Study on Reverse Micro emulsion Method Applied in Preparation of Catalyst MnBaAl_(11)O_(19-?) for Dimethyl Ether Combustion

摘要

Reverse micro emulsion method showed some advantages in the preparation of the catalyst MnBaAl_(11)O_(19-?) with large surface area and high activity, when compared with sol-gel method or co-precipitation method. The influences of water content in reverse micro emulsion on nanostracture catalyst MnBaAl_(11)O_(19-?) were discussed in this paper. The catalyst MnBaAl_(11)O_(19-?) was prepared by reverse microemulsion method with a system consisted of 55% of n-heptane, 15% of emulsifier OP-10, 15%) of 1-octanol and 15% of water (volume ratio).
