Abstract

Kadar FFA dalam fraksi cair Palm Oil Mill Effluent (POME) berhasil diturunkan melalui reaksi esterifikasi. Kadar FFA turun dengan konversi 47,72% dari kadar awal sebesar 34,85% dalam kondisi reaksi perbandingan FFA : metanol 1:15 pada suhu 60°C selama 1 jam dan katalis sebanyak 5%. Katalis yang digunakan adalah Katalis Karbon Hidrotermal Tersulfonasi (Hydrothermal Carbon Sulfonate, HCS) dengan bahan baku nasi aking. Berdasarkan difraktogram sinar-X, HCS memiliki struktur yang amorf. Berdasarkan spektra IR, HCS memiliki gugus –SO3H dan –COOH sebagai gugus asam. Kuantitas asam HCS sebesar 0,84 mmol/g dan luas permukaannya 67,40 m2/g. ========================================================= FFA content in Palm Oil Mill Effluent has been decreased through esterification reaction. FFA content decrease with conversion 47.72% from 34.85% under condition FFA : methanol 1:15 at 60°C in 1 hour and 5% catalyst. The catalyst which is used in the reaction is Hydrothermal Carbon Sulfonate (HCS). This catalyst was produced from “nasi aking”. Based on X-ray diffractogram, HCS has amourphous structure. Based on Infrared Spectrum, HCS has –SO3H and –COOH functional group as acid group. Acid quantity of HCS is 0.84 mmol/g and surface area of HCS is 67.40 m2/g.
