A forced through flow membrane-reactor was used to study the formaldehyde catalytic oxidation process, dissolved in oxygen-saturated aqueous solution. The commercial support was modified layer by layer with polycations and polyanions; the active phase of the catalytic membrane was gold nanoparticles dispersed over the macroporous surfaces of the membrane. Formaldehyde oxidation was performed at 30 and 60 °C with three different formaldehyde concentrations, namely: 100, 300 and 500 ppm. The best performance 59% conversion was achieved for an initial 500 ppm after 240 reaction minutes. The reaction products were determined by GC. The catalytic membrane reactor shows good performance for the removal of formaldehyde at low temperature.

使用强制流通膜反应器研究溶解在氧饱和水溶液中的甲醛催化氧化过程。用聚阳离子和聚阴离子逐层修饰商业载体。催化膜的活性相是分散在膜大孔表面上的金纳米颗粒。甲醛氧化是在30和60°C下以三种不同的甲醛浓度（即100、300和500 ppm）进行的。在240分钟的反应后，最初的500 ppm达到了最佳性能59％的转化率。反应产物通过GC确定。催化膜反应器在低温下表现出良好的脱甲醛性能。
