“…Characteristic peaks of T-type zeolite using bamboo leaves as silica source are similar with Ttype zeolite that is synthesized using commercial silica source [1][2][3]. The result of XRD analysis shows that the formed T-type zeolite is close to zeolite erionite type standard [3]. Erionite is a type of zeolite that is formed from hexagonal units that are not connected to six-ring plane.…”

“…From figure 5, it can be concluded that the particles have uniform size and cylindrical column shape [1][2][3]. Based on observations using the imageJ application, the particle size shown in the photo of the SEM results has the smallest particle size is 26 nm and 218 nm being the largest, with the average particle size size is 133.25 nm.…”

“…Then the absorption band of 563 cm -1 is the secondary building unit of single ring in T-type zeolite structure and at the wave number 663 cm -1 is the T-O-T vibrational bond. Then the wavelength of 723 cm -1 is the vibration of the double ring symmetry vibration, at the wave number 800 cm -1 is Si-O-T bond and at 1,150 cm -1 asymmetry of double ring bending bands which is Si-O and Al-O bonds [3]. fig.…”

“…The method used by Yin et al [2] become the reference in the synthesis process of this Ttype zeolite. In hydrothermal method ,the temperature is one of the factors affecting the level of crystallinity of Ttype zeolite, when the temperature increases so does the level of crystallinity forming the characteristic of T-type zeolite [3,10]. The identification of functional groups in synthesized T-type zeolite ( fig.…”

“…Zeolites are crystalline hydrated aluminosilicate minerals containing alkaline or alkaline earth cations within its three-dimensional framework. Until now, there are many known types of zeolite structure that have been successfully synthesized, and among them is T-type zeolite [1][2][3]. T-type zeolite is widely used for several separation processes such as the separation of CO2/CH4 and CO2/N2 mixtures [4], the separation of water/organic liquid mixtures [5], the pervaporation-aided esterification of acetic acid with ethanol [6], etc.…”

The increased use value of bamboo leaves as silica source for t-type zeolite synthesis

T-type zeolite can be used as catalyst, adsorbent, and membranes for gas separation. The synthesis of T-type zeolite needs to be optimized in both of the method and source of precursor, because of its relatively high price. In this research, the synthesis is done using silica extracted from bamboo leaves instead of commercial silica. This increases the value of the bamboo leaves and the cost-performance of zeolite synthesis. The silica was extracted from bamboo leaves ash using alkaline solvent. The extracted silica has 81.76% of purity and an amorphous phase. The T-type zeolite was synthesized using the molar composition of 0.15 Na2O : 0.025 Al : 0.15 K2O : 1 SiO2 : 15 H2O : 0.06 TMAOH, under hydrothermal method and heating process for 4 days, 60°C for 2 days and 120°C for the next 2 days. The characterization method using X-Ray Diffraction and Infra-Red Spectroscopy were performed to confirm the formation of T-type zeolite. The results of Scanning Electron Microscope (SEM) analysis show that the formed T-type zeolite has erionite cylindrical crystal shape.

Natural gas consisting mainly of methane is becoming increasingly prominent as a clean energy source. However, the major impurity, carbon dioxide, can adversely affect the performance of natural gas. Therefore, separating CO2 from CH4 is necessary to decrease the erosion of pipelines and increase the calorific value. This paper aimed at reviewing the performances, mechanisms, and novel developments of common adsorbents to adsorb pure CH4, pure CO2, and their mixtures. Several studies suggest that zeolites exhibit better separating performance than metal organic frameworks (MOFs) except the modified amine‐MIL group. Activated carbons may not be suitable adsorbents due to low selectivity between CO2 and CH4. The modified amine‐MIL group are the best type of adsorbent to separate CO2 from CH4 and its best operating conditions are at low pressure (<2 bar), low feed composition of CO2, and near room temperature using pressure swing adsorption (PSA) method.
