Title: **Alain Adjemian: Innovator in Pure Alumina Production**
Introduction
Alain Adjemian is a prominent inventor based in Aix-en-Provence, France, known for his significant contributions to the field of materials science, particularly in the production of pure alumina. With a total of five patents to his name, his work has paved the way for advancements in efficient alumina extraction methods.
Latest Patents
Alain Adjemian's latest innovations include two pivotal patents that enhance the process for obtaining pure alumina. The first patent describes a continuous process that employs a chlorosulphuric attack on calcined aluminous ores containing impurities. This method involves several critical steps: concentration of the resultant liquor, treatment using sulphuric acid, and chlorination to precipitate hexahydrated aluminum chloride. Subsequent steps include the pyrohydrolysis of the precipitate to yield pure alumina while recycling hydrochloric acid, along with a degassing process for chlorosulphuric liquor to eliminate impurities.
The second patent presents a cyclic process, focusing on hydrochloric acid attacks on silico-aluminous materials to achieve very pure alumina. This innovative process consists of a two-stage operation, where the first stage precipitates up to 75% of the alumina as hexahydrated aluminum chloride, followed by decomposition through heating. The second stage involves further treatment with HCl gas to recover dissolved Al2O3, allowing for recycled processing and effective impurity removal using recycled sulphuric liquor.
Career Highlights
Alain's career includes noteworthy tenures at leading organizations in the aluminum industry, notably Aluminum Pechiney. His experiences in these companies have been instrumental in shaping his innovative approaches in alumina production. His passion for improving industrial processes has consistently driven his research and development efforts.
