A CORRELATION TO THE SOLUTION OF THE 2-PHASE DISPERSION MODEL

A correlation to the solution of the two-phase dispersion model has be en developed for gas-solid fluidized bed reactors operating in the bub bling regime. An analytical solution was obtained for fractional gas c onversion by using an exponential function to characterize the dense p hase gas concentration profile. The coefficient of the exponential fun ction was found to depend on gas axial dispersion and, in order to det ermine this parameter, a Peclet number correlation was developed. Mode l predicted gas conversions were in excellent agreement with experimen tal conversions for a variety of fluidized bed reaction data over a co nversion range from 2.5 to 99%.
