This work describes for the first time the room-temperature synthesis of a high surface area Ni0.7Zn0.3O solid solution by sacrificial template accelerated hydrolysis. The synthesis employs a highly polar ZnO template supported on the surface of a stainless steel wire mesh (SSWM) that allows the material to be produced in a monolithic configuration. The resulting material has a large surface ar...

A detailed model is presented for the analysis of temperature, species concentration, and current density profiles as well as the efficiency and power density of a planar solid oxide fuel cell at direct internal reforming condition. The model describes the interactions of mass transport, heat transport, heterogeneous chemistry, and electrochemistry. The heterogeneous chemistry model for the cat...

Starting with a classical process for producing methanol using the reforming and synthesis steps, a combined approach applying simulation models and a new synthesis strategy, named Effect Modelling and Optimisation (EMO), has been used to optimise the energy efficiency of the process. The method allows to identify different ways of improving the energy efficiency of the process. The modificatio...

Structure-activity relationships of a nanostructured Cu/ZrO2 catalyst for the steam reforming of methanol (MSR) were investigated under reaction conditions by in situ X-ray absorption spectroscopy (XAS) and X-ray diffraction (XRD) combined with on-line mass spectrometry (MS). Temperature programmed activation by reduction in hydrogen or by reduction in a mixture of methanol and water (feed) was...

Abstract Steam reforming of toluene (SRT) has been studied initially in eight nickel-based catalysts where nickel (10 wt%) was incorporated different supports (olivine, Al2O3, MgO, LDH, ZrO2, CeO2 and natural sepiolite) by the incipient wetness impregnation method. Among them, catalyst based on sepiolite exhibited a promising catalytic performance, with high conversion (16%), selectivity to hyd...

Dry reforming of methane for the production of hydrogen and syngas has attracted much attention from both industrial and environmental aspects. The major problem encountered in the application of this process is the rapid deactivation of the catalyst, which is mainly due to coke accumulation and sintering of the catalyst. As an alternative to reduce the coke formation, the combination of CO2 re...

The reforming of pure ethanol was studied over a bi-metallic precious metal (Rh/Pt) catalyst deposited on a ceramic monolith in order to analyze reforming process conditions. High ethanol conversion tests performed at low space velocities (<20,000 h ) confirmed that the catalyst could achieve 100% ethanol conversion to equilibrium concentrations of H2, CO, CO2 and CH4. Low conversion tests at h...

The CO2 reforming of coke oven gases (COG) was carried out over a Ni/γAl2O3 catalyst in order to obtain a suitable syngas for methanol synthesis. The influence of different operating conditions, such as temperature and volumetric hourly space velocity (VHSV), was studied. It was found that the H2 present in the feed gas promotes the Reverse Water Gas Shift reaction (RWGS), which produces water....
