In fact, according to the EIA "by the end of WWII, Germany 's nine indirect and 18 direct liquefaction plants were producing approximately 4 million tonnes of liquids per year, satisfying 90 percent of Germany' s total petroleum consumption".

The direct coal to liquids process was used to produce high quality gasoline, while the FT process yielded diesel fuel. The 1931 Nobel Prize in Chemistry was awarded to Friedrich Bergius for the development of the direct process.

I don't know of anybody using his process nowadays.

Looked it up om Wikipedia.  The process looks close to the H coal process that Exxon was examining once upon a time.  Looks like the Germans started from a syngas feedstock to get the required hydrogen.
