Production of C3+ Olefins and Propylene from Ethanol by Zr-Modified H-ZSM-5 Zeolite Catalysts

Advances in Materials Science and Engineering, 2012
Ethanol conversion to C3+ olefins, especially propylene, using Zr-modified H-ZSM-5 catalysts was investigated. Zr-modification to H-ZSM-5 zeolite could improve the initial yield of C3+ olefins and propylene and could reduce the initial yield of ethylene.

Ion Exchange of Na⁺ Ions with H⁺ Ions on ZSM-5 Zeolite Using Acetic Acid

Engineering Proceedings
ZSM-5 zeolites are primarily used in acid-catalyzed hydrocracking reactions in the petrochemical industry, and it is very important to ensure an adequate number of acidic sites for more efficient catalytic activity.

Synthesis and Magnetic and Optical Properties of Novel Fe@ZSM-5 Composites

Molecules
Alkaline treatment in 0.2 and 0.4 M NaOH solutions successfully generated controlled mesoporosity into ZSM-5 (Zeolite Socony Mobil-5) zeolite, resulting in average mesopore diameters of approximately 15 and 25 nm, respectively, while preserving the ...

The Role of Ethanol, Methyltriphenylphosphonium Bromide and Cetyltrimethylammonium Bromide as Directing Agents in Hydrothermal Synthesis of Aluminosilicate Molecular Sieve (ZSM-5) and Its Morphologies [PDF]

Journal of Sciences, Islamic Republic of Iran, 2004
Zeolite ZSM-5 presents a great source of interest in catalysis because of its shape selective properties. The absence of a relationship between the template size and shape of the structure generated during the synthesis of zeolites is illustrated by the ...
