Abstract
Bamboo is an abundant plant in many Asian countries and especially in China; it has an extremely rapid growing rate, and it can be considered as a sustainable wood resource. In this paper, a comparative study of pyrolysis of bamboo in the presence of high-temperature steam and an inert atmosphere (N2) as well as characterization of products has been conducted. Evaluation of experimental results showed that faster devolatilization can be achieved in the presence of high-temperature steam. Furthermore, the gas composition indicates interaction of steam with vapors and solid species even at low temperatures. Analysis of the obtained liquid after steam pyrolysis at 797 K revealed that the H/C and O/C ratios in the liquid are 1.54 and 0.16, respectively. The characteristics of the products indicate possible exploitation of derived char as an activated carbon precursor, a reducing agent in metallurgical processes, or a solid fuel for gasification and combustion processes. The composition of the liquid fraction suggests further exploitation as a liquid fuel and/or chemical feedstock.
