The dynamic for the preparation of desulfurizing agent ZBDS was studied at the fixed bed reactor.The basic conditions conducted at the dynamic experimental research were:the pressure was atmospheric,the volumn fraction of sulfur compounds was 0.02%～0.04%,the reaction temperature was 20～60 ℃,the average size of ZBDS was 0.21 nm(60～80 mesh),and the amount of ZBDS used in the dynamic experiment was 0.1g.The experimental dynamic equation was obtained by nonlinear regression program,which computed weighted least squires of the defined objects function.The established dynamic equation was engineering in point based on the engineering proving.
