A nickel/spinel (Ni/MgAl_2O_4) catalyst, w(Ni) = 22 wt %, was investigated in situ during reduction with wide-angle X-ray scattering (WAXS) in a laboratory setup and with anomalous small-angle X-ray scattering (ASAXS) at a synchrotron source. Complem

Second generation biorefineries transform lignocellulosic biomass into chemicals with higher added value following a conversion mechanism that consists of:pretreatment, enzymatic hydrolysis, fermentation and purification. The objective of this study

Combustion and Flame
The sulfation of KCl during biomass combustion has implications for operation and emissions: it reduces the rates of deposition and corrosion, it increases the formation of aerosols, and it leads to higher concentrations of HCl and lower concentratio

Combined in situ small- and wide-angle X-ray scattering (SAXS/WAXS) studies were performed in a new laboratory setup to investigate the dynamical properties of a ruthenium/spinel (Ru/MgAl2O4) catalyst, w(Ru) = 4 wt %, during the reduction and subsequ

Methane steam reforming is the key reaction to produce synthesis gas and hydrogen at the industrial scale. Here the kinetics of methane steam reforming over a rhodium-based catalyst is investigated in the temperature range 500–800 °C and as a func

The kinetics of methane steam reforming over a Ru/ZrO 2 catalyst was studied at 1.3 bar total pressure and in the temperature range 425–575 °C. These data were fitted by combining a reactor model with a series of kinetic models. The best fit was o
