Abstract

Carbon capture and storage (CCS) in bioenergy sector aims to neutralise the carbon footprints to generate green energy. Biochar is one of the major waste-products in bioenergy sector which holds the capability to capture carbon from the environment. Biochar has many other useful applications, such as, it is used as a soil nutrient enhancer, containment sorbent, carbon sequester, catalyst and energy storage material. The performance of biochar is dependent mainly on two factors: the porosity and surface area. Biochar produced from different raw materials exhibit different measurements of surface area and porosity. This research will focus on the biochar derived from plant-based biomass.
Biochar: The biochar samples under investigation are derived from the plant-based biomass, hence contains cellulose, lignin and hemicellulose as main components. Hemicellulose decomposes within 220-315°C, cellulose being highly stable decomposes within 315-400°C, and lignin due to its complex structure decomposes within 150-900°C. Lignin is one of the main contributors to the surface area and porosity in the biochar (Leng et al. 2021).
Surface area and porosity measurements: Measurements of surface area and porosity of biochar is a major challenge. Biochar usually contains high moisture content, usually around 40%. It has been observed that drying of biochar samples before BET analysis alter the delicate structure of micro- and meso-pores, hence affects the accurate measurements of these quantities (Maziarka et al. 2021). Alternative methods, such as, cyclohexane vapour sorption analysis measures the surface area and porosity reliably without disturbing the delicate micro- and meso-pore structure of biochar samples. This research compares the measurements of the surface area and porosity of biochar samples analysed through BET technique using Nitrogen gas as an adsorbent and cyclohexane vapour sorption method to determine pore size and surface area for better understanding of suitability of measurement techniques.
