In this study, the production of bio-oil and activated carbon from sugarcane bagasse and molasses was
investigated via pyrolysis and CO2activation. The pyrolysis process yielded char, bio-oil, and gases in
25.90, 41.11, and 32.99 wt%, respectively. The properties and characteristics of obtained bio-oil are
comparable with the proposed specifications of the various grades of pyrolysis oils and couldfind potential application as fuel or source of a number of valuable chemicals. The activation process with CO2
showed it was possible to obtain activated carbon with surface area up to 900 m

over 4.5 h activation time with a predominance of micro- and mesopores. The bagasse-based activated carbon was
found to be efficient in comparison to commercial activated carbon in removing molasses color, and
might provide a lower-cost alternative adsorbent for use in sugar decolorization in raw sugar refining
