  8. H H C H H H C H H C C C C H H C H Types of Oil • Carbon-Hydrogen Chains • 1-4 carbons light hydrocarbons, ex. Methane (CH4) • 4-14 carbons naptha ==> gasoline • 12-15 carbons kerosene ==> jet aircraft fuel • 15-25 carbons gas oil ==> heating oil and bunker fuel • >25 carbons residual oils • Carbon-Hydrogen Rings = Aromatics • Benzene C6H6 • Toluene C6H5CH3 • Xylenes C6H4(CH3 ) 2==> polyester
