The objective of this study was to fabricate dual-layer hollow fiber as a microreactor for potential syngas production via phase inversion-based co-extrusion/cosintering process. As the main challenge of phase inversion is the difficulty to obtain defect-free fiber, this work focuses on the effect of the fabrication parameters, that is, nonsolvent content, sintering temperature and outer-layer extrusion rate, on the macrostructure of the produced hollow fiber. SEM images confirm that the addition of nonsolvent has successfully minimized the finger-like formation. At high sintering temperature, more dense hollow fiber was formed while outer-layer extrusion rate affects the outer layer thickness.
