| 00:00 | Sustainable Chemical and Biochemical Processes Through Continuous Synthesis and Separation Nopphon Weeranoppanant, Associate Professor, Burapha University, Thailand
Conventional chemical processes often involve the use of toxic reagents, high energy consumption, and inefficient step economy, posing sustainability challenges. To address this, our research group employs alternative catalytic systems such as biocatalysis and photocatalysis. Different strategies, including catalyst immobilization and hybrid separation-reaction systems, can be implemented to facilitate catalyst recycling and increase productivity. In this talk, demonstration of such strategies with continuous synthesis and separation will be discussed. | 00:00 | | Keynote Presentation Low Cell Voltage Electrosynthesis of Hydrogen Peroxide Kai Wang, Associate Professor, Department of Chemical Engineering, Tsinghua University, China
Electrochemical oxygen reduction reaction (ORR) via a selective 2e-
pathway offers a great opportunity for the synthesis of hydrogen
peroxide as an alternative of traditional anthraquinone route.
Unfortunately, the cell voltage of hydrogen peroxide electrosynthesis on
neutral condition still requires improvement to meet the industrial
demands, where high productivity and low input energy are desired. In
this report, crucial impacts of reactor component on the relationship of
cell voltage and current density and the over-potentials of each part
of a flow cell reactor for hydrogen peroxide electrosynthesis are
introduced, which indicate that the cathodic solution overpotential has
a great contribution to the cell voltage. When applying thin cathodic
solution channel, the hydrogen peroxide can be synthesized at 2.28 V
cell voltage with 300 mA/cm2 current density and 97.1% Faraday
efficiency, corresponding to an energy consumption of 3.70 kWh/kg H2O2,
which is much lower than the literature results. The produced hydrogen
peroxide can be directly used for synthesizing high purity
2,2'-dibenzothiazole disulfide, showing the potential industrial value
of hydrogen peroxide electrosynthesis technology.

An automatic single-liquid-slug oscillatory flow platform was
established for the kinetic investigation of photochemical reactions.
Reaction parameters including concentration, reaction time, light
intensity, pressure, and temperature were controlled precisely in an
automatic manner, and the reaction outcomes were obtained accurately
via, integration of an online HPLC. With the reaction kinetics
measurement performed for the photocatalytic oxidation of citronellol by
Ru(bpy)3Cl2 at a volume scale of 50 µL, it was demonstrated that the
single-liquid-slug oscillatory flow method was capable of achieving
material and time savings of 70% and 38% respectively as compared to the
conventional batch method, and of 80% and 62% respectively as compared
to the continuous flow method. The four reaction orders manifesting the
effects of the substrate concentration, photocatalyst concentration,
light intensity, and oxygen pressure, respectively, were attained as
well as the photoreaction rate constant. Furthermore, the kinetic data
obtained under a series of temperatures also shed light on the
photoreaction mechanism which exhibited a relationship between the
photoreaction rate constant and temperature that deviated from the
Arrhenius law. The approach developed in this work is especially useful
for the kinetic studies of photoreactions with relatively slower
intrinsic reaction kinetics, achieving a more resource-efficient
practice with higher repeatability and accuracy. |

| 00:00 | | Keynote Presentation Controllable Microfluidic Emulsions for Creating Functional Particles Wei Wang, Professor, School of Chemical Engineering, Sichuan University, China
Emulsion droplets play important roles in template synthesis of functional particles for various fields such as controlled release, catalysis, and separation. The features of emulsion droplets including their size and size distribution, shape, composition, and structure generally determine those features of the resultant particles and their functions for marvelous applications. This presentation introduces our recent works on microfluidic emulsification techniques for controllable emulsion production and functional particle synthesis. First, versatile microfluidic emulsification techniques for controllable generation of emulsion droplets from simple single emulsions to complex multiple emulsions are introduced. Then, rational synthesis of particles with controllable sizes, shapes, compositions, structures, and functions by using controllable emulsion droplets from microfluidics as templates are introduced. |
