本文研究了硅胶载体扩孔的最佳工艺条件,即考察扩孔液组分、酸度、扩孔压为(或温度)、扩孔时间等因素对扩孔后载体微孔结构的影响,引用有关理论分析,进行了实验验证,为催化剂设计及改进提供了有关依据。不同扩孔条件下得到的载体,制备成合成1,4-丁炔二醇的铜铋催化剂(φ5mm),用转框反应器及涓流床外循环微分反应器考评,表明扩孔后制成的催化剂在相同炔化反应条件下,活性有显著提高。 In this paper, silica gel carrier reaming the optimum process conditions, namely, investigating the composition of reaming fluid, acidity, expanding the pore pressure (or temperature), reaming time and other factors on the pore structure of the carrier after reaming, citing relevant Theoretical analysis, experimental verification, provide the basis for catalyst design and improvement. The catalyst obtained under different conditions of expanding the pores was prepared into a copper bismuth catalyst (φ5mm) for synthesis of 1,4-butynediol, which was evaluated with a turret reactor and a trickle bed differential recycle reactor, which indicated that after reaming Of the catalyst under the same alkyne reaction conditions, the activity was significantly increased.
