【Abstract】 Having verified the physical model and simulated the process a priori, the authors have studied the analytical methods for LFO feedstocks and cracking products by using a mass-spectrometer and a gas chromatograph and, then,determined the rate constants involved in the reaction network of LFO catalytic cracking. Cracking reactions were carried out in a fixed fluidized bed reactor using regenerated zeolite catalysts from commercial units. Consequently, parameter estimation has been made by using the improved Gauss-Newton method.Yields predicted by the model show good agreement with experimental data.更多还原
