Abstract

Micro-packed bed reactors (μPBRs) with pillar structures have the advantages of low pressure drop and energy consumption. Studies of liquid holdup and mass transfer were vital issues for the deeper understanding of μPBR with pillar structure and guiding reactor design. However, rapid characterization technology and platform need to be taken into consideration for improving research efficiency. In this work, liquid holdup and mass transfer of μPBR with pillar structure were characterized utilizing image processing and colorimetric techniques. Effects of two pillar structures with different diameters and interstitial spaces were evaluated. The heterogeneities of local mass transfer characteristics from spatial dimension were revealed in the μPBR with pillar structure. Outstandingly, a highly integrated software platform with friendly Graphical User Interface was constructed, achieving online acquirement and analysis of data efficiently. Furthermore, the self-designed software platform presented enormous potential for high-efficiency reactor design and optimization.

利用集成软件平台快速表征柱状结构微填料床中的液含率和传质

采用柱状结构的微填料床反应器具有压降低、能耗低等优点。研究液含率和传质是深入了解柱状结构μPBR和指导反应器设计的重要问题。然而，为了提高研究效率，需要考虑快速表征技术和平台。本文利用图像处理和比色技术对柱状结构μPBR的液含率和传质特性进行了表征。对两种不同直径和间距的柱状结构的效果进行了评价。柱状结构μPBR在空间尺度上表现出局部传质特性的异质性。突出的是，构建了一个高度集成的软件平台，具有友好的图形用户界面，实现了数据的在线采集和分析。此外，自主设计的软件平台为高效反应堆的设计和优化提供了巨大的潜力。

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
