Abstract: A process for the production of chlorates and derivative chemicals from ammonium perchlorate as a starting material. Ammonia is produced in a first step wherein a metal hydroxide is reacted with ammonium perchlorate to produce ammonia and a metal perchlorate. If the metal hydroxide used is sodium hydroxide, sodium perchlorate is formed. The ammonia generated is recovered and sent to a reformer to produce hydrogen which is used to fuel a fuel cell that generates water and electrical energy to run an electrochemical reactor where the metal perchlorate is converted to a metal chlorate and derivative chemicals.
Abstract: Production of methanol from a stream of crude glycerol. The crude glycerol is preferably a side product (waste product) that results from the production of biodiesel from vegetable oils and animal fats. The crude glycerol stream is combined with superheated steam and oxygen to produce a synthesis gas that is then passed to a methanol synthesis reaction zone to produce methanol.
