The aim of this work is to study the tars conversion in conditions representative of biomass gasification in a fluidized bed reactor. Experiments are conducted at 850°C and atmospheric pressure in a fluidized bed reactor with toluene as tar model. Influences of the nature of the media (sand and olivine) and of the reactive atmosphere (steam and hydrogen partial pressures) on toluene conversion are...
We report herein the synthesis of an organic-inorganic hybrid composed by the ionic liquid protected Keggin structure, as a precursor for acid catalyst and its subsequent application in the methanol dehydration reaction. Special attention was paid to the thermal stability of the resulted hybrids as a function of the Keggin anion. The catalytic behaviour of these new materials are also studied and...
Zeolites having different pore topologies were tested in the dehydration of methanol into dimethylether (DME) under inert and oxidative atmosphere. The experiments were carried out under air to inhibit the Methanol-To-Hydrocarbons (MTH) reaction, which tends to decrease the selectivity in DME. In addition, the presence of air led to broadening the operational temperature range (OTR) up to 400°C, while...
