Burning coal to generate electricity is one of the key sources of atmospheric carbon dioxide emissions; so, targeting coal-fired power plants offers one of the easiest ways of reducing global carbon emissions. Given that the world's largest economies all rely heavily on coal for electricity production, eliminating coal combustion is not an option. Indeed, coal consumption is likely to increase ...

Use of gasification based on dirty fuels in markets other than syngas production for downstream chemical processes is emerging due to market changes associated with improved gas turbines, deregulation of electric power generation, as well as more and more stringent environmental regulations. Especially for the increasing quantities of opportunity fuels such as refinery residues, biomass and som...

Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to produce synthetic fuels when there was no oil allowed into the country. Since then, it has been studied in the United States and many different technologies have been investigated. Since the US is rich in coal resources, this is one way to be energy independent. Most of the dev...

Program is a joint effort between government and industry to develop a new generation of coal utilimtion processes. In 1986, the Ohio Power Company, a subsidiary of the American Electric Power Service Corporation (AEP), was awarded cofunding through the CCT program for the Tidd Pressurized Fluidixed Bed Combustor (PFBC) Demonstration Plant located in Brilliant, Ohio. The Tidd PFBC unit began op...

A US-led six-nation pact to develop clean energy technologies and combat global warming was launched last month with its members denying it was designed to undermine the Kyoto protocol on emission reductions. But without targets for reductions in greenhouse gas emissions, many researchers were disappointed. And the announcement came as new evidence suggests several species of north Atlantic bir...

The Yangquan coalfield is one of the typical highly gassy mining areas in China. However, its coal seams are of lower permeability, which are not conductive to coalbed methane (CBM) drainage. In this study, based on the theory of the ground movement, we analyzed the principle of coal and CBM coextraction in the Yangquan coalfield, and established the technology system of coal and CBM coextracti...
