And it’s going to get worse as new technologies to convert natural gas into motor fuels start to come online in the next decade. Unlike the Fischer-Tropsch process to convert coal to liquid fuel, the gas-to-liquid conversion process results in extremely pure forms of gasoline (petrol) and diesel fuel that burn far more cleanly, which also means lower air pollution.
Do you understand that process goes to gas first, then to liquid? The Sulfur, ash, etc is removed before the liquid fuel is made.
Coal to liquid does not carry all the impurities into the liquid fuel.
