    Abstract

    Pemanfaatan sisa batang kelapa sawit (OPT) melalui kaedah pencecairan merupakan subjek yang diberikan perhatian. Ujikaji pencecairan OPT dalam etilena glikol dan gliserol, dengan pemangkin H2SO4, pada suhu 150 °C telah dijalankan berdasarkan rekabentuk eksperimen (DoE) dengan bantuan perisian Stat-Ease Inc., Design-Expert® Versi 7. Rekabentuk 24-1 pecahan faktoran telah digunakan di peringkat saringan di mana faktor-faktor seperti jenis pelarut, peratusan pemangkin asid sulfurik (H2SO4) dan masa pencecairan adalah penting kepada hasil pencecairan. Walaubagaimanapun, faktor stok suapan OPT dilihat kurang memberikan kesan. Faktor-faktor yang penting tadi beserta kesan percampuran pelarut pencecairan dikaji lebih lanjut dengan bantuan rekabentuk gabungan D-optimal. Proses pencecairan OPT dalam gliserol memberikan lebih banyak hasil berbanding dalam etilena glikol. Model yang telah dipilih ialah Linear (L) untuk campuran manakala 2–Faktor Interaksi (2FI) untuk proses. Ketika proses pengoptimuman dan pengesahan, keadaan eksperimen yang dicadangkan untuk hasil yang optimum ialah campuran 34% etilena glikol terhadap 66% gliserol, 4% H2SO4, dan masa pencecairan selama 116 minit. Utilization of waste oil palm trunk (OPT) through liquefaction is the subject of interest. Liquefaction of OPT in ethylene glycol and glycerol, with H2SO4 as a catalyst, at a temperature of 150 °C was carried out based on experimental design (DoE) aided by software Stat-Ease Inc., Design-Expert® Version 7. A 24-1 fractional factorial design used in screening phase showed that factors such as types of solvents, percentage of sulphuric acid (H2SO4) catalyst and liquefaction time found to be important. However, factor of OPT loading was found to be less important. Those important factors and different solvent mixtures were studied further by implementing combined D-optimal design. Liquefaction of OPT in glycerol found to give more yield than in ethylene glycol. The selected empirical model was Linear (L) for mixture, while 2–Factor Interactions (2FI) for process. For optimization and model verification, the proposed solution for an optimal result was a mixture between 34% ethylene glycol to 66% glycerol, 4% H2SO4, and 116 minutes liquefaction time.
