Title: Pierre Mathieu: Innovator in Gas Desulphurization

Introduction

Pierre Mathieu is a notable inventor based in Orthez, France. He has made significant contributions to the field of gas desulphurization, holding a total of 2 patents. His work focuses on improving processes that reduce harmful emissions, particularly those containing sulfur compounds.

Latest Patents

One of Pierre Mathieu's latest patents is a process and installation for desulphurizing gases containing SO₂. This innovative method involves the absorption of sulfur-containing compounds using absorbents based on alumina that are free of alkaline substances. The absorption occurs at temperatures ranging from 100°C to 400°C. After the absorbent is loaded with these compounds in the form of sulfates, it is heated with a reducing gas, such as H₂S, at temperatures between 250°C and 450°C. This process allows for the separation of elementary sulfur from the absorbent, which can then be reused in subsequent operations. Another significant patent involves the Claus process for sulfur production, which is enhanced by the use of a deoxidation catalyst prior to the conventional Claus oxide catalyst.
