Steam Cracking - an overview ScienceDirect Topics
WebIn petroleum geology and chemistry, cracking is the process whereby complex organic molecules such as kerogens or heavy hydrocarbons are broken down into simpler molecules (e.g. light hydrocarbons) by the breaking of carbon -carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and ... In steam cracking, a gaseous or liquid hydrocarbon feed like naphtha, LPG or ethane is diluted with steam and briefly heated in a furnace without the presence of oxygen. Typically, the reaction temperature is very high, at around 850 °C, but the reaction is only allowed to take place very briefly. See more 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 … See more Thermal cracking Modern high-pressure thermal cracking operates at absolute pressures of about 7,000 kPa.
