Process for clean-burning fuel from low-rank coal

Patent Merriam, Norman W [Laramie, WY]; Sethi, Vijay [Laramie, WY]; Brecher, Lee E [Laramie, WY]

A process for upgrading and stabilizing low-rank coal involving the sequential processing of the coal through three fluidized beds; first a dryer, then a pyrolyzer, and finally a cooler. The fluidizing gas for the cooler is the exit gas from the pyrolyzer with the addition of water for cooling. Overhead gas from pyrolyzing is likely burned to furnish the energy for the process. The product coal exits with a tar-like pitch sealant to enhance its safety during storage.

Method for removing volatile components from a ceramic article, and related processes

Patent Klug, Frederic Joseph [Schenectady, NY]; DeCarr, Sylvia Marie [Waterford, NY]

A method of removing substantially all of the volatile component in a green, volatile-containing ceramic article is disclosed. The method comprises freezing the ceramic article; and then subjecting the frozen article to a vacuum for a sufficient time to freeze-dry the article. Frequently, the article is heated while being freeze-dried. Use of this method efficiently reduces the propensity for any warpage of the article. The article is often formed from a ceramic slurry in a gel-casting process. A method for fabricating a ceramic core used in investment casting is also described.

In situ formation of coal gasification catalysts from low cost alkali metal salts

Patent Wood, Bernard J [Santa Clara, CA]; Brittain, Robert D [Cupertino, CA]; Sancier, Kenneth M [Menlo Park, CA]

A carbonaceous material, such as crushed coal, is admixed or impregnated with an inexpensive alkali metal compound, such as sodium chloride, and then pretreated with a stream containing steam at a temperature of 350.degree. to 650.degree. C. to enhance the catalytic activity of the mixture in a subsequent gasification of the mixture. The treatment may result in the transformation of the alkali metal compound into another, more catalytically active, form.

Process to improve boiler operation by supplemental firing with thermally beneficiated low rank coal

Patent Sheldon, Ray W [Huntley, MT]

The invention described is a process for improving the performance of a commercial coal or lignite fired boiler system by supplementing its normal coal supply with a controlled quantity of thermally beneficiated low rank coal, (TBLRC). This supplemental TBLRC can be delivered either to the solid fuel mill (pulverizer) or directly to the coal burner feed pipe. Specific benefits are supplied based on knowledge of equipment types that may be employed on a commercial scale to complete the process. The thermally beneficiated low rank coal can be delivered along with regular coal or intermittently with regular coal as the needsmore » require. « less

Low-rank coal oil agglomeration product and process

Patent Knudson, Curtis L [Grand Forks, ND]; Timpe, Ronald C [Grand Forks, ND]; Potas, Todd A [Plymouth, MN]; ...

A selectively-sized, raw, low-rank coal is processed to produce a low ash and relative water-free agglomerate with an enhanced heating value and a hardness sufficient to produce a non-decrepitating, shippable fuel. The low-rank coal is treated, under high shear conditions, in the first stage to cause ash reduction and subsequent surface modification which is necessary to facilitate agglomerate formation. In the second stage the treated low-rank coal is contacted with bridging and binding oils under low shear conditions to produce agglomerates of selected size. The bridging and binding oils may be coal or petroleum derived. The process incorporates a thermalmore » « less
