A tonne of coal equivalent (tce), sometimes ton of coal equivalent, is a conventional value, based on the amount of energy released by burning one tonne of coal. Plural name is tonnes of coal equivalent. Per the World Coal Association: 1 tonne of coal equivalent (tce) corresponds to 0.697 tonne of oil equivalent (toe) [29] Per the International ...
Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals.This process is often known as "coal to X" or "carbon to X", where X can be many different hydrocarbon-based products.
One common such material is water, used in multiple units. For the cubic ton, the situation is more complex—there are different cubic tons for different materials. The 1964 Reader's Digest Great Encyclopaedic Dictionary gave the following ton-derived volumes: Timber, 40 cubic feet or 480.0 bd ft or 1.133 m 3; Stone, 16 cubic feet (0.453 m 3)
Coal can be converted directly into synthetic fuels equivalent to gasoline or diesel by hydrogenation or carbonization. [100] Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. Mixing in biomass and using carbon capture and storage (CCS) would emit slightly less than the oil process but at a high cost. [101]

In the Karrick process, 1 short ton of coal yields up to 1 barrel of oils and coal tars (12% by weight), and produces 3,000 cubic feet (85 m 3) of rich coal gas and 1,500 pounds (680 kg) of solid smokeless char or semi-coke (for one metric ton, 0.175 m 3 of oils and coal tars, 95 m 3 of gas, and 750 kg of semi-coke).
The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil. It is approximately 42 gigajoules or 11.630 megawatt-hours , although as different crude oils have different calorific values , the exact value is defined by convention; several slightly different definitions exist.
