The experiment involved heating coal samples from six coalbeds at constant temperatures and analyzing evolved gases. The composition of the gases at three temperatures was compared. At 35" C, over 99 pct of the gas is methane; at 125" and 150°, methane constitutes approximately half of the hydrocarbon gas.
The power plant has six units that will together generate 4,800MW. The first unit (Unit6) was synchronised to the grid in March 2015 and is being commissioned as of July.. The plant will be the world's biggest drycooled, coalfired power station, as well as the world's fourth biggest coalfired power plant, when fullyoperational.
