Abstract: To investigate the formation reason of by-products in tannin extract desulfurization, the kinetics of the chemical oxidation of aqueous HS- solutions have been studied in a continuous bubbling reactor. The results show that the reaction rate increased as the initial concentration of HS- increased, and the air velocity accelerated, and reaction temperature rose. The rate equation is -[image omitted] = 1.13 exp(-25622.71/RT)CHS-. By theoretical analysis and experimental research, it is discovered that the oxidation products of HS- are mainly S2O32- and not sulfur. In addition, some suggestions were put forward to reduce by-products. [ABSTRACT FROM AUTHOR]
