Abstract

The purpose of this study was the development of a low-cost ceramic tubular membrane, using inexpensive materials, namely natural clay, and graphite as a porogenic agent . Such a low-cost membrane can be used as filters or porous supports for the preparation of multilayer ceramic membranes. Extrusion was used as a shape-forming method for this purpose. Graphite was selected as a porogenic additive. Raw materials were physicochemically and morphologically characterized. A comparative study of the influence of porogen content on membrane characteristics was carried out. Finally a graphite addition of 15 wt% and 850 °C as the sintering temperature were chosen. The obtained membrane had 41 vol% of porosity, diametral compression strength of 4 MPa, and relatively good corrosion resistance in basic and acid conditions. The performance of the membrane support was evaluated for diesel-in-water emulsion depuration as a function of pressure. Filtration test using 15% of porogen sample led to turbidity rejection factor of 95%. Therefore, it was considered that this membrane can be suitable for diesel/water emulsion treatment.

乳化液水柴油处理陶瓷膜的研制

本研究的目的是开发一种低成本的陶瓷管状膜，使用廉价的材料，即天然粘土，石墨作为致孔剂。这种低成本的膜可以用作多层陶瓷膜制备的过滤器或多孔支架。为此，采用挤压成形方法。选择石墨作为致孔添加剂。对原料进行了物理化学和形态表征。对比研究了孔隙素含量对膜特性的影响。最后选择石墨添加量为15wt %，烧结温度为850℃。所得膜的孔隙率为41%，直径抗压强度为4 MPa，在碱性和酸性条件下具有较好的耐腐蚀性。以压力为函数，评价了膜支撑对柴油水乳状液的净化性能。使用15%的孔隙样品进行过滤试验，浊度抑制系数为95%。因此，认为该膜可适用于柴油/水乳液处理。
