Available in PDF, EPUB and Kindle. Book excerpt: The focus of the phase-I research effort is now on exploratory level verification of the candidate process schemes. We are quite confident of the basic strategy, namely, division of the barrel by polarity and separate processing of the polar and non-polar streams. Processing of the non-polar stream must necessarily focus on the high value products found in the +400 °C fraction. We expect that waxes will meet high quality paraffin-wax specifications (partly because of the high initial boiling point) but the lube oil quality is not yet known. Verification of the polars processing scheme is aimed at determining the balance between broad-range concentrates and pure compounds. We have identified buyers for both types of streams but it is not yet clear how much value-addition is economically desirable. In the early stages of this work, we showed that there is an optimum level of processing and that over-processing might actually reduce the IRR. We are proceeding with the pilot plant developments in areas where we are confident of the process steps, eg. distillation and liquid-liquid extraction while completing the verification work before deciding what to do about piloting HDA, catalytic hydrotreating and liquid-solid adsorption.

Available in PDF, EPUB and Kindle. Book excerpt: Activities during this quarter focused on using the phase-I results to define process sequence alternatives for phase-II. Two process alternatives have been devised while obtaining the desired marketable product slate. The status of required process units has been evaluated. While there are some units that need to be designed and fabricated, the upstream process units are in place to proceed with the process plan. Separations have been completed and analyzed on three of the four shale oil fractions. The extraction work on the heaviest fraction has run into difficulties due to equipment design limitations. Modifications are in progress to rectify this problem and to complete the planned work. The separations and analytical work on the middle distillate fraction (275-400 C) have been completed. The solvent system has performed as expected and will be used in the pilot system in phase-II. The work on conversions task has steered in the direction of using thermal hydrodealkylation (THD) process to dealkylate polar fractions. The THD process is expected to yield low molecular weight polar compounds/concentrates that are suitable for market needs. The design and fabrication will be initiated in the next quarter. The analytical procedures and characterization task is in the final stages of refinement to complete the software as expected. The Z-BASIC software, eventually, will be used to monitor separations by tracking compound types or z-types. Present modifications are expected to provide z-type distributions. The decision-making routines need further refinement. The progress of the development work slowed a little during this quarter due to work load demand from other projects. However, serious efforts will be made to meet the original project schedule.

Available in PDF, EPUB and Kindle. Book excerpt: Activities during this quarter focused on integrating the various tasks and elements. During Phase-1, substantial effort was placed on designing and automating the identification of molecular types present in shale oil. The ability to know the molecular composition and to track a given ''target'' species through the initial concentration steps was deemed critically important to the ultimate success of the three-phase project. It has been this molecular tracking ability that clearly distinguishes the JWBA work from prior shale oil research. The major software and hardware tasks are not in place to rapidly perform these analytical efforts. Software improvements are expected as new questions arise. The existence of the major nitrogen and oxygen types in shale oil has been confirmed. Most importantly, the ability to convert higher molecular weight types to lower molecular weight types was preliminarily confirmed in the present quarter. This is significant because it confirms earlier hypothesis that values are found though out the boiling range. Potential yields of extremely high value chemicals, e.g., $1000/bbl of up to 10% by weight of the barrel remain a feasible objective. Market and economic assessment continue to show encouraging results. Markets for specialty and fine chemicals containing a nitrogen atom are expanding both in type and application. Initial discussions with pharmaceutical and agrochemical industries show a strong interest in nitrogen-based compounds. Major progress was made during this quarter in completing agreements with industry for testing of shale oil components for biological activity. Positive results of such testing will add to the previously known applications of shale oil components as pure compounds and concentrates. During this quarter, we will formulate the pilot plant strategy for Phase-11(a).

Available in PDF, EPUB and Kindle. Book excerpt: Activities during this quarter focused on compound type analysis of shale oil extraction products and improvement of the continuous extraction process. We have installed a walk-in fume hood to improve the ventilation of our working environment while handling of larger amounts of shale oil and volatile solvents in our Phase-II(a) work. The fume hood accommodates the distillation column, rotary evaporator, and the CLLX column. During the construction period, experimental work was carried on at a smaller scale. Modifications to the thermal hydrodealkylation process unit at the University of Utah have been completed. The higher boiling polar fraction of shale oil was fed and the preliminary ran showed promising results. The search for potential industrial partners is continuing. During this period, the prijcipal investigator has visited six industrial companies that are candidates for partner/buyer relationship. Currently, we are pursuing confidentiality agreements with four of them. It is the intent to focus our research toward addressing the objectives of those companies who show sufficient interest in the shale oil value enhancement project to enter the next level of discussions.

Available in PDF, EPUB and Kindle. Book excerpt: 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 nitrites was confirmed. Most importantly, heteroatom types are able to be concentrated nearly quantitatively by liquid-liquid extraction with polar solvents. Compound types characterization of the400°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.

Available in PDF, EPUB and Kindle. Book excerpt: All tasks are on schedule, or ahead of schedule. Particular progress has been made in identifying industrial entities, commodities and specialty products of target interest for shale oil-derived products. There is clearly a major emphasis worldwide on new chemicals and shale oil-derived structures are similar to many of these chemicals of interest. Details of the mathematical modeling, programming and algorithm development have progressed with excellent results. Considerable effort will be required to interface these with the output of the gc/ms but we are receiving excellent support from Hewlett Packard in this regard. The ability to concentrate particularly valuable compounds with reasonable projected cost processes continues to show promise. In one system, a single-stage extraction recovered 87% of the total nitrogen in an extract representing only 33% of the fraction. Special attention is being paid to both nitrogen types and oxygen types. The raffinates from the polar solvent extractions will be evaluated for their oil and wax contents. All of the start-up infrastructure is now in place. Subcontracts have been initiated and equipment and supplies have been procured. We are now planning a major push to reach some general findings by early in 1994. From these findings, we will be prepared to focus on experimental verification of process design needed for the second program phase.

Available in PDF, EPUB and Kindle. Book excerpt: A review of the marketing, compositional analysis, and process data has pointed to a simplification of the process scheme envisaged for the phase-H continuous process work. This translates into a higher probability of success, both for the R & D and the likelihood of securing an industrial partner for future commercialization. The phase-II PDU construction work is well-along and will be completed in the next quarter. The high efficiency distillation unit is complete and the liquid-liquid extraction unit is operable at ambient temperature and pressure conditions. Flow diagrams of preferred processes for recovery of refinery feeds, aromatics, waxes, and lube oils from oil shale are presented.

Available in PDF, EPUB and Kindle. Book excerpt: The overall objective is to develop a new technology for manufacturing valuable marketable products from shale oil. The quarter's efforts were concentrated on (a) THDA and reaction of alkylpyridines at elevated conditions, (b) compound type analysis of kerogen oil and its derived products, (b) thermal hydrodealkylation of the> 290°C polar fraction, (c) secondary reactions of pyridinic type compounds to form marketable products, and (d) preparation of presentation to the Dawnbreaker Commercial Assistance Program. Excellent progress is being made in all cases. Our market analysis and industrial feedback indicate that the low molecular weight pyridines are the main market driving force. We are concentrating our effort toward increasing the yield of ''light'' pyridines before the end of Phase II(a). Our current laboratory set-up can only produce analytical quantity of samples, which is not sufficient for marketing purpose. However, the completion of a secondary flow THDA unit for a pilot-scale production depends on the availability of the Phase-II(b) and Phase-III funding.
