| 摘 要： | 在对有机质进行加水高温高压热解实验时,经常会发现气体产物中的氢气含量非常高。通过大量的实验我们发现除了通常人们所认为的有机来源之外,还有很大一部分为无机成因,即不锈钢高压釜在高温高压条件下与水反应释放的氢气。在我们的实验中,无论是含有机质的还是仅含无机物的,产物中均有较大比例的氢气,其中在只有去离子水的模拟实验中也产生了一定量的氢气。这就证明不锈钢的高压釜确实参与了反应。这一因素必然会对模拟实验结果解释地质问题的有效性产生很大的影响.

| Abstract: | Hydrous pyrolysis using hig h-pressure autoclave, nowadays, is a relatively effective way to study petroleum geochemistry,which can simulate the process of oil and gas formation.In general, high percentage hydrogen is often found in the gas pyrolysate produced from organic in hydrous simulation experiments, which employ high-pressure autoclave.Most people beliveve the hydrogen mainly comes from organic reactions.In order to prove this problem, the authors have done a series of simulation experiments.In the experiment, the material of high-pressure autoclave is an alloy made from 1Cr18Ni9Ti and OCr17Ni12Mo2.The temperature of the experiments are under 330 ℃ and 330 ℃ for 72 hours.The quantity of water is accurately calculated.The experiment items include organic and inorganic matters, such as Fushun oil shale,Kaolinite and the deionized water, etc.The results several experiments show that the sources of hydrogen are not only organic reactions but also inorganic reactons.Particularly.the reactions in which only the deionized water is added into the high-pressure autoclave, also release hydrogen. This result proves the reaction between the high-pressure autoclaves and the deionized water at high thermal stress effectively.So the series of simulation experiment using high-pressure autoclave should be thought over and be modified, or the validity of the analysis and explanation of such experiments will be not reliable. |
