At the present time, industrial application is being made of fluidized bed roasting for some ore dressing. In this connection, author made an attempt to design a pilot scale furnace roasting for the mixture of barite and anthracite which act as both catalyst and heat source for the operation of the furnace and to study simultaneously on a mathematical consideration regarding some equations associated with the design calculations of the fluidized bed furnace for continuous operation. Calculations of fluidized bed capacity and its dimensions must be effected using equations which take account of the actual distribution of material particles during their stay in the fluidized bed. Especially to design large furnaces one should use the equation, in which account is taken of solid particle diffusion.

The preservative effect of methyl P-hydroxy benzoate was studied as a function of tolc and TiO₂contents. The preservative effect of methyl P-hydroxy benzoate was decreased by the addition of Talc and TiO₂, and this reduction was resulted from adsorption on them. Talc have influence more on decreasing the preservative effects than TiO₂, and the amount of the adsorption of methyl P-hydroxy benzoate on Talc at 20℃ can be represented by the following equation: a = ??
