摘　　要：载体和钴物种之间的相互作用对费托钴催化剂分散度和还原度具有重要影响,载体改性可以调节载体与钴物种之间的相互作用。简要介绍了费托合成钴催化剂载体改性技术及其对载体与钴物种相互作用的影响,结果表明:改性载体和钴物种之间相互作用增加时,分散度升高,还原度降低;改性载体和钴物种之间互相作用降低时,则分散度降低,还原度升高;通过多载体掺杂改性、无机助剂改性及载体表面有机改性可有效调节载体和钴物种之间的相互作用,使得催化剂具有适中的还原度和分散度,从而提高催化剂的活性。In order to strengthen the interaction between supporter and cobalt catalyst,meanwhile,enhance the reducing capacity of catalyst,the supporter was modified.The modification technologies and their influence on the interaction between supporter and cobalt catalyst were introduced.The results showed that,when the interaction was enhanced,the dispersity of catalyst was strengthened and the reducing capacity was weakened.The above two properties of catalyst changed in the opposite trend when the interaction was lowered.By multi-supporter doped modification,inorganic additives and supporter surface organic modification technologies,the interaction between the supporter and cobalt species could be effectively regulated.
