Pelletizing/reslurrying as a means of distributing and firing clean coal

Description: The objective of this study is to develop technology that permits the practical and economic preparation, storage, handling, and transportation of coal pellets, which can be reslurried into Coal water fuels (CWF) suitable for firing in small- and medium-size commercial and industrial boilers, furnaces, and engines. The project includes preparing coal pellets and capsules from wet filter cake that can be economically stored, handled, transported, and reslurried into a CWF that can be suitably at… more

Pelletizing/reslurrying as a means of distributing and firing clean coal. Final quarterly technical progress report No. 7, January 1, 1992-- March 31, 1992

Description: Work in this quarter focused on completing (1) the final batch of pilot-scale disk pellets, (2) storage, handling, and transportation evaluation, (3) pellet reslurrying and atomization studies, and (4) cost estimation for pellet and slurry production. Disk pelletization of Elkhorn coal was completed this quarter. Pellets were approximately 1/2- to 3/4-in. in diameter. Pellets, after thermal curing were strong and durable and exceeded the pellet acceptance criteria. Storage and handling tests in… more

Pelletizing/reslurrying as a means of distributing and firing clean coal

Description: Battelle-Columbus and Amax Research Development conducted a program to develop a process to transport, handle, store, and utilize ultra-fine, ultra-clean (UFUC) coals. The primary objective was to devise a cost-effective method, based on conventional pelletization techniques, to transform the sludge-like filter cake produced in advanced flotation cleaning processes into a product which could be used like lump coal. A secondary objective was the production of a pellet which could be readily conv… more

Novel approach to coal gasification using chemically incorporated catalysts (Phase II). Final report, May 1978-June 1981

Description: Since 1974, Battelle has been developing a catalytic treatment process that would allow more economic, efficient and reliable utilization of the vast deposits of eastern coals in gasification systems. In order to keep the process simple and economic, a disposable catalyst lime (CaO), was employed. It was found that the effectiveness of low concentrations of CaO was greatly increased by thorough incorporation into the coal. As a result of these efforts, a catalytic treatment system has been deve… more

Development of the Nested Fiber Filter

Description: Battelle, has tested the Nested Fiber Filter (NFF) as a particulate control device for high temperature, high-pressure (HTHP) applications. Battelle funded initial bench-scale tests which were the basis for patents and a concept applying the NFF. Subsequent parametric tests in a 6-inch diameter reactor established excellent particulate capture performance, > 99 percent, for conditions up to 1600 F and 6 atmospheres. Effective cleaning/regeneration of the NFF was achieved in the 6-inch scale wit… more

Advanced Development of the Nested Fiber Filter: Phase 1, Evaluation of cleaning Methods

Description: Battelle has completed Phase I of the DOE program to evaluate cleaning methods for the Nested Fiber Filter (NFF). The results of the investigations into fly ash bonding mechanisms, and mechanical vibration and acoustic vibration techniques led to the conclusion that acoustic cleaning with a pulse combustor is the preferred integrated system for high-temperature, high-pressure applications.

Molecular biological enhancement of coal biodesulfurization. First quarterly technical progress report

Description: The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: Clone and characterize the genes encoding the enzymes of the ``4S`` pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; return multiple copies of genes to the original host to enhance the biodesulfurization activity of that organism; transfer this pathway into a f… more
