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

Preparation and Catalytic Properties of Ti-SBA-15 Mesoporous Materials

Ti-SBA-15 mesoporous materials were directly synthesized via a hydrothermal process and characterized by using nitrogen adsorption-desorption measurements, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, diffuse reflectance ultraviolet-visible spectroscopy, and infrared ray spectroscopy. The effect of synthesis temperatures on the structure and catalytic effic...

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...

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 ...

A study on the catalytic activity of a new acidic ordered mesoporous silica (SBA-15)

SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a large surface area, which is widely employed as a catalyst. This mesoporous silica due to silanol groups is easily functionalized by various organic materials. A new acidic ordered functionalized mesoporous silica (SBA-15-Aminopropyl-Benzyl-SO3H) has been introduced as an efficient catalyst for ...
