Asymmetric porous cordierite hollow fiber membrane for microfiltration

Recent Progresses in Ceramic Hollow‐Fiber Membranes

“…This result was in line with the work of Liu et al [57] and Liu et al [27] in preparation of TiO 2 /Al 2 O 3 composite hollow-fiber membranes. This result was consistent with the research of Zhang et al [55]. Liu et al [57] showed that in preparing of SrCe 0.95 Yb 0.05 O 3-α (SCYb) membranes, as the sintering temperature increased from 1350 to 1550°C, the mechanical strength gradually decreased.…”

“…Zhang et al [55] studied the effect of sintering temperature on the porosity, pore size distribution, microstructure, gas permeability, bending strength, and thermal expansion of an asymmetric porous cordierite hollow-fiber membrane. Zhang et al [56] investigated the influences of sintering temperature on the microstructure, porosity and pore size distribution, bending strength, and pure water flux.…”

“…Zhang et al [55] indicated that when the particle size of cordierite powders was large, cordierite hollow-fiber membranes with the inner macro-void structure and the outer thin spongelike structure were obtained. This kind of structure could be used for the actual application of cordierite hollow-fiber membranes.…”

“…Zhang et al [55] prepared cordierite hollow-fiber membranes. The spinning suspension consisted of cordierite powder, N-methyl-2-pyrrolidone (NMP) as solvent, polyethersulfone (PES) as polymer binder, and polyvinylpyrrolidone (PVP) as additive.…”

Funky inorganic fibers

“…Traditionally, inorganic porous hollow fibers have been used as membrane (supports), depending on the specific pore size of the fiber. A wide range of membrane applications is envisioned, such as for example water desalination [76], membrane distillation [82,83], pervaporation [83][84][85][86][87], water treatment [88,89], membrane extraction [90,91], organic solvent nanofiltration [10,84], microfiltration [19,60,63,67,[92][93][94], gas separation [27, 73-75, 80, 93, 95-97] or as a membrane bio reactor [17,98]. Additionally, fibers have been used as a catalyst support by deposition of a catalyst on the fiber's surface [12].…”
