KEROGEN OIL VALUE ENHANCEMENT RESEARCH

Three general categories of products from the Estonia Kukersite kerogen oil were defined: pure compounds, broad range concentrates, and sweet refinery feedstock. Product development and market research center on these three categories. Further attempts were made to identify and test chemical approaches for producing lower alkyl resorcinols (what the market requires) from higher alkyl resorcinols. The approaches and process conditions tested have not yet produced satisfactory results. Progress w… more

West Hackberry tertiary project. Annual report, September 3, 1994--September 2, 1995

The West Hackberry Tertiary Project is a field test of the idea that air injection can be combined with the Double Displacement Process to produce a low cost tertiary recovery process which is economic at current oil prices. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering tertiary oil by gravity drainage. The Double Displacement Process is based upon the concept that in fields such as West Hackberry waterdrive recoveries are ty… more

Research program on fractured petroleum reservoirs. Quarterly report, January 1, 1995--March 31, 1995

In a number of experiments, the efficiency of solution-gas drive for both a light and a heavy oil was studied. These experiments reveal that solution-gas drive for a heavy oil of 11 API gravity is more efficient than a light oil of 35 API gravity.

The development of an integrated multistaged fluid-bed retorting process. Final report, September 1990--August 1994

This summarizes the development of the KENTORT II retorting process, which includes integral fluidized bed zones for pyrolysis, gasification, and combustion of oil shale. Purpose was to design and test the process at the 50-lb/hr scale. The program included bench- scale studies of coking and cracking reactions of shale oil vapors over processed shale particles to address issues of scaleup associated with solid-recycle retorting. The bench-scale studies showed that higher amounts of carbon cover… more

Ion exchange and adsorption on low rank coals for liquefaction

The objectives of this program are to study the application of catalysts and the catalysis of liquefaction of low rank coals. Ion exchange and adsorption techniques are being used or modified to incorporate catalytically active metals (Fe, Co, Ni and Mo) in relatively small (100-2000 ppM) quantities into coal samples. Relative oil yields are being determined by PETC and Auburn University workers as collaborators to establish the effectiveness of the catalyst incorporation techniques. It is hope… more

High efficiency shale oil recovery. Second quarterly report, April 1, 1992--June 30, 1992

The overall project objective is to demonstrate the high efficiency of the Adams Counter-Current shale oil recovery process. The efficiency will first be demonstrated at bench-scale, in the current phase, after which the demonstration will be extended to the operation of a small pilot plant. Thus the immediate project objective is to obtain data on oil shale retorting operations in a small batch rotary kiln that will be representative of operations in the proposed continuous process pilot plant… more

Effects of minerals on the pyrolysis of Kern River 650 F{sup +} residuum

Kern River 650 F{sup +} residuum (Kern Co, CA) and mixtures of Kern River 650 F{sup +} residuum with solids were examined by micropyrolysis at nominal constant heating rates from 1 to 50 C/min from temperatures of 100 to 700 C to establish evolution behavior, pyrolysate yields, and kinetics of evolution. The profiles for all samples generally exhibited two regimes of evolution: (1) low temperature (due to distillation), and (2) high temperature (due to cracking and distillation). The pyrolysate… more

Chemical reaction model for oil and gas generation from type 1 and type 2 kerogen

A global model for the generation of oil and gas from petroleum source rocks is presented. The model consists of 13 chemical species and 10 reactions, including an alternate-pathway mechanism for kerogen pyrolysis. Reaction rate parameters and stoichiometry coefficients determined from a variety of pyrolysis data are given for both type I and type II kerogen. Use of the chemical reaction model is illustrated for typical geologic conditions.

Relationship between hydrous and ordinary pyrolysis

Pyrolysis results are reviewed briefly with the intent of drawing comparisons between open, high pressure, and hydrous pyrolysis. Empirically, the degree of pyrolysis severity to form volatile products in open pyrolysis is similar to that required to form an expelled oil phase in hydrous pyrolysis. The yields of hydrocarbons from open pyrolysis are close to those from hydrous pyrolysis, but hydrous pyrolysis tends to assist the separation of hydrocarbons from polar materials. Pressure has a sma… more

Cooperative research in coal liquefaction. Final report, May 1, 1992--April 30, 1993

Research on sulfate and metal (Mo, Sn) promoted Fe{sub 2}O{sub 3} catalysts in the current year focused on optimization of conditions. Parameters varied included temperature, solvent, solvent-to-coal ratio, and the effect of presulfiding versus in situ sulfiding. Oil yields were found to increase approximately proportionately with both temperature and solvent-to-coal ratio. The donor solvent, tetralin, proved to give better total conversion and oil yields than either 1-methylnaphthalene or Wils… more

Extraction of lipid components from hibiscus seeds by supercritical carbon dioxide and ethanol mixtures

The genus Hibiscus exhibits great diversity in the production of natural materials with edible and industrial applications. The seeds of twelve varieties of Hibiscus were investigated as a source for triglycerides and phospholipids that could be used in functional foods. Lipid components were extracted from seed samples ground to a nominal particle diameter of 0.1 mm. Extractions were performed with an ISCO model 3560 supercritical fluid extractor using carbon dioxide and a mixture of carbon di… more

WETTABILITY ALTERATION OF CARBONATE ROCK MEDIATED BY BIOSURFACTANT PRODUCED FROM HIGH-STARCH AGRICULTURAL EFFLUENTS

Surfactants can be used to alter wettability of reservoir rock, increasing spontaneous imbibition and thus improving oil yields. Commercial synthetic surfactants are often prohibitively expensive and so a crude preparation of the anionic biosurfactant, surfactin, from Bacillus subtilis grown on high-starch industrial and agricultural effluents has been proposed as an economical alternative. To assess the effectiveness of the surfactin, it is compared to commercially available surfactants. In se… more

Investigation of the use of a recycle stream to mediate hydrogen transfer to improve the conversion of eastern oil shale to liquid products

The processing of eastern oil shale has long been known to require the addition of hydrogen to increase the oil yield. Several researchers, have investigated the use of both high pressure hydrogen and hydrogen donor solvents. Much of the donor solvent work has used pure,compounds such as tetralin and has not addressed the use of-a more realistic solvent such as one derived from the production process itself. The work reported herein is for the research Task 1.2.2, Process Studies, in the Annual… more

Advanced direct coal liquefaction concepts. Quarterly report, January 1, 1993--March 31, 1993

Five barrels of a Wilsonville process derived solvent (V-1074) from Black Thunder coal were obtained. This material boils within the preferred gas oil range, is more aromatic than previous solvents, and will therefore be used for the bench unit studies. Several repeat runs were performed in the autoclave to confirm the results of the matrix study. In addition, runs were carried out with different catalysts, with agglomerates and with the V-1074 solvent. The results of the autoclave runs were an… more

High efficiency shale oil recovery. Final report, January 1, 1992--June 30, 1993

The Adams Counter-current shale oil recovery process is an improved retorting technology enabling highly efficient oil recovery from oil shale. The high efficiency results primarily from the following facts: it (1) recovers the ash heat to preheat the feed ore; (2) burns and uses the coke energy and (3) operates without using hot ash recycling as a heat carrier. This latter feature is doubly important, contributing to high oil yield and to the generation of highly reactive coke which can be bur… more
