Title: Marcel Aussillous: Innovator in Oil Processing Technologies

Introduction

Marcel Aussillous is a notable inventor based in Vienne, France, recognized for his contributions to the field of oil processing technologies. With a total of three patents to his name, he has made significant advancements that enhance the efficiency and quality of oil products.

Latest Patents

One of his latest patents is a method for improving the cetane index of gas oil fractions. This innovative process involves transforming a gas oil cut from a conversion process or aromatic crude to enhance its cetane number. The method includes at least one hydrogenation step where the gas oil cut is treated in the presence of hydrogen over a catalyst that comprises an amorphous mineral support, a group VIB metal compound, a non-noble group VIII metal compound, and phosphorous or its compounds. Following this, a hydrocracking step is performed, where the hydrogenated feed is processed over a catalyst with an acidic support and similar metal compounds.

Another significant patent is for a plant designed for purifying spent oil. This invention includes apparatus for dehydration, preferably through atmospheric distillation, which is directly followed by vacuum distillation. This process produces a residue and at least one distilled oil fraction. The vacuum residue is subjected to solvent extraction, and the clarified oil obtained, along with the distilled oil fractions, undergoes finishing hydrotreatment.
