Alkaline hydrogen peroxide pretreatment of cladodes of cactus (opuntia ficus-indica) for biogas production

Abstract: The alkaline hydrogen peroxide (AHP) pretreatment of cladodes of cactus (Opuntia ficus-indica) for biogas production was evaluated based on the delignification of cladodes of cactus. The effects of alkaline hydrogen peroxide concentration (30% w/w solution) and the pretreatment time (3, 6, 9, and 12 h) were evaluated at pH 11.5, temperature of 30 °C, and 180 rpm for removal of lignin. A batch of anaerobic digestion experiments were conducted at mesophilic temperature conditions (37 ± 1 °C) with the … Show more

“…The LHV results were in the range of 14.76-15.02 kJ.kg -1 , while the HHV results were in the range of 15.13-15.53 kJ.kg -1 . The negative effect of ash on the calorific potential of lignocellulosic biomass has already been reported in studies by Protásio et al [27] and Belay et al [28]. ring (890 cm -1 ) [30].…”

“…The interest in bio-based cactus materials is growing, which is reflected in the number of publications. Belay et al studied the cactus species Opuntia ficus-indica, used for biogas production [25]. The use of cacti and banana peels as a natural coagulant for drinking water treatment was investigated in the study by Kalibbala et al [26].…”
