Catalytic wet peroxide oxidation of dissolved natural organic matter (NOM) has been optimized in a continuous-flow, fixed bed reactor by using an extruded Al/Fe-pillared clay catalyst using a Synthetic Surrogate of NOM (SS-NOM) resembling typical composition and molecular weight distributions in real surface waters. Proper humidity of the extrudate’s precursor mix was found to be 38 %. Mass fraction of catalyst (x_c = 0.5), absolute humidity (H = 0.6), and a height/diameter ratio = 2.0 (particle ϕ ∼ 3.0 mm and height ∼ 6.0 mm) showed the best combined mechanical and textural properties (compression strength 121 N, tenacity 1.1325 mJ, attrition 1.45 (%), BET surface 76 m²/g, and microporous surface 52 m²/g) and catalytic performance. The main parameters governing the catalytic wet peroxide oxidation (height of the catalyst bed and the ratio (H₂O₂/SS-NOM) were optimized in terms of mineralization of the total organic carbon and H₂O₂ reaction efficiency, under constant and rather short 9.2 min of residence time. Inlet concentrations of the SS-NOM (TOC = 6.63 – 13.7 mg C/dm³), pH (5.9 – 7.8) and temperature (20.0 °C – 24.0 °C) were covariates within the typical ranges exhibited by surface waters. The optimal multi-response catalytic performance using desirability function (d = 0.73) displayed 24.3 % of TOC mineralization and 51.2 % of reacted H₂O₂ with a height of catalyst bed 22 cm and inlet ratio (H₂O₂/SS-NOM) = 5.9 (mg H₂O₂/mg TOC), room temperature (20.0 ± 1.0 °C), and circumneutral pH.

在连续流固定床反应器中，通过使用挤压的Al / Fe柱状粘土催化剂（采用类似于典型组成的NOM的合成替代品（SS-NOM）），对溶解的天然有机物（NOM）的催化湿式过氧化物氧化进行了优化。实际地表水中的分子量分布。发现挤出物的前体混合物的适当湿度为38％。催化剂的质量分数（x _c = 0.5），绝对湿度（H = 0.6）和高度/直径比= 2.0（颗粒ϕ〜3.0 mm和高度〜6.0 mm）显示出最佳的机械和组织性能组合（压缩强度） 121 N，韧度1.1325 mJ，损耗1.45（％），BET表面76 m ² / g，微孔表面52 m ²/ g）和催化性能。在总有机碳矿化和H ₂ O ₂反应效率方面，优化了控制湿式过氧化物催化氧化的主要参数（催化剂床的高度和比例（H ₂ O ₂ / SS-NOM））。停留时间较短，仅为9.2分钟； SS-NOM的进口浓度（TOC = 6.63 – 13.7 mg C / dm ³），pH（5.9 – 7.8）和温度（20.0°C – 24.0°C）是典型范围内的协变量。利用合意函数（d  = 0.73）的最佳多反应催化性能显示TOC矿化度为24.3％，反应的H ₂ O为51.2％₂与催化剂床的高度22厘米和入口比（H ₂ ö ₂ / SS-NOM）= 5.9（毫克ħ ₂ ö ₂ /毫克TOC），室温（20.0±1.0℃），和circumneutral pH值。
