Abstract
In this study, leonardite and red clay obtained from Mah Moh mine, which they were
utilized as low cost and eco-friendly adsorbents for hydrogen sulphide (H2S) removal
from biogas. The experiments were performed with a synthetic biogas: 72 % CH4, 28 %
CO2 and 4,400 ppm H2S. The adsorbents were packed in a column of 3.0 cm in diameter.
Geotech GA5000 was used to analyze synthetic biogas, at the continuous fl ow rate of
50 mL/min. The H2S adsorption capacity of leonardite and red clay were 0.2087 and
0.0134 mg/g, respectively. Modifi ed leonardite and red clay were upgraded by sodium
hydroxide (NaOH) (5 - 40 %) and coconut shell biochar (CSB) (15 - 70 %) can provide
higher H2S adsorption capacity than the non-modifi ed sample. From the economic feasibility
calculations, the modifi ed leonardite and red clay can be used as suitable adsorbent for
H2S removal from biogas for community use.
