摘要/Abstract

摘要： 针对湿法氧化法脱除硫化氢气体可以回收硫磺副产物，并且脱硫剂可以循环使用的特点，以铁盐在低共熔溶剂中作为脱除硫化氢气体的氧化剂，考察了反应条件对脱硫率的影响。结果表明：合适的Fe(NO3)3?9H2O浓度是保证高脱硫率的必要条件，离子液体体系是影响脱硫率的主要因素；在一定的低共熔溶剂条件下，脱硫率主要受硫化氢气体进口流量的影响。反应产物为单斜相硫磺。

Abstract: Wet oxidation method can remove hydrogen sulfide and recover sulfur by-product and the desulfurizer can be recycled. The ferric salt in deep eutectic solvent was used as oxidant for removing hydrogen sulfide. The effect of different reaction conditions on the desulfurization is investigated. The results show that the suitable concentration of Fe(NO3)3?9H2O is the necessary requirement for high efficiency desulfurization, and the ionic liquid system is the main factor influencing the desulphurization rate. Under the conditions of certain eutectic solvent, the desulfurization efficiency is mainly affected by inlet flow rate of hydrogen sulfide gas. The product is of monoclinic sulfur.
