摘要：

The combination of pyrolysis and CO2 gasification was studied to synergistically improve the syngas yield and biochar quality. The subsequent 60-min CO2 gasification at 800 degrees C after pyrolysis increased the syngas yield from 23.4% to 40.7% while decreasing the yields of biochar and bio-oil from 27.3% to 17.1% and from 49.3% to 42.2%, respectively. The BET area of the biochar obtained by the subsequent 60-min CO2 gasification at 800 degrees C was 384.5 m(2)/g, compared to 6.8 m(2)/g for the biochar obtained by the 60min pyrolysis at 800 degrees C, and 1.4 m(2)/g for the raw biomass. The biochar obtained above 500 degrees C was virtually amorphous. (C) 2017 Energy Institute. Published by Elsevier Ltd. All rights reserved.
