摘要: 通过线性实验与正交实验探讨了交联剂用量、致孔剂用量及致孔剂种类三个因素对疏水催化剂载体SDB的孔径、比表面积及硬度的影响。结合氮气等温吸脱附曲线的迟滞回线与SEM形貌结果分析了SDB载体的孔结构。结果表明，使用非良溶剂作为致孔剂时，随致孔剂分子量而增加，SDB的孔径同步增大而硬度明显降低；高DVB用量有利于获得均匀的孔结构及较高的机械强度，但孔径偏小。致孔剂类型与用量对SDB的疏水性的影响大于交联剂用量对其的影响，这表明微观结构对SDB的疏水性有着更为直接的影响。部分SDB表层的孔径小于内部，存在着瓶颈结构。
Abstract: Through linear experiments and orthogonal experiment, the influence of three factors on the pore size, specific surface and hardness of hydrophobic catalyst carrier SDB was discussed, including the amount of crosslinking agent, porogen and the type of porogen. Based on the hysteresis loop of N2 isothermal adsorption-desorption curve and surface morphology, the pore structure of the catalyst support was analyzed. The result shows that the higher crosslinking agent amount is beneficial to obtain uniform pore structure and higher mechanical strength, but the pore size is smaller. The influence of the type and amount of the porogen on the hydrophobicity of the carrier is greater than that of the crosslinking agent, which indicates that the microstructure has a more direct influence on the hydrophobicity of the carrier. The pore size of the partial carrier surface is smaller than that of the interior, indicating the presence of bottleneck structures.
