✦ Synopsis


time is the same as that corresponding to pore diffusion control (Equation ( )).

If the evolution of surface area can be described by: S/S,=(l-f)"3 (6) the resulting equation for the conversion coincides with that for film-diffusion control (Equation ( )). Therefore, it is concluded that much care should be taken when the control under which a gas-solid reaction takes place has to be established. Together with verification of adequate correlation of the data with proposed model equations, tests for the determination of the absence of the other resistances should be carried out.

The combustion rates of three different sized fractions of char from a swelling bituminous coal have been measured in the temperature range 800 to 1700 K. The mass-median sizes of the fractions were 70, 35 and 18 pm. For each fraction the combustion rate was less than the limiting rate set by diffus
