underground gasification

Coal utilisation can also include the non-conventional method of its underground gasification.

Daedalus now proposes, not the underground gasification of coal, but its underground polymerization.

Why is it that the first and second phases of planned underground gasification demonstration plants are to be made in Spain and Belgium?

In 1979-1981, an underground gasification of steeply dipping seams was demonstrated near Rawlins, Wyoming.

Proposed uses for the device included drilling shallow holes for mineral exploration, construction, underground gasification of coal, water and methane drainage.

Reliance Energy is working on establishing power generation through underground gasification technique in Barmer district with an outlay of about 3000 crore rupees.

China's coal washing and dresing technologies and abilities have constantly improved and coal liquefaction and underground gasification are being introduced.

Fredrik Ljungström also invented a technology for oil shale underground gasification by electrical energy (Ljungström method) and made several inventions related to sailing boats.

One of the earliest successful in situ processes was underground gasification by electrical energy (Ljungström method)-a process exploited between 1940 and 1966 for shale oil extraction at Kvarntorp in Sweden.

The earliest recorded mention of the idea of underground coal gasification was in 1868, when Sir William Siemens in his address to the Chemical Society of London suggested the underground gasification of waste and slack coal in the mine.

Given these existing constraints, government should support research and development of new ways of producing and using energy - more efficient power sources for transportation, like fuel cells, for example; carbon-free energy sources, like more advanced nuclear power plants and effective solar power systems; underground gasification of coal.
