中文摘要：

在微尺度催化燃烧中，添加氢气能够有效拓展可燃范围，改善燃烧。本文为了解决微燃烧中氢气源的问题，针对乙醇在低停留时间下催化重整制氢特性进行了实验研究。针对气化与重整采用单一热源供热的情况，研究了不同乙醇流量，以及添加水等情况下重整产氢的情况。本文还针对气化做了讨论。在实验中采用Cu／Zn催化剂。结果表明，在600K左右能产生O．1mL／s的氢气，基本满足下游微尺度燃烧的需求。乙醇／水的混合物的重整实验表明，水不参与重整反应，且会增加气化负担。在所有实验中，均未在尾气中测量到CO和C02，这表明在采用这种催化剂的情况下，反应产物主要为C和H2，存在比较严重的积炭。

英文摘要：

In micro catalytic combustion, hydrogen addition can enlarge the flammable range and improve the combustion performance. Focusing on the hydrogen source, this work experimentally studied the hydrogen production of ethanol reforming with a short residence time. With a single heat source for vaporization and reforming, the hydrogen production characteristics with different ethanol flow and different water addition were studied. And the vaporization of the mixture was also discussed. Cu/Zn catalyst was employed in experiments. The results indicated that 0.1 mL/s hydrogen can be produced under 600 K conditions, which are enough for micro-combustion downstream. Experiments with ethanol/water mixture indicated that water are not reacted and is negative for vaporiza- tion. CO and C02 were not detected in the exhaust gases in all experiments. This phenomenon indicates that main products in reforming reaction are C and H2, and there are notable carbon deposits.
