Preparation of fused silica membrane with high performance for high temperature gas filtration by sealing and spray coating
Source abstract
Abstract
Abstract In order to improve the gas permeability and thermal shock resistance of the ceramic membranes applied in high temperature gas-solid separation techniques, fused silica and graphite particles were used as the primary raw material and pore-former agent, and the spray coating based-on PVA sealing was applied to prepare the separation membrane. These approaches remarkably decreases filtration resistance by increasing support permeability and reducing the intrusion of ceramic membrane forming particles into the support as well as the thickness of the membrane. The fabricated membrane had an average pore diameter of 9.85 μm and a gas permeability value of 8.2 × 104 m3/(m2 h bar), its dust removal efficiency reached 98.6%.
