Porous ceramicsupports were elaborated from natural kaolino-illitic clay, before and after acid activation, using uniaxial dry pressing method. The prepared supports were sintered at 850, 900 and 1000°C. The effect of sintering temperature on the mechanical strength, density, porosity, pore size distribution and permeability was evaluated. It was observed that with increase of sintering temperature,...
In this work, nanofibrous ultrafiltration (UF) membrane based on natural clay (attapulgite, AT) nanofibers for oil/water emulsion separation was fabricated through a combination of papermaking and sintering technologies. The effects of sintering process and poly (vinyl alcohol) (PVA) content on the pore structure, wetting ability and mechanical property of AT-based nanofibrous membranes (NFMs) were...
