Effect of ozonolysis and thermal pre-treatment on rice straw hydrolysis for the enhancement of biomethane production

Sustainable application of rice-waste for fuels and valuable chemicals-a mini review

“…Solid-state fermentation was applied in producing biohydrogen from rice husk by Tosuner et al, and they found that the volume and yield of biohydrogen formation increased with decreasing particle size of rice husk, the highest biohydrogen formation volume was 29.26 mL under the particle size of <74 μm (yield: 5.9 mL/g substrate ) ( Tosuner et al, 2019 ). In producing biomethane from rice waste, optimizing the thermal pretreatment, ozonolysis induction and anaerobic co-digestion can enhance the productivity ( He et al, 2017 ; Patil et al, 2021 ). In anaerobic digestion process, high thermal pretreatment temperature (e.g., 210°C) may cause longer biogasification period due to the formation of byproducts, thus He et al found a proper thermal pretreatment temperature (150°C) achieving biomethane yield of 134 mL/(g- Volatile solid added ) ( He et al, 2017 ).…”

Valorization of agricultural wastes for biofuel applications

“…The addition of Aspergillus - and Neurospora -based additives in an enzymatic pretreatment increased the anaerobic digestibility of the substrate and ensure a yield of516 mL/g VS. In another study, Patil et al. (2021) employed ozonolysis and thermal pretreatments to synthesis biomethane from rice straw.…”

Synthesis of bismuth oxyhalide (BiOBrzI(1-z)) solid solutions for photodegradation of methylene blue dye

“…Therefore, there is a need to employ a method that is effective, less costly, and environmentally friendly. Oxidative processes such as photocatalysis, the Fenton method, photolysis, sonolysis, sonocatalysis, sonoFenton, photo-Fenton, and ozonolysis 5,[9][10][11][12][13][14][15][16][17] have recently been explored. Among these, photocatalysis, which depends on in-situ photogenerated positively charged holes (h + ), hydroxyl radicals ( • OH), negatively charged electrons (e−), superoxide radicals ( • O 2 − ) has been demonstrated to be promising in terms of cost, toxicity, recyclability, mild reaction conditions, ease of operation, efficiency, and high degradation ability [18][19][20][21][22][23] .…”
