Latest Patents

Hassan Hannache holds a patent for a method of producing sulfur from phosphogypsum. The objective of this invention is to create a new process that efficiently converts phosphogypsum into sulfur. The process involves mixing phosphogypsum with a source of carbon and hydrogen, forming a slurry. This source can be a natural or synthetic organic polymer, such as biomass, used tires, plastics, kerogen, or tars. The mixture undergoes heat treatment at temperatures between 100 to 150° C to evaporate the mixing water. Subsequently, the product is subjected to a second heat treatment at temperatures ranging from 550 to 900° C under a neutral or partially oxidizing atmosphere. The generated gases are then bubbled through deionized water, sodium hypochlorite solution, or a basic aqueous solution, allowing for the trapping of organosulfur molecules and the precipitation of sulfur S8. Non-entrapped gases are recovered to extract volatile sulfur products.

Career Highlights

Hassan has worked at notable institutions, including Université Mohammed VI Polytechnique and Université Hassan I de Settat. His experience in these academic environments has allowed him to refine his research and contribute to advancements in chemical processes.
