Propylene (propene) is one of the most important feedstocks in the chemical industry. It is a starting material for the synthesis of a wide variety of commodity chemicals ranging from small molecules (cumene, isopropanol, acrylonitrile, acrylic acid, propylene oxide, and butyraldehyde) to polymers (most notably, polypropylene). In 2013, approximately 85 million tons of propylene were processed ...

A series of vanadia catalysts supported on the mesoporous silica SBA-15 are synthesized using an automated laboratory reactor. The catalysts contain from 0.6 up to 13.6V atoms/nm and are structurally characterized by various techniques (BET, XRD, SEM, TEM, Raman, IR, UV/Vis). Samples containing up to 3.1V/nm are structurally rather similar. They all contain a mixture of tetrahedral (VOx)n speci...

The effect of Ga, V, and Zr content on the structural properties catalytic behavior H-ZSM-5 monolithic catalysts-supported gallium oxide, vanadium zirconium oxide in oxidative dehydrogenation propane (ODHP) have been investigated a continuous tubular microreactor using CO2 as mild oxidant. SEM-EDX confirmed homogeneous distribution metal oxides within printed oxide/H-ZSM-5 catalysts ODHP reacti...

Carbon dioxide (CO2) assisted oxidative dehydrogenation of propane over Ga-modified catalysts is highly sensitive to the identity support, but underlying cause support effects has not been well established. In this article, SSZ-13, SSZ-39, ZSM-5, silica and γ-Al2O3 were used load Ga species by incipient wet impregnation. The structure, textural properties, acidity Ga-based process CO2-assisted ...
