用固定床流动反应装置考察了负载于不同载体上的催化剂的活性和抗积炭性能；用色谱法测定了催化剂上的积炭量。用ＴＰＤ和ＸＰＳ研究了催化剂的表面酸碱性。并与催化剂的抗积炭性能相关联。发现用ＳｉＯ２作载体的催化剂抗积炭性能差，在其中加入碱土金属助剂有利于抗积炭，以α－Ａｌ２Ｏ３作载体的催化剂抗积炭性能较好，但在其中加入碱土金属助剂却会导致催化剂严重粉化，反而对抗积炭不利。并讨论了催化剂粉化的原因。 The immobilized bed flow reactor was used to investigate the activity and anti-carbon deposition of the catalyst supported on different supports. The amount of carbon deposition on the catalyst was determined by chromatography. The surface acidity and basicity of the catalyst were investigated by TPD and XPS. And is associated with the catalyst’s resistance to carbon deposition. It is found that the catalyst with SiO2 as carrier has poor anti-carbon deposition performance, and the addition of alkaline earth metal additives is good for anti-carbon deposition. The catalysts with α-Al2O3 as carrier have good anti-carbon deposition performance, but alkaline earth metal additives Will lead to serious catalyst powder, but against carbon deposition adverse. The reason for catalyst chalking is also discussed.
