- 摘要:
- 通过理论分析和试验对一种新型整体式层板催化剂床进行了研究。设计了催化 剂床流道结构并对催化剂床的加工工艺进行了初步研究。热试车结果表明,催化剂床性能良 好,最高床载可达16.59/(em2·s),分解效率96%,室压粗糙度小于±2%,催化剂床累计工作 寿命大于455s。性能未出现下降趋势。
- Abstract:
- A new kind of hydrogen peroxide integrated platelet catalyst bed is investigated based on theoretical analysis and experiment.The flow path of platelet catalyst bed was designed. The production techniques of the platelet catalyst bed,such as photoetching technique,silver plating technique and the diffusion welding technique are investigated.Finally,the successful hot—firing tests were performed.The investigation results indicate that this kind of catalyst bed has good performances: its high bed loading can be up to 16.59/(cm2·S),the decomposition efficiency is 96%, the roughness of chamber pressure is below 2%and the catalyst bed accumulated endurance time more than 455s at different operating conditions without any measurable performance changing.
