Petroleum products are supplies derived from crude oil (petroleum) as it is processed in oil refineries. Not like petrochemicals, which are a group of properly-defined usually pure chemical compounds, petroleum products are complicated mixtures. The majority of petroleum is converted to petroleum products, which includes several classes of fuels.[1]

In keeping with the composition of the crude oil and relying on the demands of the market, refineries can produce totally different shares of petroleum products. The biggest share of oil merchandise is used as “vitality carriers”, i.e. varied grades of gasoline oil and gasoline. These fuels embrace or might be blended to give gasoline, jet fuel, diesel gasoline, heating oil, and heavier fuel oils. Heavier (much less unstable) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce different chemicals, a few of that are utilized in chemical processes to provide plastics and other useful materials. Since petroleum usually incorporates a number of p.c sulfur-containing molecules, elemental sulfur is also often produced as a petroleum product. Carbon, within the type of petroleum coke, and hydrogen may also be produced as petroleum products. The hydrogen produced is often used as an intermediate product for different oil refinery processes reminiscent of hydrocracking and hydrodesulfurization.
