Abstract

Purifying biogas by removing contaminants and carbon dioxide (CO 2 ) to produce biomethane enhances its energy content, making it suitable as fuel and for injection into natural gas grids. Bamboo-derived adsorbents Bamboo-500 (pyrolyzed at 500 °C), Bamboo-700 (pyrolyzed at 700 °C), and Bamboo-A-900 (activated with CO 2 at 900 °C) were synthesized and characterized to evaluate their performance for CO 2 and CH 4 adsorption. Increasing pyrolysis temperature from 500 °C to 700 °C and further CO 2 activation at 900 °C enhanced adsorption capacities of CO 2 and CH 4 due to improved surface area and micropore structure. In this study, the novel Approximate Adsorption Performance Indicator (AAPI) approach is introduced, offering an efficient method for evaluating adsorbent performance, particularly in biogas upgrading. AAPI results suggest Bamboo-500 is suitable for biogas upgrading at very low pressures (<0.12 MPa) with low regeneration energy and acceptable CO 2 capacity (1.9 ± 0.2 mol kg −1 ). However, Bamboo-A-900 excelled at medium and high pressures by its highest CO 2 adsorption capacity (8.0 ± 0.3 mol kg −1 ) promoted by the high surface area (1220 m 2 g −1 ) and calcium oxide presence. Finally, Bamboo-A-900 shows promise for enhancing CO 2 adsorption and biogas upgrading. Bamboo-derived adsorbents offer a sustainable solution for biogas upgrading, supporting Sustainable Development Goals by promoting clean energy transitions.
