Production of olefins via steam cracking of vegetable oils
Original language description
Vegetable oils (in Europe particularly rapeseed) are the favoured raw material for production of methyl esters to be used as biodiesel. This paper presents another possibility of their utilization as crude oil substitute. During thermal decomposition under conditions matching those of gas-oil steam cracking (short residence time, temperature over 800 °C) vegetable oils produce similar products as traditional crude-oil-based feedstocks. Using the apparatus employed previously to laboratory research of hydrocarbon pyrolysis, the yields of major pyrolysis products of various vegetable oils were determined and compared to those of traditional feedstocks. Also the effects of hydrocarbon chain length and saturation of acyls forming the oil triacyl glycerolswere analyzed in detail. The possibilities of processing vegetable oils by co-cracking in mixture with crude oil feedstocks are discussed and supported by experimental data.
