Abstract:
In the present work, the influence of the glycerol concentration (10 wt-% to 30 wt-%) at 50 bar and 240 ºC, on the aqueous phase reforming process, in terms of global glycerol conversion, gas and liquid yields and composition of the liquid phase obtained during the reforming reaction over time has been studied. The experiments were carried out in a stainless steel fixed-bed tubular reactor for 4 h. A NiAlLa catalyst was selected for the present work. It was prepared by coprecipitation, having a 28% (relative atomic percentage) of Ni expressed as Ni/(Ni+Al+La), and an atomic La/Al molar ratio of 0.035. A W/mglycerol ratio of 10 g of catalyst min/ g of glycerol was used in the experiments. From the results it was found that the glycerol concentration had a statistically significant influence on the global glycerol conversion, the gas and liquid yields, the liquid product distribution as well as on the evolution of all these variables over time.
