Development of the chemical and electrochemical coal cleaning process

Description: Studies concerning the use of flotation as an alternative method of separating liberated mineral matter from chemical/electrochemical coal cleaning (CECC) treated coal were continued using Elkhorn No. 3 coal. The results obtained using different methods of recovering the clean product after CECC treatment showed trends similar to those observed previously with Pittsburgh No. 8 coal. The use of flotation after CECC treatment of the Elkhorn No. 3 coal was found to be more efficient than wet-scree… more

Co-combustion of refuse derived fuel and coal in a cyclone furnace at the Baltimore Gas and Electric Company, C. P. Crane Station

Description: A co-combustion demonstration burn of coal and fluff refuse-derived fuel (RDF) was conducted by Teledyne National and Baltimore Gas and Electric Company. This utility has two B and W cyclone furnaces capable of generating 400 MW. The facility is under a prohibition order to convert from No. 6 oil to coal; as a result, it was desirable to demonstrate that RDF, which has a low sulfur content, can be burned in combination with coals containing up to 2% sulfur, thus reducing overall sulfur emission… more

Economical clean carbon fuel and co-product gaseous and liquid from coal

Description: Unlike its predecessors, the HYDROCARB Process converts coal or other carbonaceous feedstock to a clean carbon fuel and co-product gaseous hydrogen- and/or methane (CH{sub 4})-rich gas and/or liquid methanol. Feedstock carbon content is essentially extracted as pure particulate carbon, free of sulfur, nitrogen, and ash. By eliminating the need to manufacture large quantities of hydrogen, lower capital cost and higher thermal efficiency result compared to previous coal-to-synthetic-fuel processe… more

A Novel Coal Feeder for Production of Low Sulfur Fuel

Description: A dual-screw feeder was designed and tested for desulfurization of coal. The key parts of this reactor are two screw tubes which independently feed coal and calcined lime, the inner tube acting as a coal pyrolizer and the outer tube acting as a desulfurizer with hot calcined lime pellets or other renewable sorbent pellets. The objective of this project is to study the feasibility of this advanced concept of desulfurization using the coal feeder. In this quarter, the following tasks have been pe… more

Hydrotreating the bitumen-derived hydrocarbon liquid produced in a fluidized-bed pyrolysis reactor

Description: The pyrolysis of bitumen-impregnated sandstone produces three primary product streams: C{sub 1}-C{sub 4} hydrocarbons gases, a C{sub 5}{sup +} total liquid product, and a carbonaceous residue on the spent sand. The bitumen-derived hydrocarbon liquid was significantly upgraded relative to the native bitumen: it had a higher API gravity, lower Conradson carbon residue, asphaltene content, pour point and viscosity and a reduced distillation endpoint relative to the native bitumen. The elemental co… more

Cloning and expression of the sulfoxide/sulfone/sulfonate/sulfate genes in Pseudomonads and Thiobacillae. [Pseudomonas, Thiobacillus, Rhodococcus]

Description: The original conception of the work was that genetic determinants of the sulfoxide/sulfone/sulfonate/sulfate ( 4S'') pathway in Pseudomonas spp. would be cloned in vivo and then transferred to Thiobacillus spp. This ambition remains an appealing prospect; however, fulfilling that ambition has been confounded by an instability observed in the DbtS{sup +} phenotype in Pseudomonas spp. But the persisting interest in the phenotype has lead to isolation of fresh strains which have a DbtS{sup +} phen… more

A novel coal feeder for production of low sulfur fuel

Description: In this project, a dual-screw feeder was designed for desulfurization of coal. The key parts of this reactor are two screw tubes which are used to feed coal and calcined lime particles separately, the inner tube acting as a coal pyrolyzer and the outer tube acting as a desulfurizer with hot calcined lime pellets or other renewable sorbent pellets. The objective of this project is to study the feasibility of an advanced concept of desulfurization in the coal feeder. (VC)

Amended Silicated for Mercury Control

Description: Amended Silicates{trademark}, a powdered, noncarbon mercury-control sorbent, was tested at Duke Energy's Miami Fort Station, Unit 6 during the first quarter of 2006. Unit 6 is a 175-MW boiler with a cold-side electrostatic precipitator (ESP). The plant burns run-of-the-river eastern bituminous coal with typical ash contents ranging from 8-15% and sulfur contents from 1.6-2.6% on an as-received basis. The performance of the Amended Silicates sorbent was compared with that for powdered activated … more

Electronic Surface Structures of Coal and Mineral Particles

Description: Surface science studies related to tribocharging and charge separation studies were performed on electrostatic beneficiation of coal. In contrast to other cleaning methods, electrostatic beneficiation is a dry cleaning process requiring no water or subsequent drying. Despite these advantages, there is still uncertainty in implementing large scale commercial electrostatic beneficiation of coal. The electronic surface states of coal macerals and minerals are difficult to describe due to their che… more

The fate of sulfur in mild gasification liquids

Description: This investigation addresses the determination of sulfur distribution in mild gasification liquids produced from untreated coal and from modified in two ways to reduce sulfur in the products: (a) physical mixing with a sulfur scavenger (CaO), and (b) pretreatment with aqueous alkali followed by mixing with CaO. Coal pyrolysis in the presence of CaO has previously been investigated, (3,5) showing that CaO can be effective in reducing the sulfur content of the fuel gas, and possibly that of the p… more
