BIOFUEL PRODUCTION FROM THE
TORREFACTION OF UNFRIENDLY
BIOWASTES USING CARBON DIOXIDE AS

U
nfriendly biowaste (sweet potato vine, oil camellia shell and building
demolition wood) will have adverse effects and harms on agricultural land
and the environment, and it is not suitable for direct disposal and reuse on-
site. The torrefaction procedures of cracking furnace and plasmatron reactor
used in this study are advanced heat treatment technology. The gas, liquid
and solid products can be achieved effectively from the thermal-treatment
of unfriendly biowastes using carbon dioxide as upgraded agent at the high-
temperature reactors. The operational parameters include furnace types,
temperature, carrier gas, CO
2
concentration, batch and semi-batch feeding
of samples etc. The samples from the pre-treatment, products of liquid, gas
and solid from the experiment were all processed under the characteristic
analyses, including approximately analysis, heating values, GC-MS, GC-
TCD, EA, FTIR, TGA etc. The thermal effect of CO
2
in the exhaust gas on the
torrefaction of the biowastes proved that CO
2
activation can accelerate and
improve the calcination reaction. The main reaction mechanisms are water
shift reaction and Boudouard reaction; it should be due to that the gaseous
CO
2
reacted with H
2
and carbon, respectively, while resulting in the conversion
from CO
2
to CO. This study confirmed that unfriendly biowaste not only can
be converted into solid fuels completely but also a large syngas is produced.
This technology shows a great future potential development.
