Abstract:

The excess of glycerol production as a biodieselin side product has pushed researchers to search for new products to evaluate glycerol. In this study, bio-processed glycerol was used as a carbon trigger for heterogenous solid acid catalyst synthesis through carbonization and sulphonation in a single step. The produced catalyst has been used to catalyze the esterization reaction of butanol with levulinic acid to synthesize the fuel biodegradable substance butyl levulinat. The catalyst characterization is made using FTIR, TGA and XRD devices. To determine the catalyst activity of the catalyst, experiments have been carried out at a cutting reactor at different reaction temperatures, different molar feeding rates and different catalyst load rates. The highest conversion value was achieved at 70oC, the molar nutrition rate (alcohol/acid) was 9:1 and the catalyst load rate was 7% at 96.25% at the end of six hours. The catalyst is not damaged by the polar environment of the esterization reaction.  Therefore, it was repeatedly used eight times without losing its catalytic activity.
