In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking … Zobraziť viac Among several variants of thermal cracking methods (variously known as the "Shukhov cracking process", "Burton cracking process", "Burton-Humphreys cracking process", and "Dubbs cracking process") Zobraziť viac Outside of the industrial sector, cracking of C-C and C-H bonds are rare chemical reactions. In principle, ethane can undergo homolysis: CH3CH3 → 2 CH3• Because C-C bond energy is so high (377 kJ/mol), this … Zobraziť viac • Information on cracking in oil refining from howstuffworks.com • www.shukhov.org/shukhov.html — Vladimir Grigorievich Shukhov biography Zobraziť viac Thermal cracking Modern high-pressure thermal cracking operates at absolute pressures of about 7,000 kPa.
