Petroleum products are the outputs of a petroleum refinery. A typical refinery produces a wide variety of different products from every barrel of crude oil that it processes. Generally, refineries operate to make as much of the high-value light products (gasoline, jet fuel, and diesel) that they can, with the other products acting essentially as byproducts.

Some of the major products from a typical refinery are:

Propane - Used as a feed stock for ethylene cracking, or blended into LPG for uses as a fuel

Butane - Used as a feed stock for ethylene cracking, or blended into LPG for uses as a fuel

LPG (liquified petroleum gas) - a blend of propane and butane used as fuel.

Light naphtha - used as feed stock into ethylene crackers.

Gasoline - used as a transportation fuel for passenger cars and light trucks.

Aviation gasoline - used as an engine fuel in light aircraft

Jet fuel - used as a fuel for jet aircraft

Kerosene fuel oil - used as a residential cooking, heating and lighting fuel

Diesel - used as a fuel for heavy duty trucks, trains, and heavy equipment.

Industrial gasoil - used as a furnace fuel in industrial plants and commericial/residential heating (heating oil)

Residual fuel oil - used as a fuel in power generation and for on large ocean-going ships (bunker fuel).

Many refineries also produce specialty or non-fuel products such as:

asphalt - used to pave roads and in the manufacture of building materials (e.g., roof shingles)

base oils - used to make lubricating oils for use in industrial machinery and vehicle engines

propylene - can be separated for sale to the petrochemicals industry

aromatics - can be separated from reformate for sale to the petrochemicals industry

wax - extracted from lubricating oil and either sold as a feed stock to specialty wax production (as slackwax) or treated at the refinery to a finished wax product.

grease - Used as a solid lubricating oil, mostly in industrial uses

white oil - a colorless, odorless, tasteless oil used by the food, cosmetics, and pharmaceuticals industries

white spirit - naphtha range material used as an industrial or household solvent

sulfur - a contaminant when present in other products, but once separated, it can be sold as a feed stock to the petrochemicals industry

pet coke - a byproduct of the coking process that can be sold as a fuel for power plants and cement plants or to manufacture electrodes and anodes
