Biodiesel fuel from waste cooking oil using zeolite catalyst

Abstract

The waste of household cooking oil is thrown away so that it causes environmental problems. Therefore, this problem must be responded to immediately, for example by processing household waste cooking oil into environmentally friendly biodiesel as an alternative method to address this problem. This household cooking oil waste treatment aims at reducing environmental problems, furthermore to discover a way for the waste of household cooking oil to be processed as an alternative fuel to replace diesel, which is biodiesel as a renewable energy source. This study aims to make biodiesel from household waste cooking oil to eliminate or reduce levels of free fatty acids (ALB) contained in used cooking oil catalyst, namely Zeolite Bayah catalyst, while the temperature and reaction time is a fixed variable esterification reaction. The results of this study indicate that the processing of used cooking oil using Zeolite Bayah catalyst can reduce the free fatty acid content contained in used cooking oil, and the physical characteristics of biodiesel generally meets the SNI-04-7182-2012 standard. So that it can be seen that the Zeolite Bayah catalyst influenced the process of reducing free fatty acids in used cooking oil, it can be concluded that some of the parameters are already included in the national standard 04-7182-2012, and it can be seen that the Zeolite Bayah catalyst density parameters obtained the results of 871, the density of NaOH catalysts obtained 862, while from the national standard 04-7182-2012, it was set at 850-890. Both of these results have met the standard for the quality of making biodiesel.
