You need to be more specific. I use Naphtha as fuel every day when I drive to work. It consists mainly of desulfurized Naphtha from our crude units, Full Range Cracked (FRC) from our Cat Cracker, Alkylate from our Sulfuric Acid Alkylation unit, Platformate from our Platformer, mixed with various other blending stock from our Powerformer, Penex, Dimersol and Poly units. It has Butane added for cold start capability in winter.
