Title: Claude Etievant: Innovator in Hydrogen Production
Introduction
Claude Etievant is a notable inventor based in Versailles, France. He has made significant contributions to the field of hydrogen production, holding a total of 8 patents. His work focuses on innovative methods and devices that enhance the efficiency and effectiveness of hydrogen generation.
Latest Patents
One of Etievant's latest patents is a method and device for producing a gas rich in hydrogen through thermal pyrolysis of hydrocarbons. This invention involves a catalyst-free thermal cracking process in a reactor, which pyrolyzes a selected fuel to generate either a hydrogen-rich gas free of carbon monoxide or one that contains carbon monoxide. The gas effluents produced during pyrolysis are utilized as fuel to heat the reactor, achieving the necessary reaction temperature. This method is particularly useful for supplying hydrogen to fuel cells and producing synthesis gas.
Another significant patent by Etievant is related to composite structures of membranes that are selectively permeable to hydrogen. This invention features a filtration bar with an ultra-thin layer made from palladium or silver alloy, which is placed on a permeable, rigid substrate. The design includes a rigid metallic axial structure embedded within the substrate, enhancing its permeability. This technology is especially applicable in hydrogen-producing combustible gas processors.
