K-looping Catalytic Pyrolysis of the Original and Pelletized Biomass for In-situ Tar Reduction and Porous Carbons Production

Abstract

This paper studied the K-catalyzed pyrolysis of rice husk (RH) and its pellet (RHP) at a higher temperature (750 oC) for in-situ tar reduction and porous carbon production. The mass ratio of KOH and biomass greatly affected the physicochemical property of biochar. During carbonization with the KOH, the in-situ generated K2CO3 tailored the morphology and size of the self-template SiO2, giving rise to the RH-chars with open foam-like porous architectures enrich in micro- and meso-pores. The KOH activation via the one-step pyrolysis could produce the highly porous carbons (e.g., RH-char 1, RH-char 2, and RHP-char 1) along with high specific surface areas and high contents of oxygen-functionalities that have high potential applications on energy storage and adsorption process.
