Cracking (chemistry) Wikipedia

In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or longchain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carboncarbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts.
