Petroleum (or crude oil) is a complex, naturally occurring liquid mixture containing it is possible to separate each component of petroleum one-by-one, though. The ratio of the different constituents in crude oils, however, vary appreciably from one reservoir to another. Normally, crude oils are not used directly as fuels or  16 Jul 2013 PDF | Crude oil hydrocarbon composition characteristics and oil viscosity Crude oil is a complex and multi-component homogeneous. and oxygen combined with carbon and hydrogen are also found. – The major constituent of petroleum is Alkane which is a homologous series of hydrocarbons . often blends of different crude oils, and the relative proportions of component oils frequently change. Therefore, the physical and chemical properties will vary.

The petroleum fuels are a group of hydrocarbons refined and modified from the crude oil, and include more than 100 kinds of aliphatic and aromatic
