在管式反应器上，考察了页岩油泥在不同催化剂( Al2 O3、K2 CO3、Fe2 O3)及比例(质量比为13、15、110)下的热解行为，着重研究了催化剂对产油率和热解油馏程的影响。结果表明：油泥催化热解效果良好，碳酸钾在15时，产油率达到44.08%，氧化铝在13时，产油率达到45.42%，与无催化剂相比，分别提高了28.97%和32.89%。对馏程的促进方面，氧化铁表现突出，在15和110时，均使得重、柴油含量下降，汽油含量上涨。催化热解是按碳正离子机理进行的，重质油发生裂化反应，烷烃出现聚合反应，均提高轻质油的产量。

Aimed at studying on the relationship between catalysts and oil yield and boiling ranges,pyrolysis of oil shale sludge was carried out in a tubular electric furnace with different catalysts ( Al2 O3、K2 CO3 and Fe2 O3 ) and mixing ratios ( 1 3、1 5、1 10 ) . The results showed that the effect of catalytic pyrolysis of oil shale sludge was good,the addition of K2 CO3 at 1:5 leaded to the increase of the total oil yield up to 44. 08%, when the mass fraction of Al2 O3 in oil sludge was 33%,the yield of shale oil increased to 45. 42%. Compared with Catalyst-free,the oil yield respectively increased by 28. 97% and 32. 89%. In the aspect of catalysts im-proving the quality of shale oil,Fe2 O3 appeared stronger catalytic role than other metal oxides. When the mass fraction of Fe2 O3 in oil shale sludge was 10~20%,the yield of gasoline increased sharply. Catalytic pyrolysis is abide by carbocations mechanism. Both the cracking of heavy oil and polymerization of paraffin could im-prove the yield of gasolene.
