Fast pyrolysis of biomass for bio-oils

Abstract

This paper gives a proper overview on various possibilities for power generation from biomass in small-scale. One should note that the concept power generation from biomass in the article refers straight to combined heat and power (CHP) production based on biomass. Fast pyrolysis of hazelnut cupula was also investigated experimentally in a fixed-bed reactor under various conditions. The fixed-bed fast pyrolysis experiments have been conducted on a sample of hazelnut cupula in a fixed-bed reactor to determine particularly the effects of pyrolysis temperature, and ZnO catalyst on the pyrolysis product yields and the quality of liquid products. The reactor was heated at a heating rate of 200 oC per minute to a pyrolysis temperature of 400, 500, 600 and 700 oC. Experiments show that the maximum oil yields of 52.5% and 57.6% were obtained without and with catalyst at 600 oC, respectively. An increased of 5.0 percent was achieved when compared without catalyst.
