Underground coal gasification

Before the Indonesian government pumps money into gasification, they might want to take a look at what happened in the U.S. not so long ago. Back in the 2000s, the American coal industry was pushing to build gasification plants to turn coal into a liquid gas that, they claimed, could be used in chemicals and even for transportation as an alternative to imported oil and then …

New Energy Frontier: Drilling Into Coal for Gas

Publisher Summary. Coal is used primarily as a fuel, so its most important property is its heat of combustion. Gross calorific value, also known as higher heating value (HHV), is determined by measuring the heat released when coal is burned in a constant-volume calorimeter, with an intitial oxygen pressure of 2 to 4 MPA, and when the combustion products are cooled to a final …

Poland is the largest producer of hard coal in the European Union (63 million tons in 2018), and coal is the basis of Poland's power generation mix - 86% of electric power is produced by coal-fired power plants. Coal gasification technology, production of syngas from hard coal, is considered by the government as an opportunity for Polish coal ...

Coal gasification | coal processing | Britannica

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.
