Abstract:

Fast pyrolysis is one of the techniques considered for the production of so called “second generation” biofuels and green chemicals. The produced “bio­oil” is just an intermediate which needs subsequent treatment like fractionation and/or isolation in combination with catalytic upgrading to the desired final products. The objective of this research is to investigate possible beneficial effects on the bio­oil quality of various catalysts applied inside the pyrolysis reactor in relationship with the applied process conditions. First experiments have been carried out in a fully controlled continuous mini­plant designed and constructed by BTG Biomass Technology Group BV on basis of auger reactor technology for (catalytic) biomass fast pyrolysis. The catalyst samples were provided by Albemarle Catalyst Company BV. The experimental reproducibility has been checked by repetition of several non­catalytic experiments under identical conditions. Of these tests the average yields on as received basis are 67.3, 14.7, and 18 wt % for bio­oil, gas, and char, respectively. Experiments were performed at a fixed pyrolysis temperature of 500 °C and pine wood was selected as feedstock. Two different catalysts were also tested with an acceptable mass balance closure. Some physical properties, such as; water content, pH and TAN of liquid product and degree of devolatilization of feed were analyzed. Elemental analyses of virgin bio­oil and water phases of catalytic bio­oils were carried out. Catalyst impact on the yield distribution and product properties was observed. In this paper some preliminary results are presented.
