Abstract

Dachengzi oil shale samples were retorted over Fe₂O₃ and CaCO₃ in a small reactor to evaluate their catalytic effects on oil yield and quality. The results indicated two catalysts enhanced kerogen reactivity and secondary reactions of pyrolysis products, which slightly improved the shale oil yield but significantly upgraded pyrolysis volatiles. Adding catalysts facilitated the cracking reactions of heteroatomic compounds, increased the selectivity of aromatic hydrocarbons and promoted olefin aromatization. Fe₂O₃ produced shale oil with lower 1-olefins, aromatics, N and S contents, which more obviously catalyzed kerogen decomposition to improve the heavy fractions and asphaltenes. The total n-paraffins content was about twice that of total 1-olefins in the derived shale oils which mainly contained bicyclic and tricyclic aromatic compounds. Using catalysts increased the total n-paraffins content and PACs with high ring numbers. Catalytic cracking of naphthalenes more easily occurred over Fe₂O₃. Fe₂O₃ was more favorable to obtain high shale oil yield and quality than CaCO₃.

不同催化剂对大城子油页岩重整油品的催化升级研究

在小型反应器中对大城子油页岩样品进行了Fe2O3和CaCO3的催化重整，评价了其对油页岩收率和品质的影响。结果表明：两种催化剂均增强了热解产物的干酪根反应活性和二次反应，对页岩油收率略有提高，但对热解挥发物含量有显著提高；催化剂的加入促进了杂原子化合物的裂化反应，提高了芳烃的选择性，促进了烯烃的芳构化。Fe2O3生成的页岩油具有较低的1-烯烃、芳烃、N和S含量，催化干酪根分解作用更明显，改善了重质组分和沥青质。衍生页岩油中总正烷烃含量约为总1-烯烃含量的2倍，主要含双环和三环芳烃。催化剂的使用提高了总正烷烃含量和环数较高的环链烷烃。在Fe2O3上更易发生萘的催化裂化。Fe2O3比CaCO3更有利于获得较高的页岩油收率和质量。图形抽象
