Asphaltic crude Petroleum with a high content of naphthenic compounds, such as asphaltenes. Asphaltic crude is also known as naphthene-based crude oil when the paraffin wax content is low. This type of oil is suitable for making gasoline, lubricating oil and asphalt.
Paraffinic Crude For a waxy crude it is customary to measure its cloud point and pour point according to ASTM methods. Crude petroleum oil that contains predominately alkanes as contrasted with asphaltic- or naphthenic-base crudes; used as a source of fuels and high-grade lubricating oils. the dynamic viscosity of crude oil increased with the increase of paraffinic content in crude oil.
Fractions of Paraffinic crude Distillate: Gas gasoline kerosene diesel Residue (Fuel Oil): Wax (lubricating oil), Residue

Bitumen & Bituminous coal Bitumen: Any of various flammable mixtures of organic liquids (aromatic), occurring naturally or obtained by distillation from coal or petroleum, that are a component of asphalt and tar and are used for surfacing roads and for waterproofing. bituminous coal: a dark coal that burns easily with a smoky flame yielding pitch or tar: also called soft coal
Liquid fuels for the furnace Gas oil Heavy fuel oil Light fuel oil Coal tar fuel
Fuels Oils Fuel oil is made of long hydrocarbon chains, particularly alkanes, cycloalkanes and aromatics. Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue. The heaviest commercial fuel that can be obtained from crude oil, heavier than gasoline and naphtha is also fuel oil.
Fuels Oils Distillate Fuel Oils: A general classification for the petroleum fractions produced in conventional distillation operations. used for space heating on and off highway diesel engine fuel (including railroad engine fuel and fuel for agricultural machinery) and electric power generation.
Fuels Oils Included are products known as No. 1, No. 2, and No. 4 fuel oils and No. 1, No. 2, and No. 4 diesel fuels. No. 1 distillate is a petroleum distillate which meets the specifications for No. 1 heating or fuel oil as defined in ASTM D 396 and/or the specifications for No. 1 diesel fuel as defined in ASTM D 975.
Light Fuel Oils Streams obtained from distillation and cracking processes . Contain a mixture of saturated, aromatic and olefinic hydrocarbons with carbon numbers predominantly in the C9 to C30 range. Composition is complex and varies with the source of the crude oil. Extremely flammable. Flash Point <620C typical boiling range from 150 to 550°C.
Heavy Fuel Oils viscous liquids with a characteristic odour. require heating for storage and combustion. used in medium to large industrial plants, marine applications and power stations in combustion equipment such as boilers, furnaces and diesel engines. typical boiling range from 350 to 650°C. They consist of aromatic, aliphatic and naphthenic hydrocarbons, typically having carbon numbers from C20 to C50,
