Butane–butylene fraction cracking over modified ZSM-5 zeolite

Altynkovich, E. O. / Potapenko, O. V. / Sorokina, T. P. / Doronin, V. P. / Gulyaeva, T. I. / Talzi, V. P.

Abstract The effect of temperature (530–590°C), weight hourly space velocity (2.5–7.0 h–1), and the Si/Al ratio of the ZSM-5 zeolite (30, 55, 80, 300) on the cracking of a butane–butylene fraction containing 85 wt % butylenes has been studied. The HZSM-5 zeolite has been modified with phosphorus. The effect of modification on the catalyst activity in cracking reactions has been studied. The ethylene and propylene yield achieves 38.4 wt % at a degree of conversion of butylenes of 81.5%. The ethylene to propylene ratio is 0.55.
