In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.

Alkenes cause instability of hydrocarbon fuels. [9] Fluid catalytic cracking is a commonly used process, and a modern oil refinery will typically include a cat cracker, particularly at refineries in the US, due to the high demand for gasoline. [10] [11] [12] The process was first used around 1942 and employs a powdered catalyst. During WWII ...
The C 3-benzenes are a class of organic aromatic compounds which contain a benzene ring and three other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers. The chemical formula for all the saturated isomers is C 9 H 12.
It is composed of hydrocarbon molecules that typically contain between 6-20 carbon atoms per molecule, [12] predominantly containing 9 to 16 carbon atoms. [ 13 ] Regardless of crude oil source or processing history, kerosene's major components are branched- and straight-chain alkanes (hydrocarbon chains) and naphthenes (cycloalkanes), which ...
C 6 H 12 O 6 → 3 CH 4 + 3 CO 2. These hydrocarbon deposits, collected in porous rocks trapped beneath impermeable cap rocks, comprise commercial oil fields. They have formed over millions of years and once exhausted cannot be readily replaced. The depletion of these hydrocarbons reserves is the basis for what is known as the energy crisis.
Structure of C 17 H 20, which contains seven spiro atoms and eight cyclopropane rings [1]. In organic chemistry, spiro compounds are compounds that have at least two molecular rings sharing one common atom.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
