Abstract Reduction of sodium sulphate to sulphide with hydrogen was studied in a batch fluidized bed reactor. The principal difficulty was fusion of the particles, as some melting was found to be present in the practical range of temperatures. Fusion and agglomeration were minimized by pre‐heating the gas, increasing particle size, and recycling some reduced material. Reaction rates were studied at 649 to 732°C., and an empirical rate equation was fitted to the data. Possible explanations of the rate equation are discussed: changes in reactive surface area, perhaps by a blocking mechanism, appear to be significant.
