Preliminary Study on Feasibility of Ethylene Production from Vegetable Oil by Steam Cracking

To find new materials which could partly substitute traditional feedstocks for ethylene production, several vegetable oils and swill-cooked dirty oils are pyrolysed under steam-cracking conditions. The properties and product distributions of peanut oil, sesame oil and soybean oil are compared with naphtha. The results showed that vegetable oils can give olefin yields near to naphtha under milder cracking conditions, which prove a potential utilization route for renewable energy.
