| Description
| - In this work, Titanium Silicalite 1 (TS-1) was synthesized using different crystallization temperature, aging time and aging temperature in order to get suitable nanoparticle size and good distribution of particle size for using them as a filler in MMMs.The TS-1 particles with different Si/Ti ratios were functionalized using different amino silane coupling agents: 3-aminopropyltriethoxysilane (APTES), 3-aminopropyltrimethoxysilane (APTMS) and 3-aminopropylmethyldiethoxysilane (APMDES). Moreover, a new kind of silane coupling agents: 3-glycidoxypropyltriethoxysilane (GPTES), 3-glycidoxypropyltrimethoxysilane (GPTMS) and 3-glycidoxymethyldiethoxysilane (GPMDES) were also used. Tetrahydrofuran (THF), with a high dielectric constant (7.6), was used as solvent in order to control the surface modification and avoid pore blockage.The samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Infrared spectroscopy (FTIR), as well as carbon dioxide methane and nitrogen adsorption measurements. Suitable TS-1 filler with good size distribution and particle size about 200nm was obtained using Si/Ti = 100 and Si/Ti = 25, Tc = 140°C, Taging = 40°C and taging = 7 days. Moreover, surface functionalization of TS-1 using THF as solvent showed a nearly net CO2 adsorption compared with unmodified TS-1. On the contrary, CH4 adsorption decreased significantly; therefore separation performance of TS-1 is improved with comparison to unmodified sample. The new kind of silane coupling agents (glycidoxy type) shows very promising results due to no-losses adsorption properties compared with unmodified particles. In conclusion, suitable nanoparticles TS-1 for MMM`s were developed and modification with glycidoxy silane coupling agents do not show significant adsorption properties losses.
