Effect of Inherent Moisture in Collie Coal during ...

The influences of inherent moisture in Collie coal during pyrolysis has been studied using a series of Collie coal samples, including the raw coal, dilute acid-washed coal, and demineralized coal samples of both pulverized fuel and millimeter sizes. Coal without drying (moisture content ∼ 20%) and dried coal (moisture < 1%) were pyrolyzed under various conditions in a fixed-bed reactor, a ...

The coal gasification is expected to cut spending on imported oil by $7 billion per year. Industry Minister Airlangga Hartarto said the new strategy would utilize gasification technology and aims to convert low-calorie coal into synthetic gas, which is the main component for producing dimethyl ether for liquid petroleum gas substitute, urea for fertilizer and polipropilena for plastics.

Coal gasification commercialization - Wikipedia

Coal gasification is a process whereby a hydrocarbon feedstock (coal) is converted into gaseous components by applying heat under pressure in the presence of steam. Rather than burning, most of the carbon-containing feedstock is broken apart by chemical reactions that produce "syngas." Syngas is primarily hydrogen and carbon monoxide, but the exact composition can vary.

Coal gasification can also be carried out on seams that are still in place, the coal being converted to gaseous fuels without an intermediate mining operation. This process, known as in situ or underground gasification, typically involves drilling boreholes or sinking shafts to intersect the seam in at least two places and providing a passage for gas through the seam from one intersection to ...

Coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a by-product. Such coal gas was widely used for street lighting and home ...
