Diesel-like Fuel Obtained by Catalytic Pyrolysis of Waste Engine Oil

The aim of this study is to obtain gasoline like fuel from waste engine oil by catalytic pyrolysis which can be used in internal-combustion engines. Petroleum based waste engine oil can be converted into reusable products such as gasoline and diesel fuel. The aims of waste engine oil processing are upgrading via recycling and re-refining processes of the petroleum based wastes by converting them into reusable products such as gasoline and heavy oil. Possible acceptable processes are distillation, cracking and pyrolysis. The pyrolysis liquid products of waste lubricant oil can be used as alternative engine fuel. The yields of liquid products, they were called as "waste oil gasoline" increase increasing temperature and catalyst amount. To investigate the effects of catalysts on the yields of distillation the purified oil samples were blended as mass basis of 2.5%, 5.0%, and 10.0 with catalysts known as perlite and wood ash. The highest yield of liquid product was 92.5% which can be obtained from the pyrolysis with 10% perlite. The yields of liquid products from pyrolysis of waste lubricant oil in the presence of perlite are higher than those of wood ash catalytic runs.
