There’s a huge difference. One is to use coal as the main raw material and directly (indirectly) liquefy it to produce oils such as diesel and lubricating oil ； The other method uses coal as a raw material to produce coke or blue carbon, and the by-product coal tar is converted into fuel oil through hydrogenation. Both production methods have demonstration projects and mature processes.
Coal-to-oil is a process that uses coal as the main raw material to directly (or indirectly) liquefy it in order to produce oils such as diesel, lubricating oil, and fuel oil； Coal tar hydrogenation uses coal tar, a by-product of the coal coking process, as raw material to produce fuel oil through hydrogenation. Both production methods have demonstration projects and mature processes.
