Abstract The problems of process costs and pollution of residual waters in the textile industry require increasing attention due to the new ecological regulations and also those resulting from an economic point of view. Hence, the behavior of non-isothermal fixed-bed reactor applied for hydrogen peroxide decomposition by immobilized Terminox Ultra catalase attached onto the outer surface of glass beads was studied to determine the operational conditions at which hydrogen peroxide decomposition is most effectively. A dispersion model for bioreactor applied in this work, and verified experimentally, took into account the coupled mass and heat balances as well as the rate equation for parallel enzyme deactivation. The effect of feed temperature, feed flow rate, feed hydrogen peroxide concentration, and diffusional resistances were analysed. In the calculations the global effectiveness factor based on the external mass-transfer model developed previously was employed to properly predict the real bioreactor behavior.

使用分散模型预测生物转化的固定床反应器行为与平行酶失活：商业过氧化氢酶分解过氧化氢的案例研究

摘要 由于新的生态法规以及从经济角度产生的问题，纺织工业中的工艺成本和残留水污染问题需要越来越多的关注。因此，研究了非等温固定床反应器通过附着在玻璃珠外表面上的固定化 Terminox Ultra 过氧化氢酶分解过氧化氢的行为，以确定过氧化氢分解最有效的操作条件。在这项工作中应用并通过实验验证的生物反应器分散模型考虑了耦合的质量和热平衡以及平行酶失活的速率方程。分析了进料温度、进料流速、进料过氧化氢浓度和扩散阻力的影响。
