PENYERAPAN GAS CO HASIL PEMBAKARAN SAMPAH MENGGUNAKAN MODIFIKASI SORBENT CA(OH)2, TANAH DIATOMEAE (DE) DAN KOMPOS DALAM REACTOR FIXED BED

Abstract

This study aims to improve the reactivity of sorbent Ca (OH) 2 by using the land as a source of silica diatomeae and compost as a source of biosorbent. Diatomaceous earth generally contains CaO, SiO2 and Al2O3. The reaction between SiO2 with Ca (OH) 2 to form calcium silicate hydrate (CaO.SiO2.2H2O) which has a high porosity and reactivity. Compost as biosorbent contains bacteria that can convert CO into CO2 gas and CH4. The results showed that the reactivity of sorbent Ca (OH) 2 increased with the addition of DE and compost. The results also showed that the CO gas absorption increases with increasing height and temperature sorbent bed. Highest CO gas absorption obtained on the use of modified sorbent Ca (OH) 2/DE/kompos (3:1:1), temperature 150^oC and sorbent bed height 6 cm from the variable which had been done.
