The kinetics of the prepared ZBDS desulfurizer was experimentally determined under the condition of fixed bed reaction. Kinetic experiment basic conditions: atmospheric pressure reaction, the volume fraction of sulfide 0.2% ~ 0. 04%, the temperature of 20 ~ 60 ℃, desulfurizer average particle size of 0.2mm (60 ~ 80 mesh ), Desulfurization agent added amount of 0. 1g. Under the condition of eliminating the influence of internal and external diffusion, kinetic experimental data under fixed bed reaction conditions were obtained. The experimental data were processed by nonlinear least square method and the empirical dynamic equation was obtained. Residual analysis, deterministic index ρ2 and engineering F test were carried out for the established kinetic model equations. The results show that under the dynamic experimental conditions, the empirical kinetic equation established for the prepared desulfurizer is applicable to engineering
