In a typical synthesis 1,0 g of catalyst is placed inside of an ¡®¡®U¡¯¡¯-shaped quartz and heated up to 750 8C in nitrogen atmosphere, then the ethylene at 300 cm3 /min is diluted in nitrogen at 100 cm3 /min and flowed through the tube for 30 minutes. After, the furnace is cooled down to room tempera?ture the product is removed. When iron is deposed on mesoporous silica, a previous reduction of the catalyst is carried out with 50 cm3 /min of H2 in 150 cm3/min N2 for 15 minutes. ·¢×ÔСľ³æAndroid¿Í»§¶Ë |
