What if they hit on an equivalent of the Karrick process
From wiki and elsewhere....
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 m3) of rich
coal gas and 1,500 pounds (680 kg) of solid smokeless
char or semi-coke (for one
metric ton, 0.175 m³ of oils and coal tars, 95 m³ of gas, and 750 kg of semi-coke). Yields by volume of approximately 25%
gasoline, 10%
kerosene and 20% good quality
fuel oil are obtainable from coal. Gasoline obtained from coal by the Karrick process combined with cracking and refining is equal in quality to
tetraethyl lead gasolines. More power is developed in internal combustion engines and an increase in fuel economy of approximately 20% is obtainable under identical operating conditions.
