摘要: 本实验采用涓流床反应器在2-乙基己烯-2-醛催化加氢制2-乙基己醇小试和模试装置中,取得了催化活性与液体空速和催化剂床层高度的关系,并运用最小二乘法分别得到在操作条件下的经验公式: LHSV~(-2/3)=-0.206-16.853log(A_i)/(A_o) log(A_i/A_o)=-0.027-0.0027L~(-1/3) 由上式可得出在操作条件下反应物转化为产品时的最大液体空速及最小催化剂层高度。所得到的催化活性对液体空速的关系与文献相符。实验认为由床层高度的变化所取得的加氢效果的变化是由于液体质量流速的变化而引起的。 本实验所得的数据对于涓流床反应器的开发、设计、操作是有益的。

Abstract: 2~ethyl-2-hexenal was hydrogenated to 2-ethyl hexanol in both laboratory and pilot equipment. Trickle bed reactors were used. We find that log is proportional to (LHSV) 3 and L 3 , where L is the height of catalyst bed. It is shown that their relationship under operating conditions can be expres- sed as follows.(LHSV)-2/3 =-0.206-16.853log. and logAi/A0=-0.027-0.0027 L 1/3 From these formulae the greatest LHSV and minimum catalyst bed height under operating conditions at which reactants can completely convert into products are calculated. The formula showing the relationship between catalytic activity and LHSV agrees with that in literature. The variation of the catalyst bed height will affect the result of hydrogenation, which is mainly due to the change of liquid rate. The data obtained are useful for development, design and operation of trickle bed reactors.
