Solvent Treatment Of Coal For Improved Liquefaction

US Patent:
H69, Jun 3, 1986
Filed:
Nov 6, 1985
Appl. No.:
6/795302
Inventors:
Herbert R. Appell - Pitcairn PA
Nand K. Narain - Bethel Park PA
Bruce R. Utz - Pittsburgh PA
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:
C10G 100
C10B 4902
C10B 5304
US Classification:
208 8LE
Abstract:
Increased liquefaction yield is obtained by pretreating a slurry of solid carbonaceous material and a liquid hydrocarbonaceous solvent at a temperature above 200. degree. C. but below 350. degree. C. for a period of 10 minutes to four hours prior to exposure to liquefaction temperatures.

Pressure Gradient Passivation Of Carbonaceous Material Normally Susceptible To Spontaneous Combustion

US Patent:
6146432, Nov 14, 2000
Filed:
Jul 15, 1999
Appl. No.:
9/354051
Inventors:
Thomas L. Ochs - Albany OR
William D. Sands - Butler PA
Karl Schroeder - Pittsburgh PA
Cathy A. Summers - Albany OR
Bruce R. Utz - Pittsburgh PA
Assignee:
The United States of America as represented by the Department of Energy - Washington DC
International Classification:
C10L 500
US Classification:
44501
Abstract:
This invention is a process for the passivation or deactivation with resp to oxygen of a carbonaceous material by the exposure of the carbonaceous material to an oxygenated gas in which the oxygenated gas pressure is increased from a first pressure to a second pressure and then the pressure is changed to a third pressure. Preferably a cyclic process which comprises exposing the carbonaceous material to the gas at low pressure and increasing the pressure to a second higher pressure and then returning the pressure to a lower pressure is used. The cycle is repeated at least twice wherein the higher pressure may be increased after a selected number of cycles.

Method For Dispersing Catalyst Onto Particulate Material

US Patent:
5096570, Mar 17, 1992
Filed:
Jun 1, 1990
Appl. No.:
7/531722
Inventors:
Bruce R. Utz - Pittsburgh PA
Anthony V. Cugini - Pittsburgh PA
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:
C10G 100
US Classification:
208423
Abstract:
A method for dispersing finely divided catalyst precursors onto the surface of coal or other particulate material includes the steps of forming a wet paste mixture of the particulate material and a liquid solution containing a dissolved transition metal salt, for instance a solution of ferric nitrate. The wet paste mixture is in a state of incipient wetness with all of this solution adsorbed onto the surfaces of the particulate material without the presence of free moisture. On adding a precipitating agent such as ammonia, a catalyst precursor such as hydrated iron oxide is deposited on the surfaces of the coal. The catalyst is activated by converting it to the sulfide form for the hydrogenation or direct liquefaction of the coal.
