【摘要】以活性硫H2S为例,研究低浓度时与炼油装置内表面腐蚀产物Fe(OH)3的表面吸附反应过程,考察温度、反应气体相对湿度、Fe(OH)3含水率对吸附反应的影响,旨在为炼油厂抑制因活性硫腐蚀产物引发的自燃事故提供依据。研究结果表明,温度升高,有利于吸附反应,反应气体相对湿度及Fe(OH)3含水率的增加均促进吸附反应。更多还原

【Abstract】 The adsorption reaction between active sulfur-take H2S for example-at a low concentration and Fe(OH)3 the corrosion product on the inner face of refining device was investigated.The effect of temperature,humidity of H2S gas and humidity of Fe(OH)3 was discussed.The results show that with the increasing of temperature,humidity of H2S gas and humidity of Fe(OH)3,the adsorption tendency increases.更多还原
