摘要
对不同Cu/Mn 物质的量比、不同焙烧温度和不同Al 含量的Cu - MnOx/Al2O3 制备的催化剂,研究了在不同的反应温度下CO2 加氢的反应活性。结果表明,当Al2O3 的物质的量分数在5 % ~10 % 。n(Cu) n( Mn) = 1 2 、焙烧温度400 ℃,反应温度260 ℃时,催化剂的活性较高。
In this paper,the influence of different mole ratio of Cu/Mn,Al 2O 3 content,calcination temperature and reaction temperature on the hydrogenation activity of carbon dioxide over Cu-MnO x/Al 2O 3 catalysts has been studied The changes of the Cu/Mn mole ratio,the content of Al 2O 3,calcination and reaction temperature are found to be very significant for the catalytic activity.Good catalytic activity and good methanol selectivity can be obtained when n(Cu)∶n(Mn)=12,Al 2O 3 content in catalyst is 5%~10%,and calcination temperature is 400 ℃
