Book excerpt: The objective of this project is to develop a model for solid-liquid equilibria and a model for viscosities of the products of coal liquefaction processes. The same characterization procedure and representation by continuous distributions as used in previous work on vapor-liquid equilibria and excess enthalpies of coal liquids will be used. Models when fully developed will give the solid-liquid phase equilibrium properties and viscosities as factors of temperature and pressure for known molecular weight distribution and structural characterization of the coal liquid. To accomplish this well, the project requires three tasks: (1) Solid-Liquid phase equilibrium model development; (2) Experimental Viscosity Measurements; and (3) Viscosity Model Development. The work on development of a predictive model for saturated liquid volumes of coal model compounds has been completed. A manuscript has been prepared for submission to AIChE Journal. A copy of the manuscript is attached. Work on extending the viscosity model to coal derived liquids is continuing and progress on this work will be included in the next report.

This book was released on 1995 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The OSP (Operating Safety Procedure) required for performance of electrical arc testing of CFC replacement fluids was renewed. Electrical breakdown tests at one atmosphere pressure have been performed for R-22, R-134a, and R-125/R-143a (50:50 blend; R-507), and breakdown products identified. No differences in HCFC breakdown products are seen in the presence or absence of lubricant oils. The design of the high pressure-high temperature test stand has been finalized, and construction initiated during this quarter. Three motor stators and rotors were received from Tecumseh Products Company for use in motor burnout tests. A test plan for the motor breakdown tests is in preparation.

This book was released on 1996 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world continues to deplete its petroleum reserves, lower quality fossil fuels will play an increasingly important role in energy production. Heavy crude oil, coal liquids, and other heavy fossil fuels may be required to meet world energy needs. Heavy fossil fuels are generally higher in molecular weight, more aromatic, and contain more heteroatoms than higher quality petroleum. There will be an increasing need to deal with such low quality feedstocks, and therefore, an incentive to learn more about their properties. There is also significant current interest in the general area of coal pyrolysis, particularly with respect to comprehensive models of this complicated phenomenon. This interest derives from the central role of pyrolysis in all thermally driven coal conversion processes - gasification, combustion, liquefaction, mild gasification, or thermal beneficiation. There remain several key data needs in these application areas. Among them is a need for more reliable correlations for predicting vapor pressures of heavy, primary coal tars. Such information is important in design of all coal conversion processes, in which the volatility of tarry products is of major concern. This work presents results on vapor pressures and vaporization heat of polycyclic aromatic hydrocarbons and mixtures found in coal tar.

Book excerpt: Specific surface area, as well as its accessibility to gaseous reactants, are of paramount importance for all heterogeneous interactions occurring at coal char surfaces. Accessibility of this surface area is governed by the pore structure morphology of the char; i.e., pore size distribution, tortuosity, intersections, shape, etc. The porosity morphology of coal chars varies over a considerable range and is determined by a large number of factors including the nature of the porosity of the precursor material prior to carbonization, the carbonization process, and extent and method of any subsequent activation or gasification. A persistent problem in this area has been the reliable, quantitative measurement and characterization of the resultant porosity, especially the micropores. The following was accomplished during the reporting period: use of the random pore model as a method of rationalizing the data obtained from CO and CO2 TPD spectra has been initiated; and [alpha]-plot data obtained for Wyodak coal char samples prepared at various degrees of burn-off, ranging from 0--75% burn-off, in 0.1 MPa oxygen at 470 C, were used to compare with random pore model predictions. Conclusions derived from this analysis include: the random pore model predictions are consistent with the evolution of sample surface area and porosity with burn-off as determined for the Wyodak coal char samples; and the parameters obtained from the random pore model provide a reasonably good comparison with the [alpha]-plot data.
