当过氧化氢(H_2O_2)用作氧化剂时，在清除多余的H_2O_2时，往往需要快速分解H_2O_2。虽然已经在间歇反应器中研究了分解过程，但在停留时间为秒的固定床微反应器中从未进行过这一过程。与间歇式反应器相比，微反应器内的传质和换热得到了更高的分解效率。考察了微通道长度、流速、溶剂组成和气体压力等参数，建立了一级动力学模型。在几秒钟内，70%以上的 %的过氧化氢被成功分解。对催化剂钝化的挑战也进行了讨论。
The rapid decomposition of hydrogen peroxide (H2O2) is often desired in the cleanup of excess H2O2when it is used as an oxidant. Although the decomposition process has been studied in batch reactors, it has never been performed before in a fixed‐bed microreactor with residence time on the scale of seconds. With enhanced mass and heat transfer in microreactors, higher H2O2decomposition efficiency compared to batch reactors was obtained. A variety of parameters including length of microchannels, flow rate, solvent composition, and gas pressure were examined carefully and a first‐order kinetic model was established. Within a few seconds, more than 70 % of the H2O2was decomposed successfully. The challenge of catalyst passivation was discussed as well.
