PENGARUH KONSENTRASI REAKTAN TERHADAP KONVERSI LIMBAH PELEPAH SAWIT MENJADI ASAM LEVULINAT DENGAN METODE HIDROLISIS MENGGUNAKAN KATALIS ASAM SULFAT
Abstract
Palm frond could be hydrolyzed to levulinic acid using acid catalyst. In this study,
kinetics data and optimum condition of palm frond conversion to levulinic acid was
investigated. The conversion was conducted in ampoule as reactor (length of 150 mm,
I.D. of 4 mm and O.D. of 7 mm) over the following range of condition: palm frond
concentrations of 1-5 wt% (1-5 g/100 mL), temperature of 190 o C, sulfuric acid
concentrations of 1 M, and residence times of 0-240 min. The maximum LA yield is
approximately 9,38% (based on biomass weight) and 31,28% (based on cellulose
weight) was achieved for an initial palm frond concentration of 1 wt% (w/v), acid
concentration of 1 M, temperature of 190 o C, and residence time of 60 min. The result
showed that the concentration and yield of levulinic acid was affected by palm frond
concentration, but didn’t affect reaction rate.
