The distribution of residence times of solid particles is examined in fluidized beds at steady state with continuous feed and discharge of solids, both for beds consisting of a single particle size and for beds consisting of a wide spectrum of particle sizes. The mean age (residence time in bed) of

โฆ Synopsis
01 Solid fuels (preparation) calculated and discussed. The effects of gasification temperature over different periods on char-CO? gasification reactivity were not the snmc: the reaction was controlled by kinetics below II00 C and controlled by the diffusion at more than I100 C. The higher gasification temperature led to higher reactivity and low,er apparent activation energy.
