Yes, the elemental analysis of dried lignite and subbituminous coal such as found in Montana here := http://pubs.usgs.gov/bul/b2144/carbon.htm
gives the percent by weight of dry material as :=
Lignite                       64-65% Carbon;  4.2-4.3% Hydrogen; 1.3-1.4% Nitrogen
Subbituminous coal   56-57% Carbon;  3.7-3.8% Hydrogen; 0.93-1.2% Nitrogen

This gives 0.76 to 0.81 hydrogen atoms per carbon atom of dried coal. If you add 40% water the hydrogen content rises to 2.1 to 2.4 atoms per carbon atom. This is indeed close to the theoretically required ratio.

The disadvantage is that the carbon content of the wet coal is 34 to 39%. If the yield figures for coal to liquid conversion usually quoted are for dry high carbon coal then the yields this per ton of mined material will be much lower.

The promise is for a clean process. Let us hope that things have improved a lot but I have memories of the gas works in the UK that provided domestic gas when I was a boy before the discovery of North Sea natural gas. They produced from coal a mixture of about 50% explosive hydrogen and 15% poisonous carbon monoxide piped to houses often with no safety cut-outs. A delay in lighting the gas lamps would produce a bang that would shatter the mantle and scatter uranium soaked silk ash in your face. The gas works always stank. The nitrogen would form ammonia and amines and combine with the sulphur dioxide to give a stench I still clearly remember. Promises will doubtless be made but I wonder if they will be kept.
