摘要：

Ce0.8Zr0.2O2 supported Pt catalyst was arranged as packed-bed in micro-cylindrical quart tube to investigate premixed n-heptane/air catalytic combustion characteristics, including catalytic activity, combustor wall temperature, maximum tube wall temperature, conversion rate and surface heat loss. Catalytic activity experimental results show that ignition temperature of n-heptane in Φ=0.5 is 452 K, and catalytic combustion can be achieved under 500 K. In self-sustaining experiment, maximum wall temperature shifts downstream and high temperature zone expands. Maximum tube wall temperature of Φ=0.5 and 1 experience sharp drop in Re=125. Results indicate that When Re is fixed, working condition of Φ=1 acquires higher maximum wall temperature and conversion rate, lower surface heat loss than that of Φ=0.5, which means working condition of Φ=1 is more suitable in micro-combustors. © 2016, Zhejiang University Press.
