Abstract

One of the zeolite producing areas in Indonesia is Sukabumi. Natural zeolite originating from Sukabumi is composed of three main types of minerals: mordenite, clinoptilolite, and quartz. Zeolite as a catalyst can be improved by carrying out physical and chemical activation processes. Physically the catalyst can be activated by reducing the size of the zeolite through the grinding and sieving method. This physical activation process can increase the surface area of the zeolite. In this study, variations in the size of zeolite 80 mesh and 100 mesh were carried out that chemically activated by the acid activation method through immersion of natural zeolite with HCl and HF from this acid activation process it will increase the acidity of the zeolite. Measurement of functional groups and chemical compounds in activated zeolite using XRF and FTIR. The results of XRF analysis showed that the SiO2 content in 80 mesh zeolite was 69.5% and in 100 mesh zeolite was 82.1% and the FTIR analysis showed the presence of the C-H alkene functional group at a wavelength of 675-995 cm-1, ring C-H aromatic at a wavelength of 690-900 cm-1, C-O alcohol/ether/carboxylic acid/ester at wavelength 1610-1680 cm-1, functional group C=C alkene 1610-1680 cm-1, the O-H functional group is carboxylic acid at a wavelength of 3500-3650 cm-1 and an alcohol monomer/phenol O-H functional group at a wavelength of 3590-3650 cm-1.

Abstract

Zeolite as a catalyst can increase its activity by carrying out physical and chemical activation processes. Physical activation can be activated by reducing the size of the zeolite through grinding and sieving methods, from the physical activation process it can increase the surface area of the zeolite. In this study, zeolite was chemically activated by acid activation method by immersing natural zeolite with HCl and HF. The oxide compound in the activated zeolite was characterized using XRF. The activated zeolite was used to reduce the free fatty acid levels with variations in the addition of 7 to 10 grams of zeolite. The content of free fatty acids is then compared with the quality requirements of cooking oil according to SNI 01-3741-2013. The results of the research conducted showed that there were differences in the content of oxide compounds in zeolite before and before activation with differences in SiO2 content, namely 69.4% before activation and an increase of 82.1% after activation. The results of the state test including physical properties, odor, and taste tests of used cooking oil that have been purified indicate that used cooking oil that has been purified meets the quality requirements of cooking oil based on SNI 01-3741-2013. Used cooking oil that has been purified has a normal taste, does not smell. rancid and yellow. The content of free fatty acids meets the requirements of SNI 01-3741-2013 for all variations of the addition of zeolite with the highest decreasing value obtained at the addition of 10 g of zeolite with a free fatty acid content value of 0.22%.
