What is the Cracking of Hydrocarbons?
After the fractional distillation
of crude oil
there are too many
large hydrocarbons and not enough small hydrocarbons
to meet the public's demand.
Some of the large hydrocarbons (the heavier fractions)
are broken down into more useful smaller hydrocarbons
(lighter fractions) by a process known as cracking.
of cracking results in the formation
of smaller, more useful alkanes (such as petrol),
and even more useful alkenes (such as ethene).
The fractional distillation of crude
oil produces alkanes.
Cracking is the main source of alkenes.
See also the dehydration of ethanol to produce ethene.
