| 摘 要： | 粘土矿物，碳酸盐，石英等无机矿物对有机质演化的催化作用已被确认，有机质干酪根类型还与黄铁矿含量，形态有关，而其中硫的含量直接影响到干酪根反应的活化能，反应速率，指出黄铁矿也是一种有效的催化剂。鉴于世界原油中有很大一部分产自高硫酪根，深入研究其中的机理是当前石油地球化学中的一项刻不容缓的任务。

| Abstract: | It is well known that some inorganic minerals such as clay minerals, carbonates, quartz are effective catalysts in the evolution of organic matter. This paper discusses the catalysis of pyrite in hydrocarbon generation. The kerogen types are related to the content, geometry of pyrite,The data showed that pyrite sulfur content of the kerogen is the function of its active energy and reaction rate. An assumption that pyrite is also a geologic catalyst of petroleum generation is presented. Since a great number of the world oil are derived from the sulfur-rich kerogens, the current task is to investigate the mechanism of pyrite catalysis in petroleum generation. |
