Abstract

Biogas merupakan salah satu fokus pemerintah dalam upaya pengembangan energi baru terbarukan berbasis bioenergi. Biogas ditargetkan dapat berkontribusi dalam bauran energi nasional sebesar 489,8 juta m3. Namun, realisasinya pada bulan September 2022 hanya sebesar 32,47 juta m3.Keberadaan CO2 sebagai impuritas dengan konsentrasi terbesar mengakibatkan penurunan nilai kalor pembakaran biogas. Oleh karena itu, perlu dilakukan permurnian untuk meningkatkan nilai kalor pembakaran. Salah satu cara untuk memurnikan biogas yaitu adsorpsi dengan menggunakan adsorben karbon aktif. Peningkatan kemampuan karbon dapat dilakukan dengan modifikasi karbon aktif dengan impregnasi senyawa amina. Pada penelitian ini, karbon tempurung kelapa aktif diimpregnasi MEA dengan variasi rasio massa Karbon Aktif/MEA 1:1; 1:1,25; 1:1,5; 1:1,75; 1:2. Hasil penelitian ini didapatkan peningkatan breakthrough time pada karbon aktif terimpregnasi sebesar 2,6 kali jika dibandingkan dengan karbon aktif. Kapasitas adsorpsi tertinggi diperoleh dengan rasio Karbon Aktif/MEA 1:2 dengan nilai kapasitas adsorpsi sebesar 129,178 mg CO₂/gr adsorben.

English Abstract

Biogas is one of Indonesian Government’s focuses on renewable energy development in Indonesia based on bioenergy. The goal for biogas Biogas’s contribution in national energy usage in 2025 is 489,8 millions m3. However, the realization as of September 2022 is only 32,47 millions m3. Biogas consist CO2 as an impurity substance with highest concentration that causes a decrease in calorific value of biogas combustion. Therefore, it is necessary to carry out purification to increase the calorific value of combustion. One way to purify biogas is using adsorption process with activated carbon adsorbent. The capacity of activated carbon can be increased by adding amine compound with impregnation method. The aims of this research are to determine the effects of MEA (Monoethanolamine) impregnation towards the capability of activated carbon in CO2 contained in biogas using adsorption column and to determine the effects of mass ratio of activated carbon with MEA (Monoethanolamine) solution in impregnation process towards adsorption capacity of CO2. In this research, mass ratio variations of Activated Carbon/MEA used in impregnation process are 1:1; 1:1.25; 1:1.5; 1:1.75; 1:2. The results of this research showed that the breakthrough time for impregnated activated carbon increased by 2.6 times compared to activated carbon. The highest adsorption capacity was obtained with an Active Carbon/MEA ratio of 1:2 with an adsorption capacity value of 129.178 mg CO₂/g adsorbent.
