Aplikasi Desain Faktorial 23 pada Kadar CO2 Proses Purifikasi Bio-gas dengan Adsorben Genteng - Zeolite

Abstract

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 CO_2 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.
