Title: Preparation of olefin from natural gas
Inventor: SHIYARURU KAMERON
IPC: C07C11/04
Filed: 1990-01-16
Abstract: PURPOSE: To obtain olefin effectively, by oxidative pyrolysis of natural gas utilizing methane, ethane and propane efficiently.  
     CONSTITUTION: A natural gas flow 2 is separated into a fraction 3 enriched with methane and a fraction 4 enriched with higher hydrocarbons by a separator 1, and a gas flow 3 is previously heated and mixed with molecular oxygen 6 to obtain an effluent containing mainly C 2  hydrocarbons and water. A gas flow 4 is separated into a fraction 9 enriched with propane and a fraction 7 enriched with ethane. Pyrolysis is carried out by mixing a gas flow 7 with the effluent when at least 80% by volume of the molecular oxygen has already been consumed in the above stage. When the effluent has an olefins/C 2  alkane in a molar ratio of at least 0.5, a gas flow 9 is mixed for pyrolysis. An effluent from a reactor 10 is collected by rapid cooling, or after removal of CO 2 , the effluent is subjected to methane formation, so that CO and H 2  are converted into CH 4  and H 2 O and they are recycled.
