11.11-2 EMISSION FACTORS 2/80
11.11 Coal Conversion. In addition to its direct use for combustion, coal can be converted to organic gases and liquids, thus allowing the continued use of conventional oil- and gas-fired processes when oil and gas supplies are not available. Currently, there is little commercial coal conversion in the United States.

1 INTRODUCTION. Coal liquefaction syncrudes derived from a variety of Australian coals (lignite, sub-bituminous, bituminous) and a number of different coal liquefaction processes have been produced at these laboratories. To produce acceptable quality transport fuels from coal liquefaction syncrudes, hydrotreatment of the syncrude is essential.

Burn raw coal at all times. Don't use coal cracking for anything else than direct use of heavy oil or direct conversion to petrol. If you need extra petrol, the most resource effective priority is to crack ALL your existing oil and burn coal and only crack surplus coal to make more petrol. Edit: Rechecking taxes again.
