Guy Barre

Title: Guy Barre: Innovator in Catalytic Processes

Introduction

Guy Barre is a notable inventor based in Grand Couronne, France. He has made significant contributions to the field of catalytic processes, holding a total of 7 patents. His work primarily focuses on improving the efficiency and effectiveness of hydrocarbon processing.

Latest Patents

Among his latest patents is a groundbreaking catalytic dewaxing process. This process involves the catalytic dewaxing of a hydrocarbon oil feed that includes waxy molecules and more than 500 ppmw of sulfur or sulfur-containing compounds. The method entails contacting the oil feed under catalytic dewaxing conditions with a catalyst composition that comprises at least a hydrogenation component, dealuminated aluminosilicate zeolite crystallites, and a low acidity refractory oxide binder material that is essentially free of alumina.

Another significant patent involves a process wherein a hydrocarbon feedstock is contacted with a catalyst. This catalyst comprises from 0.1 to 15% by weight of a noble metal selected from one or more of platinum, palladium, and iridium, along with 2 to 40% by weight of manganese and/or rhenium supported on an acidic carrier. These weight percentages indicate the amount of metal based on the total weight of the carrier. The use of this catalyst is crucial in a process where a hydrocarbon feedstock containing aromatic compounds is contacted with the catalyst at elevated temperature and pressure in the presence of hydrogen. Additionally, he has developed a process for the preparation of this catalyst, which includes incorporating the catalytically active metals into the carrier followed by drying and calcining.
