Penggunaan NaOH Sebagai Leaching Agent Dan Pengaruh Penambahan H2O2 Pada Desulfurisasi Petroleum Coke
Abstract: A study on the use
of NaOH as the leaching agent and the effect of adding H2O2 in desulfurization
of petroleum coke. This study aimed to observe the effect of concentration and
stirring time on the desulfurization of petroleum coke using NaOH as the
leaching agent, and determine the effectiveness of the use of NaOH as a
leaching agent in optimum condition in the desulfurization of petroleum coke
and see the effect of the addition of H2O2 by leaching method using NaOH.
Research on separation of sulfur petroleum coke leaching method performed on
samples derived from petroleum coke PT.Pertamina UP II Dumai 0440% sulfur
content. To determine the sulfur content in petroleum coke after leaching were
analyzed using X-Ray Flouroscence (XRF). In this separation studied the
influence of the concentration of NaOH as the leaching agent and the effect of
stirring time on levels of sulfur that can be separated. The results showed
that the concentrations of NaOH and optimum stirring time, which can be
separated sulfur content is 26%. This research also studied the effect of
adding H2O2at the optimum conditions. The results showed 1.5% H2O2
concentration can separate the sulfur in petroleum coke amounted to 1.82%. From
the research it can be concluded that the influence of the concentration and
time of agitation increases levels of sulfur extracted until a certain optimum
value of 75% and 60 min, while the addition of high concentrations of H2O2 less
effective. The addition of 1.5% H2O2can significantly reduce levels of sulfur
are extracted at the 90% confidence level.
