Both the preparation and the characterization of vanadyl pyrophosphate (VPO) supported on new heat-conductive ceramic supports (β-SiC, Si 3 N 4 , and BN) are described. These catalysts provide a very significant gain in maleic anhydride yield by rea

An experimental study was performed to investigate the effect of sieve trays on the time-averaged gas holdup profiles and the overall gas holdup in a cold-flow bubble column that was scaled-down from a commercial unit. γ-ray computed tomography (CT)

Vinyl acetate can be formed in the homogeneous reaction of ethylene with palladium acetate in glacial acetic acid. We propose a Wacker-like mechanism, which has been studied using density functional theory computational methods. The palladium acetate

We have studied the various aspects of the homogeneous acetoxylation of ethylene to vinyl acetate by palladium acetate using ultraviolet-visible (UV/vis), Raman, and infrared spectroscopic methods. Vibrational assignments for the Raman and the infrar

The application of supported liquid-phase catalysis (SLPC) to selective oxidation examples is discussed to provide valuable alternatives to the purely homogeneous or heterogenous processes. Specific examples discussed are the Wacker type ethylene oxi

A method initially developed for the synthesis of high surface area carbides using volatile metallic precursors was successfully adapted to the preparation of high surface area vanadium carbide using a liquid precursor. The method consists of reactin
