The reaction mechanism of the direct conversion of ethylene to propene over Ni-containing catalysts is assumed in literature to comprise (i) ethylene dimerization to 1-butene, (ii) butene isomerization and (iii) metathesis of 2-butene with ethylene t

Non-oxidative propane dehydrogenation (PDH) was investigated over unconventional catalysts, i.e. binary La2O3-ZrO2 and Y2O3-ZrO2 materials with or without tiny amounts (0.005 or 0.05 wt.%) of Ru in form of nanoparticles with the size of about 1.1 nm.

Non-oxidative dehydrogenation of isobutane was investigated over VO x /MCM-41, VO x /Al 2 O 3 and VO x /SiO 2 –Al 2 O 3 (1–70 wt.% SiO 2 ). The highest selectivity to isobutene of around 85% at isobutane conversion of 50% was achieved over VO x /
