Aqueous phase reforming (APR) of waste oxygenates offers the potential for sustainable hydrogen production. However, catalyst stability remains elusive, due to aggressive hydrothermal conditions employed. Herein, we show that catalytic performance and Pt supported on LaAlO 3 catalysts glycerol APR is strongly influenced by purity . Calcination support at 700 °C produces perovskite an amorphous ...

Alternative energy sources, such as various fuel cell technologies, have attracted intense attention due to their high efficiency and low emissions of pollutants. Methanol, with its high hydrogen/carbon ratio, low sulfur content and the absence of carbon–carbon bonds, has been identified as a highly suitable source for onboard production of hydrogen [1]. Among several reactions for converting m...

This work presents a controllability analysis of a low temperature ethanol reformer based on a cobalt catalyst for fuel cell application. The study is based on a nonlinear dynamic model of a reformer which operates in three separate stages: ethanol dehydrogenation to acetaldehyde and hydrogen, acetaldehyde steam reforming, and water gas shift reaction. The controllability analysis is focused on...

Many hydrocarbon reactions of interest involve either poorly characterized reactants and products andor large numbers of simultaneous reactions. An important step in understanding the behavior of such systems is to develop quantitative pictures of the feeds and products and the transformations which connect them. The processes for constructing these reaction visualizations is illustrated by exa...

This article reviews research related to the activation of methane by Ni and Ru using model catalysts, highlighting the surface science work carried out using molecular beams methods and elevated pressure reaction studies. Emphasis is placed on connecting the model studies of surface science with the corresponding results obtained on the analogous ‘real world’ catalysts. These combined studies ...

The biogas needs to be reformed before electro-chemical conversion in the solid-oxide fuel cell, which can promoted efficiently with wise thermal management and reforming conditions. To ensure system safety catalysts durability, additional mineral-bearing water carbon deposition should avoided. This paper conducted a detailed biogas-SOFC CHP analysis considering four layouts, featuring hot cold...

Designing a simple, yet representative reaction network for subsequent micro-kinetic analysis is important limiting the cost of evaluation and ensuring model solvability. This currently achieved by employing sensitivity over comprehensive (CRN) to screen species. However, as being simplified particular catalyst composition, it loses its transferability other compositions. Therefore, in this stu...
