Title: Nathalie Marchal: Innovator in Hydrodesulphurization Processes
Introduction
Nathalie Marchal is a prominent inventor based in Saint Genis Laval, France. She has made significant contributions to the field of hydrodesulphurization, holding a total of nine patents. Her innovative approaches have advanced the methods used in refining gasoline and reducing sulfur content.
Latest Patents
One of her latest patents is titled "Process for hydrodesulphurizing gasoline employing a catalyst with controlled porosity." This novel process allows for the selective hydrodesulphurization of gasoline cuts that contain sulfur-containing compounds and olefins. The process utilizes a catalyst made from refractory oxides, such as aluminas, silicas, or magnesia, combined with a group VI metal, preferably molybdenum or tungsten, which may be promoted by a group VIII metal like cobalt or nickel. The catalyst is characterized by a mean pore diameter of more than 22 nm, and the process may involve one or more steps.
Another significant patent is "Process for desulphurizing olefinic gasolines to limit the mercaptans content." This invention focuses on hydrodesulphurizing gasoline with less than 0.1% by weight of sulfur, derived from catalytic cracking or other conversion units. The process includes at least one hydrodesulphurization reactor that uses a bimetallic catalyst, operating under specific conditions of temperature and pressure, while recycling a fraction of the desulphurized gasoline back to the reactor.
Career Highlights
Nathalie has worked with notable organizations such as the Institut Français Du Pétrole and IFP Energies Nouvelles. Her work in these institutions has allowed her to develop and refine her innovative processes in hydrodesulphurization.
