This work presented microfluidic processing of zeolite films in a capillary microreactor and its potential application for biomass conversion. Uniform and continuous HZSM-5 zeolite films were fabricated under a continuous flow hydrothermal system in which the film thickness could be precisely tuned by flow rate and synthesis time. The catalytic performance of this acidic HZSM-5 film capillary microreactor was evaluated by the continuous flow acetalisation reaction of glycerol with acetone, affording ∼62.61% solketal yield under mild and solvent free conditions. No deactivation was observed even after 100 h, indicating the excellent stability of this HZSM-5 film capillary microreactor. This microfluidic processing strategy provided an extended applicability in the fabrication of zeolite film-based capillary microchannels with a high length-to-diameter ratio or other chip-based microchannel devices.

在毛细管微反应器中对HZSM-5膜进行微流处理，以使甘油与丙酮连续缩醛化

这项工作介绍了毛细管微反应器中的沸石膜的微流体处理及其在生物质转化中的潜在应用。在连续流水热系统下制备了均匀且连续的HZSM-5沸石膜，该膜中的膜厚可以通过流速和合成时间精确调节。该酸性HZSM-5薄膜毛细管微反应器的催化性能通过甘油与丙酮的连续流缩醛化反应进行评估，在温和和无溶剂的条件下，缩酮的收率约为62.61％。即使在100小时后也未观察到失活，表明该HZSM-5薄膜毛细管微反应器具有出色的稳定性。
