Abstract


ABSTRACT

The small amount of oil reserves in Indonesia currently causes the need for fuel oil to increase, so alternative fuels are needed. The oil produced from polypropylene pyrolysis is a type of processed polypropylene plastic waste through the pyrolysis process. This oil can be turned into alternative fuels because it produces less residue and more liquid products but with lighter carbon chains. This study aims to determine a combustion characteristic using an experimental method of single droplet combustion of fuel oil resulting from the pyrolysis of pure polypropylene with a mixture of graphene nanocarbon with variations of 1 PPM and 5 PPM. The results of the study showed that the highest flame height and width were found in the combustion of the oil produced from polypropylene pyrolysis of 5 PPM variations with a height of 25,033 mm and a width of 10,255 mm due to one of the phenomena that occurred, namely microexplosion. A low burning rate indicates better combustion and is indicated by the 5 PPM variation burning rate value which is 0.82 mm. The fuel oil produced from the polypropylene pyrolysis with the variation of 5 PPM has better combustion characteristics due to the nature of graphene nanocarbon which when added to the fuel will make the fuel molecule bonds more reactive and easier to decompose so that it is more volatile and reacts quickly.

 

Keywords: droplet, pyrolysis, polypropylene, and graphene nanocarbon
