Abstract

Porous Silica membrane in particular has some advantages which are high stability in thermal, mechanical and chemical. The pores size of the silica membrane is desirably controlled using sol gel method. Because of this advantage, it's suitable for gas separation at high temperature where membrane separation is highly desired from the view point of energy conservation in many chemical processes and also suitable for separating gas mixture through molecular sieving mechanism. This research project consists of two experiments; Preparation of a-Alumina Substrate and Preparation of Silica Membrane using sol gel method. For the first experiment the goal is to achieve 25 - 30% porosity of the substrate. There are two parameter that will be manipulated; addition of starch and sawdust into substrate. The results show addition of these two parameters will increase the porosity of the substrate which the maximum porosity is 22%. For the second experiment, nitric acid is used as a catalyst for silica sol preparation because of its low branched cluster that will result a narrower pore size. This experiment is divided into 3 part based on its dipping time; I hour, 2 hour and 3 hours. The results show the maximum separation factor of C02/Cf4; for I hour dipping time, the separation factor is l.I94, 2 hours (I.240) and for 3 hours (1.370).
