Characterization of Devonian Shales Using Laser Pyrolysis-Gas Chromatography

摘要

Pulsed Nd pyrolysis with minimum sample pretreatment generates adequate quantities of products for analytical determinations. Significant quantities of pyrolysis products apparently result from methane and ethane released by thermal degradation. Focused power deposition leads to increased ethane production. This may result from a deeper penetration into the sample exploring regions removed from the surface that are less depleted in naturally occurring low molecular weight gases. Higher molecular weight components are readily apparent. These compounds may serve both as useful chemical markers and as component sections of the larger molecular weight species that contain the candidate gaseous fuels. (ERA citation 03:016785)
