecule, allowing for the pre-selection of catalysts based on their compatibility with materials of this DBE value. Additionally, the layered catalysts include a demetallization catalyst used prior to hydrocracking, with the test feedstock containing 500 ppmw or less asphaltenes.

Another notable patent by Nakano is related to a hydrocracking catalyst for hydrocarbon oil. This invention comprises a support containing a framework-substituted zeolite-1, where zirconium and/or hafnium atoms are part of the framework of an ultrastable Y-type zeolite. The catalyst is designed to facilitate the diffusion of heavy hydrocarbon oils into mesopores, improving cracking activity and yielding higher middle distillate outputs compared to traditional catalysts.
