Sub/supercritical liquefaction of oil palm fruit press fiber for the production of bio-oil: Effect of solvents

Bio-oil production from oil palm biomass via subcritical and supercritical hydrothermal liquefaction

“…The selection of biomass to water ratio of 1:10 in this study was based on the works reported in the literature, in which liquefaction experiments were optimized at this condition [14,[22][23][24][25]. The average weights of biomass feedstock and distilled water loaded into the reactor are shown in Table 3.…”

An overview of the oil palm industry in Malaysia and its waste utilization through thermochemical conversion, specifically via liquefaction

“…With the aided of respond surface methodology (RSM) software, it was found that the optimal condition for thermal decomposition of FPF was recorded at temperature 278 1C, of 5 g specimen loading with the particle size ranged from 0.7 to 1 mm and residence time of 40 min. Mazaheri et al [154] further studied the decomposition of FPF as the effects of polar protic and dipolar aprotic solvents in a sub/supercritical environment. They used a high-pressure autoclave reactor, and liquefied FPF in sub/supercritical methanol, ethanol, acetone, and 1,4-dioxane treatments.…”

Sweet sorghum stalk liquefaction in supercritical methanol: Effects of operating conditions on product yields and molecular composition of soluble fraction

“…It is well known that high pressure could increase solvent density [34]. High-density methanol efficiently penetrated into biomass interior to facilitate decomposition and extraction of macromolecules in biomass [35,36].…”
