- W1557664749 abstract "The analysis of the organic fraction in shale leads to important processing insights. However, the analysis is complicated by the presence of a substantial fraction of rock. The rock often contains carbon, as carbonates, and hydrogen, as water of hydration, which make it extremely difficult to obtain a true organic analysis. The route used most often to obtain organic analyses is to isolate the kerogen by acid removal of the inorganics. This poses numerous problems in that the acids used, HCl and HF, can interact with and be incorporated into the organic matrix. Also basic nitrogen compounds are easily extracted from the shale. It has been observed that up to 20% of the organic carbon and up to 50% of the total nitrogen may be removed by acid extraction. To obviate these difficulties a procedure has been developed which utilizes the analyses of raw sink float shale samples to calculate the ratios of organic hydrogen and nitrogen to organic carbon. In addition an estimate of the hydrogen and nitrogen content of the mineral matter is obtained. (JMT)" @default.
