Book excerpt: During 1979-80, a new generation of very active, long-lived catlaysts for hydrotrating was discovered at the Stamford Research Laboratories of the American Cyanamid Company. The catalysts are based on a unique substrate prepared in bead form from a rehydratable alumina. Their spherical shape, crush strength, and abrasion resistance seem ideally suited for the ebullated bed reactors used in the H-COAL process developed by Hydrocarbon Research, Inc. (HRI). The beads have internal pore structures that are controllable over a wider range than conventional alumina supports, leading to active catalysts that are resistant to poisoning. In September, 1981, the Department of Energy granted a 3-year contract to the American Cyanamid Company for the development of significantly improved catalysts for coal liquefaction anf for upgrading coal extracts, particularly in reactors used in the H-COAL process. Catalysts will first be screened in a batch reactor to identify promising candidated. The latter will be tested in a continuous aging reactor to evaluate their resistance to deactivation under col-liquefaction and extract upgrading conditions. Cold flow ebullation tests of catalysts of different head size are presented, along with some screening and crying of experimental catalysts. Spherical methods for examining catalysts are described.

Quarterly Progress Report No. 7, April 1-June 30, 1983 written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of twenty-five experimental bead catalysts were tested for coal liquefaction activity in batch screening trials. Six factors relating to support preparation and composition, molybdenum, nickel, and cobalt levels, and additives, were varied according to a statistical design. Molybdenum (MoO3) and NiO/CoO promotor levels were found to correlate most closely with coal conversion and sulfur removal. Support composition and additive variables had detrimental effects only at particular levels. Batch testing with coal extracts was initiated. Runs were done to gain experience in processing extracts as well as to develop satisfactory work-up procedures. Results of baseline runs are given. Surface characterization of experimental bead catalysts continued. X-ray photoelectron and electron microprobe techniques were used. Results are compared to activity test data. 9 references, 6 figures, 12 tables.

Book excerpt: Cold flow ebullation tests to determine the ranges of operability of bead catalysts continued. Data reported show the effects of higher catalyst density, wider particle size distributions, and higher fluid viscosity on ebullation of bead catalysts. A relation for determining limiting diameters in a liquid-solid fluidized bed was developed. Correlation of the three-phase data is being investigated. The CSTR Catalyst Aging Test Unit is described. The system operates under computer control. High pressure hydrogen and coal slurry are fed continuously to a one-liter stirred autoclave. High pressure nitrogen for inerting and flush oil are used in the event of an interlock shutdown. The product is passed to a 3-gallon collection vessel or to a smaller sampling vessel during material balance periods. The gas disentrains from the mixture and is scrubbed. Analytical techniques to be used in the course of the catalyst testing program were evaluated. H-COAL PDU products and SRC-II Heavy distillate were analyzed. Standard deviations for many of the procedures were determined. Specific methods are summarized. Development of surface analytical techniques to study coal liquefaction catalysts focused on used Amocat 1A catalysts from coal run 10 at the H-COAL Pilot Plant. Preliminary results of analysis by ESCA and x-ray microprobe are given.

Book excerpt: Studies of the chemistry and catalysis of coal hydrogenation have been initiated with the construction of a flow reactor for extraction of coal and the development of analytical techniques. Work was initiated on the design of a rotor for /sup 13/C nuclear magnetic resonance of solid coal and extracted coal. Studies on momentum, heat and mass transfer in a fluidized bed simulated conditions for coal hydrogenation and were used to investigate effects of particle size and solids loading. The catalytic upgrading of coal-derived liquids is investigated by studies of the catalytic denitrogenation, desulfurization, deoxygenation and cracking of model compounds. Aging of Co-Mo catalysts was found to reduce the number of active sites but not the nature of the sites. A Raney catalyst is being developed for the hydrogenation of carbon monoxide. Temperature programmed desorption was used to study the properties of an iron manganese oxide catalyst previously shown to give high yields of C/sub 2/-C/sub 10/ hydrocarbons.
