Conversion of LPG to light olefins on acidic SAPO-43 catalyst: a preliminary study

This paper deals with the preliminary results of an acidic SAPO-57 catalyst for light olefins production from LPG at 345 K under atmospheric pressure. An induction period was evident for the formation of propylene, with the maximum yield observed at the time-on-stream of 53 min. An approximate yield of 192 (by weight) of light olefins was achieved including ethylene and propylene at the peak time. However, the ethylene and propylene were replaced with acyclic β-olefins of four carbon atoms after the maximum propylene production
