<p>PURPOSE:To provide a desulfurization reagent for high temperature reductive gases and to provide a manufacturing method of the reagent wherein with the reagent the desulfurization speed for a zinc ferrite at low temperature is heightened and the removal limit is sufficiently lowered. CONSTITUTION:The method for manufacturing a desulfurization reagent involves each process of filtering, cleaning, drying, and sintering of a precipitated mixture of zinc and iron obtained by a uniform precipitation method by heating an aqueous solution contains a zinc salt, an iron salt, and a precipitant producing substance. The desulfurization reagent contains 10-100wt.% of a binary oxide containing zinc and iron.</p> |
