... natural gas availability (in certain regions) will bring into scene Gas-To- Liquids (GTL) derived fuels. The incorporation of natural gas as a refining feedstock would be the result of a preference for building specific molecules instead of cracking (less selective) the large ones. Fuel consumption is the...
