“A fluidized bed gas-solid reactor was designed and tested in which most of the fluidization energy is provided by a helical stirrer, with gas being used primarily as a reactant. The bulk gas in which the particles are suspended is practically constant in composition except for the area immediately adjacent to the gas inlet. The reactor is capable of withstanding temperatures up to at least 800°C and can be used with a wide range of flow rates. It is intended primarily as a laboratory tool, with the potential to be scaled up to multikilogram size.

The reactoor is a useful tool for the study of equilibrium reactions in the gas-starved condition. It may be useful for the study of gas-solid kinetics. A major advantage is that only a small amount of solid material (around 200 g) is needed.

A variety of gas-solid particulate reactions were studied. A stirring speed of 180 rpm and gas flow rate of about 150 ml/min were found to be appropriate in most situations. A wide range of particle sizes was examined (35 to 200 mesh). Free flowing materials are preferred. The reactor was primarily used for roasting sulfides but some experiments were conducted on the selective sulfation of mixed oxides”--Abstract, page ii.
