| Summary: | Waste sunflower oil (WSO) can be easily produced as a reliable resource sustainable for multifunctional applications. WSO methanolysis in the presence of high silica zeolite beta (HSZB) treated with KOH as a catalyzer in a trans-esterification reaction was used for the fatty acid methyl ester (FAME) synthesis. Tetrahydrofuran (THF) as a co-solvent of 20 wt.% was added for mass transfer intensification. Conversion efficiency of 96.5% was obtained within 4 h reaction time of the reflux reaction, methanol:oil ratio of 9:1, 2 wt.% of catalyst and agitation speed of 300 rpm. Furthermore, these KOH treated HSZB catalysts still exhibit acceptable sustainability and appropriate catalysis in the trans-esterification after three consecutive cycling. It is concluded that K2O existing in the pores and the defect sites of the alkali-treated HSZB can be supplied to the surface of the catalysts structure during the trans-esterification in three consecutive rounds to result in 66.3% percentage of conversion. |
