Heightened oil sands extraction by pressure cycles | 2009 | oil sands extraction; pressure cycles; hot water extraction of bitumen | Hot water extraction of bitumen from oil sands has been commercially applied for decades. The extraction process is greatly aided by the addition of caustics and other reagents, which can adversely impact handling and disposal at process end. Recent attention has been on increasing process efficienc... |

Investigation of coal char-slag transition during oxidation: Effect of temperature and residual carbon | 2009 | coal char; molten slag; bitumous coal; energy and fuels | The transition of coal char to molten slag at high conversion was studied for a bituminous coal using a laminar entrained-flow reactor under oxidizing conditions. Post-oxidized char particles were analyzed by various techniques including loss-on-ignition, gas adsorption analysis and scanning electro... |

Relationships between composition and pulmonary toxicity of prototype particles from coal combustion and pyrolysis | 2009 | toxicity; prototype particles; coal combustion; pyrolysis; health effects; coal combustion fly-ash particles | The hypothesis that health effects associated with coal combustion fly-ash particles are exacerbated by the simultaneous presence of iron and soot was tested through two sets of experiments. The first set created prototype particles from complete and partial combustion, or oxygen free pyrolysis of a... |
