Purpose: of this paper is to investigate the reusability of contaminated waste lubricant oil as flammable fuel by thermal and catalytic cracking process followed by distillation. It also includes the study of using Zeolite and Nickel nano particles as catalyst and its influence catalytic cracking. Design/methodology/approach: A conventional sterilization technique called Autoclaving method, uses high-pressure steam to separate water and other solid waste from the lube oil. It is followed by thermal cracking which breaks the molecular chains and decompose the waste lube oil. The autoclaving process works by the concept that the boiling point of water (or steam) increases when it is under pressure. Findings: Now a days, Industrial and Automobile waste lubricating oils are giving big threat ecology while burning and disposing on bare land. Furthermore, they discharged into the open environment which might make destructive sicknesses to ecology. In water, oil is a visible pollutant, floating as a scum on the surface. Moreover, there is a gradual rise in fuel requirement across the globe, and the consumption of oil assets have driven the researchers to find elective power for internal combustion engines. By the way, diminishing of fossil sources, growing of demand and cost of petroleum based fuels and its environmental hazards as a result of burning or disposing on land have encouraged to investigate possibility of recycling of waste engine oil. Research limitations/implications: A series of process such as filtration, cracking followed by distillation needs expensive experimental setup and regular maintenance as the extracted flammable oil fuel possess significant range of dynamic viscosity values. As all real fluids has its own viscosity, in near future, an investigation is about to do on its behaviour on blending with other flammable fluids. Practical implications: Although the result of this investigation conforming its flammable characteristic of the extracted fuel, the quantity of pollutant free flammable fuel from waste contaminated lube oil being extracted is significant, the cost of catalyst is considerably more, as it plays the most vital part in cracking. This effort likely also reduces foreign exchange, reduces greenhouse emissions and enhances regional development especially in developing countries. Originality/value: The novelty of the work is to prepare pollutant free flammable fuel from waste Lube oil by catalytic cracking process. Here Zoelite and Nickel nanoparticles are used as catalyst which breaks the long-chain molecules of the high boiling hydrocarbon liquids into much shorter molecules.
