Novel multi-stage aluminium production: part 1 – thermodynamic assessment of carbosulphidation of Al2O3/bauxite using H2S and sodiothermic reduction of Al2S3

“…In 1999, a new method was developed by PowerBall Technologies for producing sodium hydride (NaH) and, by extension, Na using sodium hydroxide (NaOH) and methane (CH 4 ), following reaction in Equation ( 18). A United States Department of Energy (DOE) report found that this method had the potential to reduce the cost of NaH/Na by up to a factor of 10 compared to electrolysis (DiPietro & Skolnik 2000). Hence, the viability of sodiothermic reduction of Al 2 S 3 is predicated on the availability of low-cost Na and low cost of recycling of Na in the process.…”

Experimental Study on Thermal and Catalytic Hydrogen Bromide Oxidation

“…An additional advantage of the BrOx cycle is its flexibility because it can either be set to produce CO 2 -free hydrogen by substituting HBr oxidation with HBr electrolysis or be used for methane functionalization and the production of chemicals …”
