Anthracite coal has the highest percentage of carbon among the different types of coal.
Anthracite has the highest energy
The sulfur content of coal and its heating values are not constant across all grades of coal. It would require information of type of coal, carbon content, sulfur content and ash content to even start the calculation.
Anthracite coal
Anthracite coal has been through low-grade metamorphism to become the highest grade of coal. This type of coal has the highest carbon count and the fewest impurities of any other type of coal.

Coal is a type of fossil fuel. If it sits for a long time under a lot of pressure coal can form diamonds. Coal also can be used on a simplistic level, in a barbecue grill for heating food.
Probably any other type of heating oil though you will lose capacity due to the different (lower) btu rating of other grades of heating fuel oil.
heating water to use in a boiler system type heating system raising the temperature of coal so that it will burn without any further combustant
The sulfur content of coal and its heating values are not constant across all grades of coal. It would require information of type of coal, carbon content, sulfur content and ash content to even start the calculation.
Very hard coals such as anthracite were formed under these conditions.
