【摘要】 以用于异丙苯合成的中试失活ＦＸ－ ０１ 催化剂为研究对象，在不同温度下进行烧炭再生，并对再生催化剂的活性、酸性、炭含量、比表面积进行表征和测试，发现失活ＦＸ－ ０１ 催化剂在４００ ～４５０ ℃时其活性、酸性及比表面积基本得以恢复。继续升高温度，由于水蒸汽对沸石骨架的脱铝作用，对催化剂的再生将起负面的影响。更多还原

【Abstract】 The properties of coked and regenerated FX-01 catalyst by air steam used in the synthesis of isopropylbenzene were investigated by using TPD,TPO and adsorption/desorption methods.The activity,acidity,content of coke and inner surface area are recoverd under 400～450 ℃.Because higher temperature will remove some Al from framework of β zeolite by steam,the temperature of regenerated should not surpass 500 ℃.更多还原
