Title: The Innovative Contributions of Denise Barcellos Da Rocha Monteiro

Introduction

Denise Barcellos Da Rocha Monteiro is a prominent inventor based in Rio de Janeiro, Brazil. She has made significant contributions to the field of refining processes, particularly in the area of highly polyaromatic and nitrogenated charges. Her innovative work has implications for fuel production and optimization.

Latest Patents

Denise holds a patent for a refining process that enhances the production of diesel oil fractions. The patent, titled "Refining process for highly (poly)aromatic and nitrogenated charges," describes a method that includes hydrotreating as the first reaction stage. This is followed by the intermediate separation of gases generated in the hydrotreating section. The process then involves a second reaction stage consisting of moderate hydroconversion or hydrocracking, along with a rectifying and/or fractionating section. This innovative method allows for more flexible fuel production, yielding a diesel oil fraction with higher cetane content and reduced density. The volumetric yield increases by at least 111% relative to the process charge, minimizing yield losses through naphtha overcracking and optimizing hydrogen consumption.
