中文摘要：

采用150μm的a-SiC为骨料，钾长石，高岭土，二氧化硅粉为粘结剂，利用正交试验通过半干压成型法制备出片状多孔支撑体，研究不同成型压力，活性炭造孔剂，粘结剂在1550℃的烧成温度下，多孔支撑体的孔隙率、弯曲强度和过滤压降的变化。当成型压力为6MPa，活性炭造孔剂含量质量分数为15％，粘结剂含量质量分数为20％时，支撑体的抗弯强度和气孔率同时增加；成型压力为12MPa，活性炭造孔剂含量质量分数为20％，粘结剂含量质量分数为20％时，支撑体的过滤压降和气孔率同时减小。结合正交试验调优结果和工程应用高强度而低过滤压降的原则表明：成型压力为12MPa,，活性炭造孔剂含量质量分数为15％，粘结剂含量质量分数为20％时，可获得孔隙率55．8％、弯曲强度为31．8MPa的SiO多孔陶瓷支撑体。当过滤速度为0．16m·h^-1时，该样品的过滤压降为2．9hPa。

英文摘要：

Using 150μm a-SiC powder as aggregate, the mixture of kaolin, potassium feldspar and silica as binder, based on orthogonal test method, the porous ceramics support was prepared by semi dry pressing at 1350℃. The porosity, flexural strength, and filter pressure drop of the porous ceramics support which was made in different forming pressure, employing activated carbon and binder were investigated.The flexural strengths generally decreased with increased porosity, and the filter pressure drop enlarged along with reduced porosity. However, under the pressure of 6 MPa, the porous ceramics support was obtained with 15 wt% activated carbon and 20% binderlthe flexural strength and porosity of which both raised. While under the pressure of 12 MPa, both the flexural strength and porosity of the support fabricated with 20% activated carbon and 20% binder declined. The optimization results of orthogonal test and the engineering application principle of high strength and small filtration pressure drop demonstrated that the porous ceramics support blend with 15% activated carbon and 20% binder owns 35.8% porosity, 31.8 MPa flexural strength under the pressure of 12 MPa, Concomitantly,the filter pressure drop of this sample is 2.9 hPa when filtration velocity is 0.16 m·h^-1.
