- aggregation abstract "The main product of biomass fast pyrolysis is a liquid mixture of numerous organic molecules with water that is usually called pyrolysis oil or bio-oil. The research discussed in this paper was meant 1) to validate a new, semi-continuously operated pyrolysis set-up and 2) to investigate the effect of a repeatedly regenerated ZSM-5 based catalyst (eight reaction/regeneration cycles in total) on the yields and compositions of the pyrolysis products in relation to the applied process conditions and on the catalyst itself. The reliability of the set-up has been proven by multiple repetition of non-catalytic and catalytic (in-situ) pyrolysis experiments for pine wood at 500 oC under identical conditions. As a result, the mass balance closures for all experiments varied from 92 to 99 wt.% while the scatter in measured data was always less than 5%. Changes in the performance of the repeatedly regenerated catalyst have been observed via detailed analysis of the bio-oil (GC×GC-FID and GC×GC-TOF-MS, Karl-Fischer), the non-condensable gases (micro-GC) and the carbonaceous solids (elemental analyser, BET surface area). Along the reaction/regeneration sequence, the yield of organics increased, while water, carbonaceous solids and non-condensable gases decreased. Trends in pyrolysis product yields converging to that of non-catalytic levels were observed, which revealed that the influence of the catalyst slowly declined. The main observation was that the catalyst partially loses its activity in terms of the product distribution along the reaction/regeneration sequence, while retaining sufficient activity in producing the target chemical compounds.".
