Recycling Waste Lubricants with Different Types of Base Oil into Low Sulfur Fuel with Two Stage Distillation Pyrolysis Process

Abstract

Abstract The intent and purpose of the research is to improve fuel performance by recycling waste lubricants into low sulfur fuel, using waste lubricants made of various types, namely mineral, semi-synthetic, full synthetic, and mixtures from different sampling sites, with the scope of lubricant waste coming from motorcycles. Recycling waste lubricants is chosen in 2 stages, to get purer fuel and better fuel performance, it is called a distillation pyrolysis process. The advantage of using this distillation pyrolysis process is that it does not use high temperatures, and is cheap and fast. Waste lubricant recycling using a two-stage distillation pyrolysis process produces a fuel with a sulfur content that decreases by 61.98 %wt -68.61%wt in stage I and 66.32 %wt - 70.66 %wt in stage II for waste lubricants with four different base oil. Thus, proving that the two-stage distillation pyrolysis process can reduce sulfur content and can also improve fuel performance at the characteristic values of several other chemical properties.
