The Effect of the Catalyst (NaOH) on the Processing of Waste Used Oil Into Liquid Fuel

Abstract

The use of lubricating oil is increasing every year the resulting waste is also increase. Based on the waste criteria issued by the Ministry of Environment, used oil is included in the category of B3 waste. Although used oil can still be used, if not managed properly, it can be dangerous for the environment. The result of this is higher energy prices and decreased oil supply. The process in this research is to treat the used oil waste with heat treatment methods and compare the results and the process of treating used oil waste using a catalyst and without using a catalyst. Then the sample results were tested and compared with existing fuel standards. The catalyst has been shown to affect the process and the resulting results in the used oil processing process. It can be seen in the discussion of the process using a catalyst to produce oil products faster than from the process without using a catalyst, and also the product produced in the process using a catalyst is more and of better quality than the product produced without using a catalyst. There it proves that the function of the catalyst works well, namely as an accelerator of the reaction rate and increasing the desired reaction results.
