Title: Gilbert Roche: Innovator in Membrane Technology
Introduction
Gilbert Roche is a notable inventor based in La Barriere, France. He has made significant contributions to the field of membrane technology, holding a total of 2 patents. His work focuses on the development of advanced materials for various applications, particularly in the area of water treatment and hydrocarbon processing.
Latest Patents
Roche's latest patents include an organomineral semipermeable membrane and its production process. This invention relates to semipermeable organomineral membranes that are usable in reverse osmosis. The membrane comprises a porous inorganic material support coated with a vinylidene fluoride polymer or copolymer-based organic layer. This layer incorporates functional groups that provide the membrane with permeability to water or other solvents. The porous inorganic material support is preferably made from a macroporous substrate coated with a microporous layer, which can be produced from a single or mixed metal oxide or hydroxide. Additionally, the organic layer can consist of polyvinylidene fluoride grafted with an appropriate monomer, such as styrene, which includes functional groups that give it selective permeability, such as hydrophilic groups like sulphonic groups.
Another significant patent involves a method for the liquid phase hydrotreatment of heavy hydrocarbons. This hydrotreatment method, which can include hydroviscoreduction or hydrodesulfurization, involves reacting hydrocarbons with hydrogen in contact with a finely dispersed catalyst in the liquid phase. To separate the product from the catalyst, the effluent, which is freed from its accompanying free gas, is passed along and in contact with the upstream wall of a porous inorganic membrane. The oil that has not been filtered contains a concentrate of catalyst and is recycled back to the hydrotreatment reactor, while the filtered oil constitutes the final product of the method.
Career Highlights
Throughout his career, Gilbert Roche has worked with prominent organizations such as the Commissariat à l'Énergie Atomique et aux Énergies Alternatives and the Institut Français du Pétrole.
