The compact design of OzBiONY® system was successfully developed. The system is user friendly and safe for laboratory operation with automatic setting system equipped with exhaust fan. The dry ozone was supplied into the biomass surface in the horizontal reactor equipped with ribbon mixer and washing with NaOH for complete separation. The experimental results revealed 2.20 g/g material of glucose concentration yield was collected for pretreated OPF compare to 1.65 g/g material of glucose concentration yield for untreated OPF at moderate process conditions. By using dilute H2SO4 (4 wt%) as catalyst at moderate process condition (180°C, 1h), 2.5 wt.% LA yield was obtained using untreated OPF. In contrast, the hydrolysis process was enhanced by using ozonolysis pretreated OPF with the LA yield obtained was 13 wt.%, comparable with LA yield attained from commercial cellulose as feedstock (14 wt%). The new prototype pretreatment system is one-step closer to being commercialized.
