据有关资料报道采用螯合铁湿式氧化法脱硫的研究始于六十年代,二十年来,美国、英国、日本,捷克等国家已发表了许多专利报导.国内的一些高校也曾作过大量的研究工作,并推广应用.这个方法存在的问题是螯合铁在碱性介质中脱硫有明显的降解现象,至今对降解问题讲不清楚,因而影响继续推广使用.本文用 DEA 有机醇胺代替无机碱,这不但能够防止 Fe—EDTA 催化剂的降解并能净化 According to the data reported that the use of chelated iron wet oxidation desulfurization began in the sixties, twenty years, the United States, Britain, Japan, the Czech Republic and other countries have published a number of patent reports. Some colleges and universities have also made a large number of Research and promote the use of this method is the existence of the problem chelated iron desulfurization in alkaline medium obvious degradation phenomenon, so far the degradation of the problem is not clear, and thus continue to promote the use of this article DEA organic alcohol amine instead of inorganic Alkali, which not only can prevent the degradation of Fe-EDTA catalyst and purify it
