SALT (System Analysis Language Translater): A steady state and dynamic systems code

Description: SALT (System Analysis Language Translater) is a lumped parameter approach to system analysis which is totally modular. The modules are all precompiled and only the main program, which is generated by SALT, needs to be compiled for each unique system configuration. This is a departure from other lumped parameter codes where all models are written by MACROS and then compiled for each unique configuration, usually after all of the models are lumped together and sorted to eliminate undetermined var… more

Project for laboratory study for removal of organic sulfur from coal

Description: Major accomplishments are listed: 1. It was found that molten sodium hydroxide (in place of mixed sodium and potassium hydroxides) followed by dilute sulfuric acid wash gave Gravimelt coal with the usual amount of sulfur and mineral matter removal but there was no MAF heat content loss over the small amount required for replacement of sulfur atoms by oxygen atoms in the coal structure - e.g., these samples had both measured heat content and MAF heat content in excess of 1400 Btu/lb. Therefore, … more

Development of new catalysts for coal liquids refining. Fourth quarterly report, October 1-December 31, 1979

Description: Base-line catalyst testing conditions for hydrotreating SRC-II fuel Oil Blend have been determined: temperature, 750/sup 0/F; pressure, 1000 psig; LHSV, 1 ml/ml-hr; and H/sub 2/ flow rate, 5000 SCF/bbl. At these conditions the average values for HDN and HDS after 24 hours on stream are approx. = 85% and 90% respectively with the best series of Ni-Mo on ..gamma..-alumina. Nickel and cobalt tungstate are significantly poorer catalysts. They afford 60-40% HDN and 85-75% HDS respectively. Nickel mo… more

[Surface studies of absorbents for the removal of SO[sub x] and NO[sub x]]

Description: During this quarter, we studied the x-ray absorption spectra of CaO and CaSO[sub 4] at high temperatures and used standard models to determine the calcium environment during coal combustion. The theoretical effort during this quarter was directed toward modeling the electronic structure of CuO supported on alumina; this is necessary for understanding the chemisorption processes for surface oxide and nitrogen oxide components of flue gas. 8 figs.

Combined Treatment of SO/sub 2/ and High Resistivity Fly Ash Using a Pulse Energized Electron Reactor

Description: The combined removal of SO/sub 2/ and high resistivity fly ash has been demonstrated in a pulse energized electron reactor (PEER). The PEER system which was originally developed for the removal of SO/sub 2/ utilizes a positive pulse streamer corona discharge in a non-uniform field geometry. In performance tests on SO/sub 2/, more than 90% was removed with an advantageously small power requirement. Combined treatment performance was demonstrated by introducing high resistivity fly ash into the t… more
