Abstract

The use of alternative fuels is still developing and being researched. One of the alternative fuels is diisopropyl ether which has a high cetane number so that it is good for use as a fuel. Diisopropyl ether can be obtained through the dehydration process of isopropanol. Zeolite has a hollow structure so that it can increase the surface area and has a high ion exchange capacity. Zeolite surface area can occur after the zeolite is activated. In this study, the conversion of isopropanol to diisopropyl ether was carried out using a cobalt phosphate zeolitas a catalyst. . The research begins with activation zeolite was carried out by treating HF 1% and HCl 6 N. Metal modification was carried out by comparing the concentrations of 2,4,6,8,10 mEq/1 g zeolitwith CoCl2.6H2O 0,1 M. Then the catalyst with the best composition was tested for characterization using XRD, SEM-EDS and FT-IR. Zeolite cobalt phosphate catalyst 8 mEq/1 g zeolite is the catalyst with the best composition with the conversion results and the selectivity, namely 66.19% and 46.72% with the resulting yield of 34.99%. This is supported by the acidity analysis which states that the 8 mEq/1 g zeolite cobalt phosphate catalyst has the highest total acidity, which is 1.827 mmol/g. The XRD and SEM-EDS tests showed that the zeolite crystals had been modified by cobalt phosphate metal seen from the presence of 2 theta peak and the results of the compound content in EDS, namely at a diffraction angle of 61.2º with elements containing Co compounds of 2.23% on a zeolite-CoO catalyst and 67.3º with elements containing Co of 1.61% and phosphate of 9.23% on a zeolite-Co(H2PO4)2 catalyst. In the FT-IR characteristics, the Bronsted acid were detected in the wave number of 1641.42 cm-1 and Lewis acid groups detected of 1436.97 cm-1.
