Patent number: 12116273Abstract: The objective of the invention is the development of a new process for producing sulfur from phosphogypsum. During this process, the phosphogypsum is mixed with a source of carbon and hydrogen forming a slurry after mixing. This source of carbon and hydrogen is a natural or synthetic organic polymer, as an example that is not limiting, biomass, used tires or plastic, kerogen or tars. The granules undergo a heat treatment (100 to 150° C.) to evaporate the mixing water. The product obtained undergoes a heat treatment (550 to 900° C.) under a neutral atmosphere and/or partially oxidizing. The generated gases are bubbled in deionized water, sodium hypochlorite solution or a basic aqueous solution which allows the trapping, among others, of organosulfur molecules and the precipitation of sulfur S8. Non-entrapped gases are recovered to extract volatile sulfur products.Type: GrantFiled: December 9, 2019Date of Patent: October 15, 2024Assignees: Universite Mohammed VI Polytechnique, Universite Hassan 1ER De Settat, Universite Hassan II De CasablancaInventors: Younes Alami Hamedane, Hassan Hannache, Bouchaib Manoun, Youssef Tamraoui, Mina Oumam
