Abstract

The transient Eulerian two-phase CFD model applying the kinetic theory of granular flow is used to simulate two pilot scale test balances in a fuel reactor of chemical looping combustion with methane as fuel and nickel-based oxygen carrier. The kinetic reaction rate coefficient of Nickel-based oxygen carrier particles is defined based on the measured total methane conversion, and correspondence with the experimental data was found. The bed Sherwood numbers were derived based on the CFD simulations. The derived correspond to the in-literature presented data, and explain the commonly faced problem of obtaining different chemical kinetic coefficients from the TGA and bench-scale fluidized bed reactor tests.
