Characterization of Ghanaian clays as raw materials for the synthesis of ZSM-5 zeolite

open access: yesScientific African
Clay minerals are inexpensive and widely available starting materials for the synthesis of zeolites, such as ZSM-5. In this work, clay samples were collected from Anfoega, Mfensi, Teleku-Bokazo, and Tetebu clay reserves in Ghana and used as sources of ...

Esterification process catalyzed by ZSM-5 zeolite synthesized via modified hydrothermal method

open access: yesMethodsX, 2018
A modified hydrothermal method for ZSM-5 synthesis was described. The crystals gave a typical pattern (2θ at around 22.5°, 24.0° and 29.8° corresponding to the major peaks of (501, 303 and 503 crystal surfaces)), which indicated that the subnanocrystals ...

Synergistic effects of Ni and CeO2 on ZSM-5 for enhancement of CO2 methanation at low temperatures

open access: yesSustainable Chemistry for Climate Action
Methanation offers a potential option for converting CO2 to green synthetic fuels, providing a solution for reducing carbon emissions. Nickel-based catalysts, promoted with CeO2 and supported on zeolite ZSM-5, were synthesized for CO2 methanation using ...

Synthesis of Dimethyl Terephthalate from Terephthalic Acid Esterification over the Zeolite Catalysts

open access: yesInorganics
The esterification of terephthalic acid (PTA) with methanol to dimethyl terephthalate (DMT) was investigated using commercially available zeolite catalysts as the eco-friendly solid acids. Six typical zeolites (ZSM-5-25, ZSM-5-50, ZSM-5-100, ZSM-35, MOR,

Hierarchical MnOx/ZSM-5 as Heterogeneous Catalysts in Conversion of Delignified Rice Husk to Levulinic Acid

open access: yesIndonesian Journal of Chemistry, 2019
Hierarchical ZSM-5 zeolite was synthesized using a double template method using TPAOH and PDDA as templates, while microporous ZSM-5 was also prepared using only TPAOH as a template. The syntheses then were followed by impregnation with Mn(II) c.a. 2 wt.%

The Surface-to-volume Ratio of the Synthesis Reactor Vessel Governing the Low Temperature Crystallization of ZSM-5

open access: yesJournal of Mathematical and Fundamental Sciences, 2016
Zeolite ZSM-5 is one of major catalysts in petroleum and fine-chemical industries. The synthesis of zeolite ZSM-5 is usually carried out at high temperature above 100 °C using the immense amount of organic structure-directing agents (OSDA).

Use of chitin as a template for the preparation of mesostructured ZSM-5

open access: yesCerâmica
In this work, mesostructured ZSM-5 zeolite was prepared using chitin as a new template to produce mesoporosity. Different amounts of chitin were used for the synthesis of ZSM-5 in order to verify its influence on the formation of mesopores.
