Effect of temperature on propylene and ethylene production from LPG pyrolysis

This paper deals with the effect of temperature on the production of light olefins (propylene and ethylene) in the temperature range of 500–750 °C. The light olefins were found to be ~41% (by weight) at 750 °C excluding butenes or butadiene from olefins. Although propylene yields were always greater than ethylene yields, this precedence was reversed at ~730 °C after which propylene production decreased in favor of an ethylene enhancement. In summary, the reactions were intensified after 700 °C which led also to increased methane and ethane yields, but not very pronounced C5+ species in the range investigated.
