Synthesis and Characterization of Beta/MCM-41 Composite Zeolite and its Performance for n-Butane Adsorption
A series of beta/MCM-41 composites with different molar ratios of microporous template agent (tetraethylammonium hydroxide or TEAOH) to mesoporous template agent (cetyltrimethylammonium bromide or CTAB) was synthesized using a two-step method. Results of X-ray powder diffraction, scanning electron m...

| description | A series of beta/MCM-41 composites with different molar ratios of microporous template agent (tetraethylammonium hydroxide or TEAOH) to mesoporous template agent (cetyltrimethylammonium bromide or CTAB) was synthesized using a two-step method. Results of X-ray powder diffraction, scanning electron microscopy and N 2 adsorption confirmed that a proper molar ratio of TEAOH to CTAB benefit the formation of composite structures. The measurements of adsorption of n-butane onto the as-synthesized composites were performed at 308 K. All the experimental data fitted well with the Langmuir model. The results of n-butane adsorption demonstrated that the specific surface area and micropore volume played important roles in determining the adsorption capacity of the composites. The isosteric heat of n-butane adsorption at different coverage was also calculated using Clausius–Clapeyron equation. |
