The Influence of Kerosene to Increase the Quality of Coal from Bayah South Banten Using UBC Methode

Abstract

The increasing price and the decreasing stock of fossil fuel nowadays are two factors
that make the use of alternative fuel with lower price become necessity. The source of
energy that can be used to fill the gap between convensional fossil fuel towards cleaner
and renewable energy is Coal. South Banten has a massive stock of coal, around 70% of
all the mineral sources in South Banten, but the quality of the coal is low, due to the
sulfur content around 2.28 % dry basis and a high water content that lead to the lowest
calor content. The aim of this research is to lowering the sulfur and water content of
the coal. Upgrading Brown Coal methode is the methode used to reach the aim stated.
The research was settle at temperature 150: C, pressure 350 kPa, and addition of
kerosene as the solvent. The result of the research shows the increasing of calor
content and the decreasing sulfur content when the evaporation temperature gradually
increased.
