Title: Jacques Persello: Innovator in Silica and Cerium Compounds
Introduction
Jacques Persello is a notable inventor based in Montluel, France. He has made significant contributions to the field of materials science, particularly in the development of silica particulates and cerium compounds. With a total of 14 patents to his name, Persello's work has had a considerable impact on various industrial applications.
Latest Patents
Among his latest patents, Persello has developed precipitated silica particulates with controlled porosity. These particulates possess a BET specific surface area ranging from 20 to 300 m²/g and a CTAB specific surface area ranging from 10 to 200 m²/g. They also have an oil uptake (DBP) ranging from 80 to 400 cm³/100 g, a pore volume of 1 to 10 cm³/g, and a mean pore diameter of 10 to 50 nm. These properties make them well-suited for applications such as paper coating and catalysis. The preparation process involves introducing a silicate and an acid into a colloidal silica dispersion, adjusting the pH, and then separating and drying the silica particulates.
Another significant patent involves a high pH colloidal dispersion of a cerium compound. This invention is characterized by a pH of at least 4 and a conductivity of at most 5 mS/cm. The process for preparing these dispersions includes using a first colloidal dispersion with a lower pH and raising its pH while reducing ionic strength, sometimes adding an organic acid to the starting dispersion.
