Parameters can be adjusted to avoid directly gasifying any of the coal entering the plant.

But energy experts predict that another approach may become even more environmentally important: gasifying a "renewable" fuel like wood.

The other potential lignite-conversion project is to gasify lignite to produce liquid fuels.

Indeed, gasifying coal could be economically attractive in the United States in the near future, many energy experts say.

In 1785 Minckeleers used some of this apparatus to gasify coal to light his lecture hall at the university.

With Government subsidies, Texaco has also shown promising results in gasifying high-sulfur coal.

You left out shale gas, coal bed gas and the opportunity to gasify coal underground.

The main feature is that instead of using oxygen and nitrogen to gasify coal, they use oxygen and CO.

In 1920s, the Winkler process was developed to gasify coal in a fluidized bed, using oxygen.

Wilbur L. Ross Jr., the company's chairman, said he was exploring whether to gasify those reserves for use as feedstock.

(22) The term "gasify" means to convert carbon-containing material into a gas consistingprimarily of carbon monoxide and hydrogen.

In the near term, he said, the Energy Department believes other coal technologies may be competitive first, including gasifying coal and using it in a turbine.

In 1905, it bought a controlling interest in Penn Gas Coal, a company established in 1861 to gasify coal.

But Texaco has been commercially successful in gasifying less valuable hydrocarbons, notably heavy crude oil that is generally difficult to burn because of its high sulfur content.

The process works by gasifying Refuse derived fuel (RDF) to create a synthetic gas or syngas which contains soot and tars.

The plant, in the Mojave Desert, aims to use the US's most abundant fuel - coal - as a 'clean' energy source for power generation by gasifying it.

The investigators also found natural-gas lines installed - above ground and without protection - beneath the terminal's fresh-air intake ventilation system, meaning that a leak there could gasify the whole building.

Likewise energy companies are stepping up research and investments into oil sands, deep-ocean oil and gas drilling, and gasifying and liquefying coal - all with significant environmental consequences.

"You can't justify it, especially as other sources of energy look better and better, as people find better ways to gasify coal and build fission reactors" that are safer.

This will be the world's first LNG terminal able to import and gasify LNG and Liquefy and export natural gas.

And today some companies gasify heavy oil; others are trying to gasify tougher substances, like tires that have been cooked in an oil stew to prepare for gasification.

A Texaco coal gasification plant, originally located in Cool Water, California, was disassembled, refurbished and its technology converted to be able to gasify petroleum coke instead of coal.

The Bill & Melinda Gates Foundation is investing in research at Delft University to design a self contained toilet that uses microwaves to create plasma and gasify human waste.

While biodiesel and bio-ethanol production so far only use parts of a plant, i.e. oil, sugar, starch or cellulose, BtL production can gasify and utilize the entire plant.

Drying grains and peas, roasting coffee beans, gasifying coals, and some roasting metal ores are such solids, and they are usually processed in shallow beds or in the spouting mode.
