Introduction

Henri Gruhier is a notable inventor based in Chatillon, Bagneux, France. He has made significant contributions to the field of gas purification, holding a total of 10 patents. His innovative approaches have advanced the methods used to purify gases containing harmful substances.

Latest Patents

Among his latest patents is a process for purifying a hydrogen sulfide containing gas. This process involves admixing the gas with oxygen and contacting it with a carbon mass that has a specific surface area greater than 50 m²/g. The carbon mass contains at least one oxide and/or sulfate of iron and/or copper, and operates at temperatures ranging from 20°C to 170°C. The conditions are carefully selected to avoid substantial oxidation of the carbon mass, which is periodically regenerated by heating to 200°C-300°C in the presence of oxygen. Another significant patent involves a process for oxidizing sulfur and sulfur compounds. In this process, a gas containing carbon oxysulfide or carbon disulfide is passed in admixture with oxygen through a catalyst made of a carrier, vanadium oxide, and silver.
