Study of different titanosilicate (TS-1 and ETS-10) as fillers for Mixed Matrix Membranes for CO2/CH4 gas separation applications

Popis výsledku v původním jazyce

Three titanosilicate zeolites were used as fillers for Mixed Matrix Membranes: (i) ETS 10, (ii) TS 1 having Si/Ti = 100 and (iii) TS 1 using Si/Ti = 25. Zeolite samples were characterized by X-Ray Diffraction, Scanning Electron Microscopy, Atomic Emission Spectroscopy, X-Ray Photoelectron Spectroscopy, and CO2 and CH4 adsorption isotherms. TS 1 particles showed a narrow size distribution ranging from 200 nm to 400 nm. In the case of ETS 10, the size distribution was broader ranging from 400 nm to 800 nm. Mixed Matrix Membranes were prepared using Matrimid? polyimide as continuous phase and filler loadings of 10, 20, and 30 wt.%. Membranes were characterized by Thermogravimetric Analysis, Differential Scanning Calorimetry, and Scanning Electron Microscopy. The performances was measured at 8 bars of transmembrane pressure for CO2/CH4 mixed gases system at 50/50 vol./vol. concentration. Membranes using TS 1 (Si/Ti = 25) as filler showed a maximum increase of 89.1% of CO2 permeability and 23.9% increase in separation factor. In the case of TS 1 (Si/Ti = 100) only permeability increased significantly, with a maximum increase of 90.1%. Regarding the ETS 10 membranes, both permeability and separation factor increased slightly with respect to the reference polymeric membrane (22.5% in CO2 permeability and 7.8% in the separation factor). In conclusion, TS 1 (Si/Ti = 25) is the most suitable filler for the use in Mixed Matrix Membranes for gas separation applications among the titanosilicate studied in this work.
