Ceramic hollow fiber membrane distributor for heterogeneous catalysis: Effects of membrane structure and operating conditions

Recent Progresses in Ceramic Hollow‐Fiber Membranes

“…Although ceramic hollow-fiber membranes have many advantages over other hollow-fiber membranes, more studies should be conducted for the mass production of these membranes at low costs.

“…Meng et al [65] developed a ceramic hollow-fiber membrane distributor for the micro-scale distribution of reactants in heterogeneous catalytic reaction. To investigate the feasibility of the membrane ceramic hollow-fiber membrane-based reactant distribution, phenol hydroxylation with hydrogen peroxide (H 2 O 2 ) over TS-1 solid catalysts was a model reaction.…”

Development of a hollow fiber membrane micro-reactor for biocatalytic production of formate from CO2

“…Ventilation (1) and (2) are controlled by the micro-structure parameters and surface property of HFMs [20]. Considering that hydrophilic materials may cause membrane wetting and bring unnecessary diffusion resistance of CO 2 gas through the membrane pores, several common hydrophobic microporous materials, PP, PE, PTFE and PVDF were chosen as the ventilation membranes.…”

“…The porous-plate sparger produces more even bubbles than the above-mentioned two types of spargers and has been extensively applied [19]. The microporous membrane has unique advantages, such as smaller and denser bubbles, a larger gas-liquid contact surface area and more controllable structure [20]. Du et al developed a membrane-dispersion micro-reactor for the controllable preparation of SiO 2 nanoparticles, in which a Ni microfiltration (0.2 mm) flat sheet membrane was used as the dispersion medium of pure NH 3 and exhibited excellent micro-mixing [21].…”
