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。
In this experiment, the use of trickle bed reactor 2-ethylhexen-2-ene catalytic hydrogenation of 2-ethylhexanol small test and test equipment, and achieved a catalytic activity and liquid space velocity and catalyst bed height , And the least square method was used to obtain the empirical formula under operating conditions respectively: LHSV ~ (-2/3) = - 0.206-16.853 log (A_i) / (A_o) log (A_i / A_o) = -0.027-0.0027 L ~ (-1/3) From the above equation, the maximum liquid space velocity and the minimum catalyst layer height at the time of conversion of the reactants to the product under operating conditions are obtained. The relationship between the obtained catalytic activity and liquid space velocity is consistent with the literature. The experiment shows that the change of hydrogenation effect obtained by the change of bed height is caused by the change of liquid mass flow rate. The experimental data obtained for the trickle bed reactor development, design, operation is beneficial.
