%X 采用无定形SiO2为载体,制备出蛋壳型F-T合成催化剂。利用SEM、EDS等技术考察了钴基催化剂的结构和还原性能。结果表明,催化剂的反应活性在很大程度上取决于可利用的氧化钴的量。助剂ZrO2的添加有利于提高催化剂的分散程度、催化活性及C5+选择性。 Cobalt-based eggshell catalysts were prepared from support of formLess SiO2. The structure and reduction property of the catalysts were characterized by SEM,EDS,and BET techniques. The results show that the catalysts' reacting activity depends on available oxide cobalt amounts to a great extent. Additive of ZrO2 is beneficial to improve dispersing degree,catalysis activity and selectivity for C+5 hydrocarbon
