Two VPO materials with fibrillar morphology have been prepared by the aid of electrospinning technique. One is a VPO carbon-supported material (VCF200) with fibrous morphology and very high surface area that is stable under ...

Introduction. In the past decades, global warming resulting from the emission of greenhouse gases, consisting mainly of carbon dioxide and methane, has become one of society’s main concerns. In this context, there has ...

A numerical model describing transport of multiple species and chemical reactions during electrokinetic treatment is presented. The transport mechanisms included in the model were electromigration and electroosmosis. The ...

La conferencia versará sobre cuál es la estructura de una Refinería actual basada en el refino de Petróleo. Se abordarán aspecto generales técnicos y de estrategia que condicionan la operatividad y el rendimiento de la ...

Hydrogen is conventionally manufactured in large scale by the steam reforming of methane or naphthas. The perspective of using hydrogen as a fuel depends of finding alternatives to the existing production technologies and ...

In order to improve the catalytic formulations for soot removal in after-treatment emission control technologies for gasoline and diesel engine vehicle, an isotopic study was approached using transitory labeled oxygen ...

The growing concerns about climate change and energy consumption have been the driving force in seek of alternative fuels such as DME, mainly produced via methanol dehydration over a solid acid catalyst. The use of ...

A rigorous kinetic study of the oxidative dehydrogenation (ODH) reaction of propane on a vanadium oxide-based submicron diameter fiber catalyst has been developed. The proposed kinetic model simulates the conversion- selectivity ...

It is widely accepted that, when an electrokinetic remediation (EKR) is performed for the cleanup of most toxic metals, an enhancement is needed. During the unenhanced EKR the reactions at the electrodes, probably water ...
