Shale oil value enhancement research - Quarterly report: October 1 - December 31, 1993

A major push was made to identify the hydrocarbon and heteroatom types present in raw shale oil. A comprehensive, qualitative picture of the <400°C material has been obtained. In addition to the expected types, e.g., pyridines, pyrroles, indoles and phenols, the presence of aliphatic carboxylic acids, ketones and nitriles was confirmed. Most importantly, heteroatom types are able to be concentrated nearly quantitatively by liquid-liquid extraction with polar solvents. Compound types characterization of the >400°C material, as well as rapid, routine analysis of separations fractions, requires new methodologies founded in the Z-BASIC concept. Advances were made in establishing the interface protocol needed to utilize Z-BASIC methodologies for interpretation of gc-ms output data. It is anticipated that all interface protocols will be completed and a computerized reporting system will be in place by the end of the next quarter. Progress reports were made at the Contractor's Review Meeting (METC), November 16th and at the Eastern Oil Shale Symposium (Lexington), November 17th. Research results continue to be well-received. The concept of a thermodynamically logical map of potential products from shale oil is a sound approach to value-enhancement research. From a commercial perspective, the concept of establishing a demand for raw shale oil at a reasonable purchase price of, say $30/bbl, is increasingly being recognized as the best means of pulling shale oil into the marketplace. In the next quarter, a framework will be established for a conceptual commercial process. The main consideration in establishing a framework is the interrelationship between specialty/commodity chemicals and conventional petroleum refining products. Another consideration is the anticipated depth of processing and the level of refinment of the product slate. As part of the conceptual commercial process development, a preliminary process scheme for the pilot plant development (Phase-II) will be developed. Overall, the project is on schedule and on budget.
