Preparation and Characteristics of Effective Biochar Derived from Sugarcane Bagasse as Adsorbent

Abstract

Biochar is an efficient and economical adsorbent. Raw materials for biochar from biomass are abundantly available. This study aims to modify biochar from sugarcane bagasse using biochar HCl from the pyrolysis process with time variations from 300°C to 600°C. HCl mixture has a concentration of 3M. The research results show that pyrolysis operating temperature can affect biochar yield, structure, and energy distribution. The highest product of biochar was obtained at 300°C at 34.34%. The morphological structure of biochar at 300°C has holes with reasonably small sizes. However, at 400°C, pore size biochar increases from 9.90 nm to 18.42 nm at 600°C. The carbon content in biochar increases with the pyrolysis temperature. The highest carbon content was obtained at 89.91%. The structural properties of biochar have been discussed in this study in the form of pore volume, BET surface area, and pore radius. This research has shown that pyrolysis temperature can affect the condition of biochar.
