In this study, the impact of ozonation abetted with the citric acid pretreatment (OZCAP) method on fruit waste was investigated for ameliorating hydrogen production. Initially, the ozonation pretreatment (OZP) method was performed by varying ozone (O₃) dosage and disintegration time. At optimized conditions (O₃ dosage (0.04 g/g suspended solid; SS) and disintegration time (40 minutes)), 17.6% of liquefied organics emancipate rate (LER) and 13.5% of SS reduction were perceived. Further augmenting LER of fruit waste, OZCAP method was proceeded by varying citric acid dosage and disintegration time at an optimized OZP dosage (0.04 g/g SS). A higher LER (24.4%) and SS reduction (19%) were described at an optimal citric acid dosage (0.03 g/g SS) and disintegration time (20 minutes). Then, the hydrogen production potential of OZCAP, OZP and raw fruit waste were evaluated in which OZCAP method exhibited a higher cumulative hydrogen production (30 mL/g volatile solids). Energy valuation reveals that OZCAP method exhibited a net energy of 3.7 kWh/kg of fruit waste.

在这项研究中，研究了柠檬酸预处理 (OZCAP) 方法促进的臭氧化对水果废料的影响，以改善氢气的产生。最初，臭氧预处理 (OZP) 方法是通过改变臭氧 (O ₃ ) 剂量和分解时间来进行的。在优化条件下（O ₃剂量（0.04 g/g 悬浮固体；SS）和崩解时间（40 分钟）），17.6% 的液化有机物释放率（LER）和 13.5% 的 SS 减少。进一步增加水果废料的 LER，OZCAP 方法通过在优化的 OZP 剂量（0.04 g/g SS）下改变柠檬酸剂量和崩解时间来进行。在最佳柠檬酸剂量 (0.03 g/g SS) 和崩解时间 (20 分钟) 下，描述了更高的 LER (24.4%) 和 SS 减少 (19%)。然后，评估了 OZCAP、OZP 和生水果废料的产氢潜力，其中 OZCAP 方法表现出更高的累积产氢量（30 mL/g 挥发性固体）。能量评估表明，OZCAP 方法显示的净能量为 3.7 kWh/kg 水果废料。
