Applied Environmental Research

This research aimed to evaluate the effect of the type of solvent, pH, substrate loading, and reaction time on the chemical components of palm empty fruit bunches (EFB). Steam pretreatment was set up at a temperature of 121 °C and pressure of 1.18 bar, using an autoclave with substrate loading of 5, 10, 15 and 20 % w/v at reaction times of 15 and 60 min. Distilled water, waste glycerol, alkaline glycerol and acidic glycerol were compared as solvents during steam pretreatment. The results showed that with distilled water, better pretreatment was achieved at 5 % and 10 % loading …
