| description | 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.
