—The batteries containing materials which are
dangerous for health and safety of environment. In some type of
battery, its application should be replaced when the power get
lost. The waste of used battery should be well manage or even
reused again for other useful purpose to reduce dangerous risk
for heal and environment. The zinc-carbon battery is a type of
battery that can be used only one time, consist of carbon rod as
positive terminal, zinc case as negative terminal, and mixture of
carbon powder, ammonium chloride, and MnO2 as electrolyte.
Hydrogen sulfide (H2S) is impurities found in the biogas and
should be purified before further application as fuel for engine.
Hydrogen Sulfide (H2S) is rising problem for the engine since
will caused acidity to lubricant and corrosive to metal part of the
engine. In this research the carbon powder of electrolyte part of
the used zinc-carbon battery is reused as desulfurizer. Clay is
added as a binder to make possible to create a pellet. It is found
that the carbon powder from used zinc carbon battery is
excellent as desulfurizer by adding clay as binder.
