摘要: Abstract A new method to evaluate horizontal dispersion of solids in bubbling fluidized beds is proposed: a carbon-loaded bed material prepared using the capacitance effect (volatile matter captured by porous particles) used as tracer. The tracer particles are identical remainder material, except for carbon-loading few weight percent. extent solid evaluated measuring concentration profile CO, which formed reaction carbon tracers with CO2 fluidizing gas. Transient change CO measured freeboard and experimental results compared theoretically calculated one-dimensional diffusion solids. Thereby, coefficient determined. agree obtained from literature.
