Abstract
Recycling and rerefining are the applicable processes for upgrading of petroleum-based wastes by converting them into reusable products such as gasoline, diesel fuel, and heavy oil. Possible acceptable processes are cracking and pyrolysis. The aim of the study was to obtain diesel fuel from waste lubricating oil by pyrolitic distillation method, which can be used in diesel engines. If the purpose were to maximize the yield of distillate products resulting from crude oil pyrolysis, a low temperature, high heating rate, and short gas residence time process would be required. The effect of sodium carbonate (Na2CO3) as an additive on density, viscosity, flash point, sulfur content, higher heating value, and pyrolytic distillation yields was investigated. The purified oil samples are blended separately with additives having mass basis of 2%, 6%, and 10%. The mixed samples were exposed to pyrolytic distillation process to produce fuels to be used in engines.
