Representative Research
1. A new type of slurry reactor integrating mixing and separation was invented for solid catalyzed reactions by combining the unique advantages of airlift loop reactors and hydrocyclones, and the process intensification of fluid flow and separation was achieved. In these slurry reactors, the solid catalyst particles can be retained for a long designed time, avoiding the solid-liquid separation, assuring the continuous production, and reducing the costs.
2. A new type of slurry reactive crystallizer was invented for crystallization of the non-spherical particle by combining the airlift loop reactor and the hydrocyclone, and the grain size distribution and the morphology of the crystal can be adjusted accurately. They are employed to synthesize calcium carbonate whiskers on a large scale without adding any chemical additives for crystal-form modification.
3. A commercial cathode material of NCM 811 with concentration gradient was developed, and a set of efficient types of equipment and process design package for sintering and preparing the precursors with high controlling accuracy are invented.
4. An efficient airlift fermentor was developed with high efficiency of oxygen transfer, and the circular fluid flow in all the time during the fermentation was solved for the bach culture.
5. For the separation of solid particles from the liquid phase, an energy-efficient hydrocyclone with a small diameter was developed. Additionally, for the smart separation of gas-liquid-solid in the slurry reactor, and a conceptual design of separator with fluid circulation-solid sedimentation-siphonage discharge was proposed.
6. A new photobioreactor with high photosynthetic efficiency and low energy consumption was invented; it needs low capital and operating costs and can be employed with a long life span.
