The catalytic oxidative dehydrogenation (ODH) of light alkanes has great potential to be used for production of alkenes instead of classically used steam cracking of naphtha. We report for the first time a comparison of molybdenum oxide species suppo

In this work, we report successful preparation of hierarchical V-MCM-36 zeolitic catalyst. Vanadium was introduced onto the zeolite support by impregnation, using vanadyl acetylacetonate as a metal precursor and its subsequent solid state ion exchang

Three industrially important supports, SiO 2 , TiO 2 and Al 2 O 3 , were used for preparation of NiMo catalysts (3.3 wt.% Ni and 15.0 wt.% Mo) and used in deoxygenation of rapeseed oil in presence of hydrogen (3.5 MPa) at 260–300 °C and liquid fee
