The first sub-project focuses on the development of a continuous multistage countercurrent fluidized bed absorber. The second sub-project focuses on the fabrication of active carbon (AC) spheres with high specific surface area, high sphericity and high attrition resistance. The first sub-project will be carried out by the NTUCGU team. They will use Discrete Element Method (DEM) coupled Computation Fluid Dynamics (CFD) to simulate the countercurrent fluidized bed absorber system. The effects of the particle diameter/hole diameter ratio, the plate opening ratio, the hole arrangement and size, the plate number, the gas velocity, and the mass flowrate of the AC spheres on the operation stability of the fluidized bed absorber will be evaluated. In the second sub-project, the spherical AC particles will be prepared by the CPCTTRI team. The in-house developed technique will be used to prepare AC spheres with different sizes from the CPC petroleum asphalt. The spheres will be oxy-cross linked, carbonated and activated. The Taiwan home-made AC particles can be prepared with desired size, porosity and durability. Finally, the prepared AC particles will be used as the Volatile Organic Compounds (VOCs) absorber in a continuous multistage countercurrent fluidized bed system. The system will be practically demonstrated based on the simulation predicted stable operations from the first sub-project and the durable AC spheres prepared from the second sub-project.球形活性碳;多階雙向流式流體化床;連續操作;揮發性有機物吸附;Active carbon spheres; Multistage countercurrent fluidized bed; Continuous operation; VOC absorption
