Abstract:在小型固定床反应器中考察了纳米H-ZSM-5催化剂(晶粒度为20~50 nm)对丁烯催化裂解制丙烯反应的催化性能,并与两种微米H-ZSM-5催化剂样品(晶粒度分别为1~2和1~6 μm)进行了比较.结果表明,在相同的反应条件下,纳米H-ZSM-5和微米H-ZSM-5催化剂上的初始丁烯转化率及丙烯收率相当,但纳米H-ZSM-5催化剂在反应中的抗积碳失活性能优于微米H-ZSM-5催化剂.在进料质量空速7 h-1,常压和560 ℃的条件下反应,当丁烯转化率和丙烯收率下降50%时,两种微米催化剂上的反应时间仅为28 h左右,而纳米催化剂上的反应时间为120 h左右.积碳分析结果表明,纳米催化剂上的积碳速率明显低于微米催化剂.
