Question

carbon content in crude oil

Answer 1

Petroleum (from Ancient Greek: petra: "rock" + oleum: "oil"[1][2][3][4][5][6]) is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column.

Answer 2

Liquid petroleum pumped from oil wells is called “crude” or “crude oil.” Composed predominantly of carbon, crude oil contains approximately 84 to 87 percent carbon and 11 to 13 percent hydrogen. Crude oil also contains varying amounts of oxygen, sulfur, nitrogen, and helium.

The petroleum industry often names crude based on the oil's geographical source for example “West Texas Intermediate.” Crude oil is also classified based on physical characteristics and chemical composition, using terms such as “sweet” or “sour,” “light” or “heavy.” Crude oil varies in price, usefulness, and environmental impact.
