DEVELOPMENT OF AN INVERSE METHOD TO SIMULATE HEAVY METAL VAPORIZATON KINETICS FROM COAL IN A FLUIDIZED BED

摘要：

This study addresses the kinetics of heavy metal vaporization during fluidized bed thermal treatment of coal. Both direct and inverse models were developed in transient conditions. The direct model predicts the time course of the metal concentration in the gas from the vaporization rate profile. The inverse model was developed and validated to predict the metal’s vaporization rate from its concentration in the outlet gas. A method to derive the kinetic law of heavy metal vaporization during fluidized bed thermal treatment of coal from the global model and the experimental measurements is derived and illustrated. A first order law was fitted for the mineral matrix and a second order law was fitted for coal. This method can be applied to any matrix, whatever mineral matrix or organic matrix.
