Abstract:
In the present work, the specific effect of the presence of three of the impurities most commonly found in glycerol derived from biodiesel manufacturing on the aqueous phase reforming process has been studied. The influence of the concentration of CH3OH (0-5 wt-%), CH3COOH (0-3 wt-%) and KOH (0-2.8 wt-%) on the aqueous phase reforming of a solution of glycerol (30 wt-%) has been evaluated using a three factor-two level design of experiments with statistical analysis of the results. The results show that the presence of the aforementioned impurities has a significant impact on the global glycerol conversion as well as on the liquid phase distribution. Depending on the concentration of the impurities considered in this work, the global glycerol conversion varies from 60.6 to 90.2 %. Alcohols are the major constituents of the liquid product, and their relative amount, expressed as relative chromatographic area varies from 74 to 91 %.
