Production of propylene from an unconventional metathesis of ethylene and 2-pentene over Re2O7/SiO2-Al2O3 catalysts

NaOH modified WO3/SiO2 catalysts for propylene production from 2-butene and ethylene metathesis

“…Due to the rising demand for propylene in the petrochemical industry, the metathesis of 2-butene and ethylene is now used for on-purpose propylene production [1,2]. Several catalysts including supported MoO3 [3,4], Re2O7 [5][6][7], and WO3 [8][9][10] are known to catalyze the reaction. Industrially, the WO3/SiO2 system is the most common.…”
