简介:减少硫的功能的部件--吊楔酸硷的对化合物--并且联系活跃沸石部件被开发为在汽油减少硫内容准备RFCC催化剂DOS。催化剂评估的结果表明了酸硷的对化合物在此开发了的吊楔能提高分子的硫由催化剂加重支持desulfurization反应继续的宏的变换,并且酸硷的对化合物能毫无疑问减少的选择沸石和吊楔的合作行动在汽油的石蜡和硫内容。因此开发的催化剂DOS的重油变换能力更高结合了一个提高的电阻到重金属污染在超过20%在汽油减少硫内容。在西诺佩克·久贾恩格·布朗奇公司的这催化剂的商业应用程序表明了与GRV-C催化剂相比,催化剂DOS获得的油泥浆收益在汽油与一种改进coke选择,增加的全部的液体收益,和一个减少的石蜡内容一起被减少。在汽油/硫在的硫的比率喂油能被20.3m%减少。
