随着炼油工业和天然气工业的快速发展,针对SO2排放的环保要求日益严格。对于炼油加工和天然气净化过程所产生的含硫酸性气体,硫磺回收加尾气处理工艺是主要的治理方式,其中TiO2基硫磺回收催化剂逐步得到广泛应用。通过一系列的XPS、XRD、TEM、FT-IR、CO2-T PD、N H3-T PD和吡啶红外分析表征手段,进一步认识到钛基催化剂的表面化学特性,其活性组分为锐钛矿相TiO2,晶粒为纳米级晶粒,具有弱碱性位和中强碱性位。
隨著煉油工業和天然氣工業的快速髮展,針對SO2排放的環保要求日益嚴格。對于煉油加工和天然氣淨化過程所產生的含硫痠性氣體,硫磺迴收加尾氣處理工藝是主要的治理方式,其中TiO2基硫磺迴收催化劑逐步得到廣汎應用。通過一繫列的XPS、XRD、TEM、FT-IR、CO2-T PD、N H3-T PD和吡啶紅外分析錶徵手段,進一步認識到鈦基催化劑的錶麵化學特性,其活性組分為銳鈦礦相TiO2,晶粒為納米級晶粒,具有弱堿性位和中彊堿性位。

With the rapid development of oil refining industry and natural gas industry ,sulfur dioxide emission standard would be increasingly strict .Sulfur recovery and tail gas treatment are the main process for the treatment of sour gas containing hydrogen sulfide from the processing of petroleum and natural gas purification process .TiO2 based sulfur recovery catalyst has been ap-plied widely .By the characterization of XPS ,XRD ,TEM ,FT-IR ,CO2-TPD ,NH3-TPD and pyridine IR ,the results showed that the catalysts were composed of nano-sized anatase phase tita-nium dioxide with weak and strong basic position .
