Peningkatan Kualitas Bahan Bakar Biogas Melalui Proses Pemurnian Dengan Zeolit Alam
Abstract: Biogas from digester
consists primarily of methan (CH4) and carbondioxyde (CO2).
Tracecomponents that are
often present in biogas
are water vapor
(H2O), hydrogen sulfide(H2S), hydrocarbons (HC),
ammonia (NH3, oxygen (O2), carbon monoxide (CO) and
nitrogen (N2). In order to improve the quality of biogas, a cleaning
process to remove the trace components and an
upgrading process to
adjust the calorific
value are needed.
A number of
techniques have been developed
to remove the
trace components from
biogas. In this
experiment, however,chemical
absorption of CO2 and H2S by
solid zeolite in
a plastic bag
was experimentally
investigated. The solid
zeolite was activated
by heat treatment
and KOH. Absorption
characteristics were examined. Test results revealed that the solid zeolite
used were effective in adsorbed CO2 and H2S in biogas,
creating CH4 enriched fuel. Absorption capability was transient
in nature. With
regular replacement or
regeneration of used
solid zeolite, upgraded biogas
can be maintained. This technique proved to be promising in upgrading biogas quality.
