“…Another study for carbon capture (CO 2 uptake) suggests the use of bio-fixation for carbon storage by micro-organisms in a tubular photo-bioreactor [26]. Studies have shown that adsorbents of amine-based are problematic in CO 2 capture due to their high energy requirement in their regeneration, corrosive nature, and the degradation of amines themselves [27]. Therefore, selecting the appropriate process for CO 2 and other GHGs is chosen by adsorption and diffusion activity as well as a surface affinity for CO 2 capture.…”

“…where slope = 1/k 2 q e 2 , and k 2 = pseudo 2nd-order rate constant. Concerning Equation ( 8) [27,28] a pseudo-2nd-order kinetic model is said to be applied if we plot t/q t against time (t), resulting in a square with an intercept of 1/q e and 1/h. The same mathematical procedure was utilized for the molded Bentonite adsorbent as shown in Figure 5.…”

This paper introduced the use of two new adsorbents, Akrosorb soda-lime and Bentonite clay, for refinery flare flue gas capture and storage. This study also developed a novel pilot plant model with 409.7149 kg/h capacity refinery flare emission capture with a novel adsorption column configuration using Akrosorb soda-lime and Bentonite clay adsorbents. The flare flue gas adsorption unit was designed, fabricated, test run, and commissioned. The adsorption column temperature is 28 ± 10 °C and has a pressure of 131.7 kPa. The novel plant RSM optimization result shows that 93.24% of CO2 and 62.18% of CO were absorbed, while 86.14% of NOx and 55.87% of HC were absorbed. The established optimum conditions of CO2, NOx, HC, and CO removal efficiency are 22 °C, 2 atm, and 60 min. The variation in flare gas emission could impact the removal efficiency of the plant. The results show the maximum adsorption ability or capacity of 314.30 mg/g, and 68.90 mg/g was reached at 60 min for Akrosorb soda-lime and molded Bentonite adsorbents. Therefore, the developed novel technology for CO2 and other GHG capture is technically feasible and friendly. The combined usage of both adsorbents will enhance the capture of GHG at a low cost compared to using Akrosorb alone as an adsorbent.

“…Salah satu bahan adsorbent yang sering dipakai adalah zeolit yang merupakan mineral kristal alumina silikat berpori terhidrat yang mempunyai struktur kerangka tiga dimensi terbentuk dari tetrahedral [SiO 4 ]4-dan [AlO 4 ]5-. Abdullahi, et.al [4] menyatakan dalam penelitiannya bahwa pada struktur senyawa zeolit, tiap atom Al bersifat negatif dan akan dinetralkan oleh ikatan dengan kation yang saling mempengaruhi dalam proses adsorpsi dan sifat-sifat thermal zeolit. serta zeolit memiliki kemampuan untuk menyerap kandungan gas CO 2 , H 2 S, dan H 2 O dalam biogas karena zeolit memiliki pori-pori berukuran molekuler sehingga mampu memisahkan atau menyaring molekul dengan ukuran tertentu.…”

“…Banyak penelitian untuk menurunkan kadar CO 2 diantaranya Abdullahi, et.al [4], Gibson, J.A.A, et.al [5], Paolini, V., et.al [6], Dienullah, et.al [7], mereka menggunakan bahan zeolite sebagai adsorbent. Dalam penelitianya mereka menyimpulkan bahwa penggunaan adsorben zeolite sangat efektif menurunkan kadar CO 2 dikarenakan ketika biogas terikat pada suatu padatan dan membentuk suatu lapisan film pada permukaan padatan tersebut.…”

The CO2 content in biogas is an impurity, so it needs to be reduced. One way to reduce the levels of CO2 in biogas is by purification with tile-zeolite adsorbents. The purpose of this study was to determine the use of tile - zeolite as an adsorbent in the purification process to reduce CO2 levels using a 23 factorial design. The use of tile powder adsorbents (25% and 75%) - Zeolite (75% and 25%), biogas flow rates of 1 and 6 liters/minute, which were investigated at intervals of 5 and 20 minutes, to collect CO2 content data. Gas Chromatography-Mass Spectrometry (GCMS) is used to test the adsorption gas content. The results are shown by the Pareto curve resulting from biogas purification of CO2 levels, each of which has a magnitude of response to CO2 levels. Increased levels of tile-zeolite as an adsorbent and the rate of biogas flow in the purification process had an effect of reducing CO2 levels by 44.214%. Conversely, an increase in tile-zeolite levels as an adsorbent increases CO2 levels in the biogas purification process. Natural tile is a porous material that can adsorb and has ions that can be exchanged with ions from the outside.
