Keyword:  天然矿物脂肪酸酯水解生烃影响因素;
Abstract: 在常压、低温条件下,检测了十种天然矿物存在下水的pH值变化、天然矿物经偏酸性和偏碱性水溶液浸泡后的物相组成;同时观察了十种天然矿物及其在不同(沉积环境)pH值时对脂肪酸酯的水解催化作用,得出脂肪酸酯在不同天然矿物存在下的水解率大小(由此可计算出生烃量).实验结果表明:十种天然矿物存在下可使偏酸性或偏碱性水的pH值发生变化,但天然矿物的物相组成在偏酸性或偏碱性水溶液浸泡后基本上不变;除了白云石和钙蒙脱石外,大多数天然矿物在偏碱性条件下对脂肪酸酯低温催化水解都是比较有利的;脂肪酸酯低温矿物催化水解的水解率范围在9%~50%,大多数集中在22%~34%范围.
