9820862Larsen Deep inside the earth, petroleum is formed from the decomposition of a macromolecular solid (kerogen) which is all that remains of the biological ultimate oil precursors. The kerogen is locked in the pores of rocks and is usually only a few per cent of the rock. The chemistry responsible for the conversion of kerogen to petroleum is not understood. There are indications that it may involve catalysis by some of the minerals present and may also involve reactions with the water present. We will determine whether some of the best mineral mater catalyst candidates can bring about petroleum forming reactions between kerogens and water. Positive results would not only aid in petroleum exploration and in understanding the carbon cycle, but might open new processing and upgrading possibilities for heavy oils.

在地球深处，石油是由一种大分子固体（干酪根）分解形成的，这是生物最终石油前体的全部残余。干酪根被锁在岩石的孔隙中，通常只占岩石的百分之几。干酪根转化为石油的化学原理尚不清楚。有迹象表明，它可能涉及到一些存在的矿物质的催化作用，也可能涉及到与存在的水的反应。我们将确定一些最佳的矿物催化剂候选物是否能在干酪根和水之间产生成油反应。积极的结果不仅有助于石油勘探和理解碳循环，而且可能为重油的加工和升级开辟新的可能性。
