✦ Synopsis

Progress in a continuing programme to develop kerogen elemental conversion relationships for 10 oil shale deposits is reported. Samples from one American and two Australian deposits were pyrolysed by Materlal Balance Modified Fischer Assay. Organic elements were determined from analyses of concentrated organic matter and direct analyses of the assay feed, products and residues. The oil shale samples examined were selected to cover Type I, II and III kerogens. Organic carbon conversions to oil ranged from 13 to 63%. Simplified pyrolysis stoichiometry (C, H, N, S, 0) was developed for each sample based on organic carbon accountabilities averaging 97.6 %.
