Utilization of high specific surface area CuO-CeO2 catalyst for high temperature process of hydrogenproduction

Catalysts were prepared by the hard template method, which yields high surface area porous nanocrystaline cerium oxide and high dispersion of CuO phase. It was found that increasing CuO content acts favorable to the ethanol conversion but also causes faster deactivation of catalyst due to sintering and loosing CuO dispersion. Coking was less pronouced with catalyst samples containing higher content of CuO.

Ru-based catalysts for CO selective methanation reaction in H2-reach gases

In this study complete removal of CO from a hydrogen-reach gas was by means of so-called CO-selective methanation (CO-SMET) was elaborated as an alternative to the preferencial oxidation (CO-PROX). It is, however, demonstrated that a catalyst with 5% Ru on Al2O3 is capable to completely remove CO.

Synthesis of ordered nanostructured CuO-CeO2 catalysts by hard template method

Study focuses on the synthesis method of hard template using KIT-6 silica template. Material synthesized was characterized by N2-adsorption and XRD analyses and tested for water-gas-shift (WGS) reaction activity. It showed very high conversions and selectivity (over 99%) in a temperature range 250-450 deg. C

Novel Method for Fast Characterization of High-Surface-Area Electrocatalytic Materials Using a Carbon Fiber Microelectrode

A carbon fiber microelectrode (CFME) was used for characterization of the nanoparticle catalysts as an alternative to the well-established rotating disk electrode (RDE) method. It was found that the novel CFME method yielded comparable results to the RDE method when investigating the adsorption/desorption processes as well the specific activity for reactions such as the oxygen reduction reaction. Its major advantage over the RDE method is a fast sample preparation and rapid measurement.

Industrial requirements for thermodynamics and transport properties.

Data, models, algorithms, systems, applications, process simulations, standards were identified as important themes. An acute need for accurate, reliable, and thermodynamically consistent experimental data was observed, as well as a great need for reliable predictive models, covering a wide range of compositions, temperatures, and pressures and capable of predicting primary and secondary thermodynamic properties. The survey indicates a great variety of systems where further work is needed.
