What is petroleum
Petroleum, also known as crude oil, is a fossil fuel. It was formed from the remains of plants, algae, and bacteria. During millions of years of extreme heat and density, they were transformed into carbon rich resources which are the raw material for fuel and other products.
Petroleum is a mixture of hydrocarbons and paraffin in some cases and in other aromatics and cycloparaffins. Usually found in deep rock strata but sometimes near the earth’s surface. When it is mined, and refined, hundreds of petrochemicals are made into many different products.
Crude petroleum is made of approximately 80% carbon compounds, and a combination of hydrogen, nitrogen, oxygen, and sulfur.
