水蒸气作为催化剂处理H_2S气体的试验研究

STUDY ON THE INFLUENCE OF STEAM ON THE SPEED OF SO_2 REACT WITH H_2S

目前国内外对较高浓度的H2S的治理主要是使用克劳斯法,但该方法虽几经改进,反应也要在200~400℃的条件下才能进行,治理费用较高。本研究采用水蒸气作催化剂,改变了SO2+2H2S=3S+2H2O的反应历程,使该反应在常温下就有显著的反应速度,在反应温度为50~60℃时,硫的转化率可达到90%左右,使H2S的污染治理技术取得了历史性突破。

At present,Claus process is mainly used for treating High concentrations of H2 S in the world.However,the reaction by this process must be realize on the condition of 200 ~ 400 ℃,whose cost is very high.This study use the steam as catalyst,which make the reaction of SO2+ 2H2 S = 3S + 2H2 O having an obvious reaction speed at room temperature.When the temperature is 50 ~ 60 ℃,the conversion rate of sulfur can reach 90%.That has achieved a historic breakthrough in the field of pollution control technology of H2 S.
