Theoretical Simulation of n-Alkane Cracking on Zeolites

WebDec 26, 2015 · Industrially, this process is done by first creating synthesis gas (CO + H 2) from methane by partial oxidation using pure oxygen (which is cryogenically separated from air). Thereafter, the synthesis gas is compressed to roughly 20 atm of pressure and converted to very long hydrocarbons (waxes) in the Fischer-Tropsch process. WebAlkanes are saturated hydrocarbons. They have the C-Cfunctional group and the general formula C n H 2n+2. They are named using standard nomenclature rules and the suffix -ane. Long-chain alkanes are found in crude oil. We can produce short-chain alkanes by cracking these longer molecules, and also synthesise alkanes by hydrogenating alkenes. flag of nato
