A new HPLC stationary phase, 1-methylnaphthalene modified Polystyrene-divinylbenzene resin (MNPSDVB), has been prepared to separate C60 and C70. High Column loading capacity and large separation factor of C60 and C70 were obtained in MNPSDVE column with the strong solvent, o-xylene, as the mobile phase.

It is shown from CFD simulation and particle image velocimetry (PIV) measurements that the flow field around ring packing is impacted by their height/diameter ratio and inclination. The results indicate that it is better to decrease the height/diameter ratio of ring packing to intersify the separation processes in the packing bed. Baded on a systematic study, a new Plum Flower Mini Ring (PFMR) was developed to meet the demands of separation column intensification. A comparison of the PFMR, Pall Ring and Intalox Saddle in a 600mm diameter column with an air-oxygen-water system over a wide range of liquid loads is presented. It was shown from the experiments that the PFMR had a much lower pressure drop, much larger throughput and better mass transfer efficiency than Pall Rings and Intalox Saddles.

Terminal velocity and mass transfer coefficient data for drop swarms were measured in a 0.1m diameter glass column filled with SMR (Super Mini Ring) packing, using a computerized video imaging system; 30% TBP-Kerosene/acetic acid/water and 50% imaging system; 30% TBP-Kerosene/acetic acid/water were us ed as the working systems. A unmber of techniques for the prediction of the observed mass transfer data were considered, and a new model to predict the mass transfer film coefficient, which accounts for the effects of surface contaminants on the mobility of the interface, is presented and shown to fit the experimental data. The effects of drop size and the presence of packing on ovelall dispersed phase mass transfer coefficient are presented. It is shown that overall dispersed phase mass transfer coefficient increases with increasing drop diameter, and decreases in the presence of SMR packing.
