Abstract

Dalam penelitian ini dilakukan proses hydrothermal liquefaction limbah distilasi bioetanol generasi-2 dari tandan kosong kelapa sawit. Penelitian difokuskan untuk mengetahui pengaruh parameter-parameter fisik dan kimia terhadap karakteristik produk liquid yang dihasilkan. Untuk parameter fisik yang diamati adalah suhu (250–310°C) dan waktu proses (0-120 menit), sedangkan untuk parameter kimia akan diamati pengaruh penambahan katalis Na₂CO₃ dan K₂CO₃ (0-20%). Berdasarkan hasil analisa elemental dan perhitungan nilai kalor, suhu dan waktu proses optimum adalah 270°C dan 30 menit. Penambahan katalis Na₂CO₃ dan K₂CO₃menyebabkan turunnya nilai kalor dari produk liquid dan memperlihatkan pola yang fluktuatif. Sementara itu, senyawa kimia yang terkandung dalam produk liquid berdasarkan hasil analisa GC-MS adalah 2,3-butandiol; asam asetat; aseton; etanol; gliserin; fenol; 2,6-dimetoksi fenol; 2-metoksi fenol dan propilen glikol. Semakin besar konsentrasi katalis Na₂CO₃ meningkatkan konsentrasi etanol dalam produk liquid, yakni mencapai sekitar 16 mol % Carbon pada 20% Na₂CO₃. Sedangkan penggunaan katalis K₂CO₃tidak memberikan pengaruh yang signifikan.
