Executive Summary The Clean Coal Technology (CCT) Program is a government and industry cofunded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a scale sufficiently large to demonstrate commercial worthiness and to generate data for design, construction, operation, ...

Four different coals were studied using a combination of T2, T1, FID and solid echoes measurements on saturated plugs and degassed cuttings. These measurements were performed on two NMR spectrometers working at a proton Larmor frequency of 2 and 23 MHz. The measurements on saturated plugs allow the characterization of the cleats, and the measurements on degassed cuttings allow the characterisat...

The interstellar absorption band centred on 2175 Å that is conventionally attributed to monodisperse graphite spheres of radii 0.02 mm is more plausibly explained as arising from biologically derived aromatic molecules. On the basis of panspermia models, interstellar dust includes a substantial fraction of biomaterial in various stages of degradation. We have modeled such an ensemble of degrade...

Biofuel pellets were prepared from biomass (pine, chestnut and eucalyptus sawdust, cellulose residue, coffee husks and grape waste) and from blends of biomass with two coals (bituminous and semianthracite). Their mechanical properties and combustion behaviour were studied by means of an abrasion index and thermogravimetric analysis (TGA), respectively, in order to select the best raw materials ...

Th e electricity generating effi ciency is the energy in the net electricity generated divided by the energy in the fuel used to generate that electricity on an all-in basis. Higher effi ciency means less coal consumed and reduced emissions per unit of electricity. Th e chemical energy in the fuel can be expressed as either its Lower Heating Value (LHV) or its Higher Heating Value (HHV) [5]. In...
