As an adsorbent, natural zeolite from the Lombok island Indonesia was used. Zeolite is used for the purpose of purifying biogas produced from the anaerobic digestion (AD) process. To enhance the adsorption capacity, the zeolite underwent activation using distinct strong base and acid solutions—potassium hydroxide (KOH) and hydrochloric acid (HCl)—with concentrations of 10%, 15%, and 20%, individually. The experiment was carried out until the adsorbent reached saturation, at which point the methane (CH4) concentration began to decline. It was revealed that the typical Lombok zeolite showed good performance in increasing the concentration of CH4 in biogas. Furthermore, zeolites work better when activated with strong base solutions and at high concentrations. This is indicated by the achievement of higher CH4 concentrations and a longer saturation time. The results from analyzing zeolite features and pore characteristics indicate that acidic and base compounds yield distinct outcomes in terms of the surface structure of zeolite pores.</p> </p></abstract><publication_date><month>04</month><day>24</day><year>2024</year></publication_date><publisher_item><identifier id_type="pii">gnest_05800</identifier></publisher_item><doi_data><doi>10.30955/gnj.005800</doi><timestamp>1716147816</timestamp><resource>https://journal.gnest.org/publication/gnest_05800</resource></doi_data></journal_article></journal></body></doi_batch> </div>
