Abstract

A comprehensive simulation tool for the investigation of chemical looping combustion (CLC) process consisting of
two interconnected fluidized bed reactors has been constructed. Dynamic fluidized bed hot-loop model is
implemented into the Matlab/Simulink environment. Semi-empirical correlations are used for the calculation of
reaction kinetics, heat transfer and flow dynamics. The main outputs of the model are the solid circulation rate, the
conversion of the carrier and the gas composition at the reactor exit, the axial profiles of temperature and gas
concentrations, and distribution of solids in the reactor. Various case studies with different boundary conditions,
input parameters and reactor geometries show realistic process behaviour and stable operation.
