Purification and Characteristics of Waste Lubricating Oil as Diesel-Like Fuel
Abstract
This study aims to utilize used lubricating oil (OLB) in diesel-like fuel. OLB is processed by distillation method, heating 600 watts for 120 minutes and varying stirring speeds of 0, 300, and 500 rpm. The results of the highest distillation temperature test at 500 rpm stirring and a molecular cracking reaction occurs so that the long chain is easily cracked. The characteristics of LLB obtained are flash point 144 (PMcc,0°C), density 858.3 (kg/m3), viscosity 3,107 (cSt), and calorific value 10,967 (kcal/kg).
