| 摘 要： | 研究了Ni基催化剂在CH4/C3H8部分氧化-CO2重整反应中的催化性能和抗积碳性能。采用程序升温表面反应-质谱示踪、透射电子显微镜、热重-差热分析和Raman光谱等方法研究了反应后Ni基催化剂上的积碳物种和形态;采用程序升温氧化和程序升温加氢方法研究了Ni基催化剂上CH4裂解所形成的积碳。研究结果表明,O2可消除不与CO2反应的积碳;降低催化剂表面酸性有利于提高催化剂的抗积碳性能;CH4在Ni基催化剂上裂解形成3种氢含量不同的积碳Cα,Cβ,Cγ,800℃时H2只能消除反应活性较高的C,而O可消除全部积碳;C可形成类石墨碳,导致催化剂失活。

| Abstract: | Carbon deposition on Ni/(CaO-)SiO2 catalysts in reforming of CH4/C3H8 with CO2 and partial oxidation to syngas was studied in a fluidized bed reactor.The morphology of carbon deposition formed on Ni catalyst surface was characterized by means of TG-DTA,Raman spectroscopy and TEM.CO2(O2)-TPSR-MS was used to prove that the carbon deposition on spent Ni/SiO2 catalyst can be completely removed by O2 after reaction with CO2.The chemical reactivity of carbon deposition were investigated by temperature programmed ... |
