A long term pilot scale experiment with steam reforming treatment technology was conducted for volume and weight reduction of uranium contaminated waste tri-n-butyl phosphate/n-dodecane solvent (TBP/dodecane) which was difficult to incinerate. The technology consists of a steam reforming process and a submerged combustion process. In the first process, TBP/dodecane is vaporized and pyrolyzed wi...

Glycerol is the main byproduct of biodiesel production and its increased production volume derives from the increasing demand for biofuels. The conversion of glycerol to hydrogen-rich mixtures presents an attractive route towards sustainable biodiesel production. Here we explored the use of Pt/Al(2)O(3)-based catalysts for the catalytic steam reforming of glycerol, evidencing the influence of L...

The catalytic combustion of methane/air mixtures is investigated experimentally and numerically at gas turbine relevant conditions (inlet temperatures up to 873 K, pressures up to 15 bar and spatial velocities up to 3 × 106 h−1). Experiments are performed in a sub-scale test rig, consisting of a metallic honeycomb structure with alternately coated (Pd-based catalyst) channels. Simulations are c...

This paper reports on the design of novel reactor for low-temperature growth of Vertically Aligned Carbon Nanotubes (VACNTs). Two mechanisms for selective heating catalytic nanoparticles were investigated: (i) a heating from exothermic reaction of catalytic oxidation and (ii) an induction heating. The requirements for efficient induction heating catalytic particles of size varying from micron t...

Two novel routes for the production of gasoline from pyrolysis oil (from timber pine) and biogas (from ley grass) are simulated, followed by a cradle-to-gate life-cycle assessment of the two production routes. The main aim of this work is to conduct a holistic evaluation of the proposed routes and benchmark them against the conventional route of producing gasoline from natural gas. A previously...

Mo2O5 2+-ZSM-5 (Mo/Alf = 0.4, Si/Alf = 20) samples prepared by sublimation of MoO3 were carburized in CH4 to form MoCx clusters active in CH4 pyrolysis and then exposed to different CO2/CH4 mixtures. CO2/CH4 reactant ratios between 0 and 0.1 increased catalyst stability but decreased pyrolysis rates, and ratios above 0.1 led to a sudden loss of activity that was reversed after removal of CO2. B...

Visualizing and measuring the gas distribution in close proximity to a working catalyst is crucial for understanding how the catalytic activity depends on the structure of the catalyst. However, existing methods are not able to fully determine the gas distribution during a catalytic process. Here we report on how the distribution of a gas during a catalytic reaction can be imaged in situ with h...

Introduction A lot of research has been done in catalytic reforming of methane with carbon dioxide. However, the major drawback of the reaction is the cost of the process which requires temperatures between 800 and 1000°C. In these fields, significant advantages are currently expected from non traditional approaches to catalysis. One of these new approaches consists to perform the chemical acti...
