Abstract

Oil shale is a promising unconventional energy source whose processed oil products exhibit a H/C ratio comparable to that of crude oil. This study introduced a purely organic acid-base bifunctional porous material, HCP-BBA-S, and conducted a comprehensive investigation of its catalytic performance in the hydrothermal pyrolysis of oil shale under near-critical water conditions. Upon incorporation of the HCP-BBA-S catalyst, shale oil yield increased by 4.61–19.22 %, accompanied by a shift in oil composition towards lower carbon numbers and lower boiling points. Oxygen content in the products decreased significantly, improving oil quality and calorific value. Under optimized conditions, shale oil yield reached 41.85 %, with an H/C atomic ratio of 1.8 and a calorific value of 41.42 MJ/kg. These results highlight HCP-BBA-S as a highly effective catalyst for enhancing both the yield and quality of shale oil, offering a sustainable approach to unconventional energy resource utilization.

酸碱双功能多孔有机聚合物作为油页岩提质的高效催化剂

油页岩是一种很有前途的非常规能源，其加工成品油的H/C比值与原油相当。本研究引入了纯有机酸-碱双功能多孔材料HCP-BBA-S，对其在近临界水条件下对油页岩热液热解的催化性能进行了全面研究。在加入HCP-BBA-S催化剂后，页岩油收率提高了4.61-19.22 %，同时油的组成向低碳数和低沸点转变。产品中的氧含量显著降低，提高了油的品质和热值。在优化条件下，页岩油收率达到41.85 %，H/C原子比为1.8，热值为41.42 MJ/kg。这些结果表明，HCP-BBA-S是一种高效的催化剂，可以提高页岩油的产量和质量，为非常规能源的可持续利用提供了一种途径。
