一、前言氧化铁脱硫剂是一种高效脱硫剂,在常温下可将硫化氢及硫醇等迅速脱除干净,在国内外已被广泛用于城市煤气及合成氨等工业。国外近年来对该脱硫剂进行了许多改进,而国内自前仍采用以生铁屑与锯末拌合的常温氧化铁脱硫剂,存在工艺落后、设备庞大、效率不高、接触时间长等缺点。为了改进现有工艺,我们以太原化工厂硫酸车间的硫铁矿灰为主要原料进行了新型脱硫剂的研制工作。经过努力,最后研制成功一种条形氧化铁脱硫剂,取名为“TG型常温氧化铁脱硫剂(简称TG型脱硫剂)”。通过小试及中试考核表明,TG型脱硫剂具有价廉易制、操作 相似文献

A new reaction for the halogenation of thiophene in the coking benzene was investigated. The method was designed to occur in a water-benzene two-phase mixtures solution containing both the permanganate and the chloride. A partial of thiophene will react with chlorine to generate the 2-chlorothiophene or 2,5-dichlorothiophene. The total sulfur and the thiophene contents in the benzene were determined by micro coulometer and GC-FPD respectively. The chloro-thiophenes produced were characterized by GCMS analysis. The preliminary results show that the thiophene in the benzene can not be oxidized by alone potassium permanganate solution even at pH 2—3. When the chlorides were used as the co-reactant the thiophene can be converted to chloro-thiophene. The process could be explained as follow: the chloride was oxidized by permanganate to generate chlorine in the suitable acidic solution, then the chlorine produced react immediately with thiophene to form chloro-thiophenes. The thiophene in the coking benzene could be completely converted by using the new method if the suitable reaction conditions are selected such as the pH value of aqueous solution and the molar concentration of both the permanganate and chloride. 相似文献
