Abstract
A method for the quantitative determination of oil and gas formation in pyrolysis-gas chromatography. A diamondoid compound, such as adamantane, is used as an internal standard in pyrolysis-gas chromatography to quantitate oil and gas yields from kerogens on pyrolysis. Diamondold compounds are thermally stable and chemically unreactive with pyrolysis reaction products during oil and gas formation.
Claims8
A method for the quantitative determination of oil and gas formation in pyrolysis-gas chromatography comprising:
- pyrolyzing a weighed sample of carbon and hydrogen containing material capable of generating oil and gas admixed with diamondoid compound under an oxygen deficient atmosphere at a temperature of at least about 250.degree. C. to produce pyrolysis gas;
- analyzing the pyrolysis gas by gas chromatography;
- and
- quantitating with reference to diamondoid compound standard peak area integration.
