Shale ash (SA) as the carrier, the ratio of Cu to Ni in the Cu-Ni transition metal salt being, respectively, 1 : 0, 2 : 1, 1 : 1, 1 : 2, 0 : 1, the double transition metal salt catalyst (CumNin/SA) was prepared to explore the effect of such catalysts on the pyrolysis behavior and characteristics of Fushun OS. The research results show that the temperature (Tmax) corresponding to the maximum weight loss rate decreased by 12.9°C, 4.0°C, and 3.6°C; and the apparent activation energy decreased by 35.2%, 33.9%, and 29.6%, respectively, after adding catalysts Cu0Ni1/SA in pyrolysis. The addition of Cu0Ni1/SA and Cu2Ni1/SA further improves the shale oil (SO) yield of 3.5% and 3.1%, respectively. Cu0Ni1/SA produces more aromatic hydrocarbons, which, however, weakens the stability of SO and is of toxicity in use. After analyzing the pyrolysis product—semicoke (SC) and SO—with ATR-FTIR and GC-MS methods, CumNin/SA promotes the secondary cracking and aromatization of OS pyrolysis, increasing the content of the compound of olefins and aromatics in SO, and hastening the decomposition of long-chain aliphatic hydrocarbons to short-chain aliphatic hydrocarbons.

双过渡金属盐催化剂对抚顺油页岩热解的影响

以页岩灰（SA）为载体，Cu-Ni过渡金属盐中Cu与Ni的比例分别为1：0、2：1、1：1、1：2、0：1，双过渡制备了金属盐催化剂（CumNin/SA）以探讨该催化剂对抚顺OS热解行为和特性的影响。研究结果表明，最大失重率对应的温度（Tmax）分别降低了12.9°C、4.0°C和3.6°C；在热解中加入催化剂Cu0Ni1/SA后，表观活化能分别降低了35.2%、33.9%和29.6%。Cu0Ni1/SA和Cu2Ni1/SA的加入进一步提高了页岩油(SO)产率分别为3.5%和3.1%。Cu0Ni1/SA产生较多的芳烃，但会削弱SO的稳定性，使用时有毒性。
