Propene epoxidation over Au/Ti-SBA-15 catalysts

The epoxidation of limonene over the TS-1 and Ti-SBA-15 catalysts.

Limonene belongs to a group of very important intermediates used in the production of fine chemicals. This monoterpene compound can be obtained from peels of oranges or lemon which are a (biomass) waste from the orange juice industry. Thus, limonene is a renewable, easy available and a relatively cheap compound. This work presents preliminary studies on the process of limonene epoxidation over ...

Direct Epoxidation of Propene over Goldtitania Catalysts: a Transient Study of the Reaction Mechanism

Gold-titania based catalysts for the direct epoxidation of propene provide a clean and simple route for future propene oxide producing processes. These catalysts, producing propene oxide in a single step, have a moderate activity and a very high selectivity towards propene oxide. However, the hydrogen, which is used as a co-reactant, is used less efficient. To be able to improve the hydrogen ef...

Catalytic epoxidation of styrene and methyl oleate over peroxophosphotungstate entrapped in mesoporous SBA-15

Methyl oleate deoxygenation for production of diesel fuel aliphatic hydrocarbons over Pd/SBA-15 catalysts

BACKGROUND Catalytic deoxygenation is a prominent process for production of renewable fuels from vegetable oil. In this work, deoxygenation of technical grade methyl oleate to diesel fuel aliphatic hydrocarbons (C15 - C18) is evaluated with several parameters including temperature, hydrogen pressure and reaction time in a stirred batch reactor over Pd/SBA-15 catalysts. RESULTS Two different S...

Dehydrogenation of Isobutane with Carbon Dioxide over SBA-15-Supported Vanadium Oxide Catalysts

A series of vanadia catalysts supported on SBA-15 (V/SBA) with a vanadia (V) content ranging from 1% to 11% were prepared by an incipient wetness method. Their catalytic behavior in the dehydrogenation of isobutane to isobutene with CO2 was examined. The catalysts were characterized by N2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and temperatur...
