MoS
2
常用作有机质催化加氢热解的高效催化剂,通过活化流动相的高压H
2
来提高热解产物的产率。但是MoS
2
催化剂是否对有机质自身热演化生烃有影响却少有研究。为此,通过对低成熟Alum页岩干酪根及添加MoS
2
催化剂的干酪根进行热模拟生烃对比实验,探究了MoS
2
对干酪根热演化生烃的影响。实验结果表明MoS
2
的加入使低熟干酪根具有更高的成烃潜力:①使轻烃(C
6-14
)峰值产率增加且峰值温度前移24 ℃,但重烃(C
14+
)峰值产率显著降低,表明MoS
2
加速了重烃向轻烃的热裂解转化;②使湿气产率在峰值温度(456 ℃)前轻微增加,但峰值温度后明显降低,表明MoS
2
促进了湿气的生成及后期的裂解;③使甲烷(C
1
)产率明显增加,特别是在528 ℃后C
1
增加了近50 %,这可能是因为MoS
2
促进了高-过成熟阶段干酪根的加氢作用;④通过FeS
2
(黄铁矿)与MoS
2
催化效应的系统对比,认为两种催化效应的差异主要受催化剂的结构、稳定性及硫的活性控制。
MoS
2
has been commonly used as an efficient catalyst for the kerogen hydropyrolysis to improve the yield with activated high-pressure and mobile phase of H
2
. However, there is little document on whether MoS
2
has a certain effect on the thermal maturation of organic matter and hydrocarbon generation. In this study, the effects of MoS
2
on the thermal evolution of organic matter and hydrocarbon generation are investigated by comparative thermal simulation experiments on kerogen of low maturity from the Alum Shale with and without MoS
2
added. The results show that low-mature kerogen has greater potential for hydrocarbon generation in presence of MoS
2
. MoS
2
acts to increase the peak yield of light hydrocarbons (C
6-14
), while decrease the peak yield of heavy hydrocarbons (C
14+
), and lowering the temperature of peak hydrocarbon generation by about 24 ℃ at the same time, indicating that MoS
2
serves to accelerate the thermal cracking of heavy hydrocarbons to light hydrocarbons. The adding of MoS
2
also can slightly increase the yield of wet gases (C
2-5
) before the peak hydrocarbon generation temperature (456 ℃) is reached, but significantly decrease it after the temperature surpasses its peak hydrocarbon generation value, indicating that MoS
2
can promote the generation and later cracking of wet gases. In addition, the existence of MoS
2
also remarkably raise the yield of methane (C
1
), especially at a temperature higher than 528 ℃ when the methane yield increases by nearly 50 %, a possible result of MoS
2
promoting the hydrogenation of kerogen at the high-to-over-mature stage. The difference of catalytic effect between pyrite (FeS
2
) and MoS
2
is systematically compared, which is mainly controlled by the structure, stability and sulfur activity of catalysts.
