Title: Coal Technology Program progress report, March 1976

Abstract

Shakedown tests of the bench-scale hydrocarbonization system were successfully completed. Wyodak coal was fed to the reactor at a rate of 9.9 lb/hr where it was hydrocarbonized at 1050/sup 0/F under 20-atm hydrogen pressure. Laboratory results including settling tests, bench-scale settling tests, and sample ageing tests were continued. Two of ten compounds tested with the laboratory-scale apparatus were effective in increasing settling rates of solids in Solvent Refined Coal unfiltered oil, but bench-scale tests failed to show any improvements in the settling rate over the untreated SRC-UFO. Analytical chemistry efforts involved the removal and concentration of organic components in by-product waters from fossil fuel conversion processes. A sephadex gel is being used to achieve hydrophilic-lipophilic separations in organic mixtures as a step in the analysis of fossil fuel related materials. Engineering Evaluations of the Synthiol and Hydrocarbonization Processes continued with the Synthiol process flow diagrams, heat and material balances, and utilities requirements being completed. Inspection techniques were developed for wear- and process-resistant coatings. Orders were placed for the Incoloy 800 tubing and a smaller quantity of Inconel 600 tubing for the tube matrix in the coal-fueled MIUS fluidized bed. An engineering feasibility review of General Atomic's proposal to ERDA formore » a bench-scale test program on thermochemical water splitting for hydrogen production was completed. (auth)« less

  • ORNL's progress in coal research programs is reported: coal gasification and coal liquefaction (hydrocarbonization, residue carbonization, solids removal from coal liquids, pyrolysis, in-situ gasification synthoil process, analytical chemistry (of by-products, effluents, etc.), environmental effects (including study of carcinogens, mutagens, etc.), trace elements, materials technology, nondestructive testing, chemical research, and possible applications of process heat reactors.

    Progress is reported on a program designed to screen materials for use in gasification plants with respect to the various unique corrosive environments obtaining therein and to provide useful corrosion data as well as reliable information on other properties needed for the design, construction, and operation of such plants. The program is being pursued in five phases: Laboratory corrosion studies in gasifier environments at temperatures in the range of 900 to 2000/sup 0/F and a pressure of 1000 psi for exposure times up to 5000 hours; exposure of both alloys and refractories in selected locations of the Hygas, Consol, Synthane,more » Bigas and other pilot plants; a laboratory program of testing for times up to 400 hr. at temperatures up to 462/sup 0/F and pressures up to 1210 psi in aqueous gas-quench solutions typical of various pilot plants; a laboratory erosion-corrosion test program using char, ash, or dolomite as the erodent; and a testing program to determine the engineering properties of materials in the hostile environment obtaining in gasification plants.« less

  • The program comprises studies related to the technology of materials fabricated into thick-section primary-coolant containment systems of light-water-cooled nuclear power reactors. The principal area of investigation is the behavior and structural integrity of steel pressure vessels containing cracklike flaws. Current work is organized into the following tasks: fracture mechanics analyses and investigations, effect of high-temperature primary reactor water on the subcritical crack growth of reactor vessel steel, investigations of irradiated materials, pressure vessel investigations, and thermal shock investigations, and weld-heat-affected-zone cracking. Progress on work under the four existing research and development subcontracts is included in this report. (DLC)

    Activities carried out this quarter are described. These activities consisted of (1) a series of current distribution tests with a special electrode configuration, (2) slag/layer analysis of uncoated and cermet-coated electrodes, (3) a series of generator performance tests utilizing multiple loads and (4) a series of diffuser performance tests. In addition, installation of the new test leg, designated Configuration III, was completed and placed into operation.

  • During the study phase (Phase I) four concepts of the Coal Feeder were identified for further consideration and recommended for experimental evaluation under Phase II. These systems are: (1) the Ejector, using ejector pumps; (2) the Kinetic Extruder, using centrifugal forces to compact and extrude the pulverized coal; (3) the Ball Conveyor using gravity forces to feed the coal, and (4) the Fluid Dynamic task using bladeless disk type compressors. During the quarter covered by this report effort was concentrated on the refinement of the analytical tools and the design of test equipment and the test loop.
