The objective of this study was to investigate the feasibility of using the cementitious properties and agglomeration characteristics of coal conversion byproducts to encapsulate and immobilize hazardous waste materials. The intention was to establish an economical way of co-utilization and co-disposal of wastes. In addition, it may aid in the eradication of air pollution problems associated with the fine-powdery nature of fly ash. Encapsulation into agglomerates is a novel approach of treating toxic waste. Although encapsulation itself is not a new concept, existing methods employ high-cost resins that render them economically unfeasible. In this investigation, the toxic waste was contained in a concrete-like matrix whereby fly ash and other cementitious waste materials were utilized. The method incorporates the principles of solidification, stabilization and agglomeration. Another aspect of the study is the evaluation of the agglomeration as possible lightweight aggregates. Since fly ash is commercially used as an aggregate, it would be interesting to study the effect of incorporating toxic wastes in the strength development of the granules. In the investigation, the fly ash self-cementation process was applied to electroplating sludges as the toxic waste. The process hoped to provide a basis for delisting of the waste as hazardous and, thereby …

A bench-scale reactor is being used to conduct studies of the conversion of synthesis gas to methanol by a novel process. In previous reports, we provided evidence for a two step reaction in series: the carbonylation of methanol to methyl formate taking place in a non-equilibrium region in the vicinity of the copper chromite surface, and the hydrogenolysis of methyl formate to methanol taking place on the surface of the copper chromite. The synergism between the two catalysts enhances the rate of methanol formation. In this quarter, we tested several copper chromites (with different surface areas and stabilizing agents) on the rate of methanol synthesis. It seems likely that pore diffusion limitations control the hydrogenolysis reaction since the rate of methanol formation is proportional to the square root of the copper chromite surface area. Elemental analyses using Inductively Coupled Plasma analysis and pore size distribution analysis of copper chromite were carried out.

The objective of this research is to develop a mechanistic understanding of the oxidation of coal and coal pyrite, and to correlate the intrinsic physical and chemical properties of these minerals, along with changes resulting from oxidation, with those surface properties that influence the behavior in physical coal cleaning processes. The results will provide fundamental insight into oxidation, in terms of the bulk and surface chemistry, the microstructure, and the semiconductor properties of the pyrite. During the fifth quarter, wet chemical and dry oxidation tests were done on Upper Freeport coal from the Troutville {number_sign}2 Mine, Clearfield County, Pennsylvania.

Lawrence Livermore National Laboratory (LLNL) needs a 1.15:1 magnification relay lens that will image a CRT with fiber optics faceplate onto a CCD detector array. Optical Research Associates (ORA) designed a similar lens several years ago with a different magnification (2.5:1 see Reference 1). LLNL had the lens built, and it performed satisfactorily. Now a larger CCD is available, and LLNL needs this new design to have many features of the earlier form except for magnification. Some of these features include virtual telecentricity at both the input and output of the lens, high collection and transmission efficiency, low image distortion, and moderately high MTF modest spatial frequency in the image. A reference in this report lists the complete set of requirements and goals for an intermediate magnification, and we repeat many of them in this report. LLNL has changed the magnification requirement, because we found that the design could not meet some of the former mechanical constraints with the new goal. During the design process, we found that a lens based on previous form (double gauss derivative) was very sensitive to small errors of construction (such as element thickness and centering). We decided to try an alternate design that is …

This progress report describes the monitoring being done to validate a linkage of anthropogenic aerosol to clouds and climate. Equipment and findings are reported. The equipment construction called for in the original proposal has now been competed. These instruments are the high temperature processor, the data acquisition system for the direct Royco optical particle counter (OPC), and modifications to the formvar replicator. The main field effort during the past year has been the shipboard experiment SEAHUNT (Shiptrail Evolution Above High Updraft Naval Targets). There were also some laboratory and local ambient particle measurements and a surface field program on and near the California coast. The shipboard project was not anticipated in the original proposal but the laboratory and surface measurements were along the lines suggested in the original proposal.

The goal of the research performed here is to study and understand the nature of fine scale microchemical variation, on the order of the lattice periodicity, in ceramic oxides. To that end, during the past year, emphasis was placed on the selection of appropriate materials systems and their fabrication into samples suitable for study using advanced high resolution analytical electron microscopy (work to be performed in the coming year). The work concentrated on two materials systems.
