I don't have the answer
In 2003, excluding lignite, total of 5,118,800,000 tons of coal was produced around the world.
To convert coal into coke, the coal is burned in an oxygen-depleted environment. When this happens, the impurities of the coal are burnt up but the carbon remains. This is why coke is much lighter than coal.
Coal does not get refined. Oil gets refined, but coal gets used as it is when it comes out of the coal mine. There is a process called coal gassification by which natural gas can be made from coal, but that is not really a form of refining, and in any event, most coal is simply burned, it is not gassified.
From <28470 kJ/kg to about 35380 kJ/kg, depending on the kind of coal and how efficiently it is burned. The figures assume 100% efficiency, which is never reached.
Lignite, often referred to as brown coal, is a soft brown fuel with characteristics that put it somewhere between coal and peat. It is often burned in power stations constructed very close to any mines.
The Titanic burned a total of 3,540 tons of coal, averaging 620 tons of coal per day at 21.7 knots. The Titanic had 5,892 tons of coal in approximate measure when she departed Southampton.
Pure coal (?) , None, just CO2.

About 1500 tons of coal
India has the fourth largest coal reserves in the world. They have a lot of coal!

Non, because Titanic didn't use fuel. She used coal, instead of fuel.
2 Trillion pounds a year in 2007 with a annual growth of 3%.

Depends on the size of your pellet. 1 kg of Uranium235 is equivalent to 1500 tonnes of coal.
