Abstract:
The pyrolysis of pinewood sawdust in continuous mode and in-line catalytic steam reforming of volatiles have been carried out in a conical spouted bed reactor and fluidized bed reactor, respectively. The influence of temperature (in the 550-700 ºC range), space-time (between 0.03-0.42 gcatalyst h gbiomass -1) and steam/biomass mass ratio (between 2 and 5) on the conversion, distribution of products and their composition has been studied. In order to convert the bio-oil into hydrogen, a commercial Ni reforming catalyst has been used in the second step. The temperature has a positive effect on conversion when it is increased from 550 to 600 ºC, although above 600 ºC the influence is not significant. An increase in the space-time from 0.03 to 0.42 gcatalyst h gbiomass -1 has a positive effect on conversion and H2 yield, while lower CH4 and light HCs yields are obtained. The same trend has been seen when steam/biomass mass ratio is increased from 2 to 5, obtaining higher H2 and CO2 yields and lower CO, CH4 and light HCs yields. The catalyst activity decreases with time on stream, due to the coke deposition in the catalyst surface.
