Organic-free modulation of the framework Al distribution in ZSM-5 zeolite by magnesium participated synthesis and its impact on the catalytic cracking reaction of alkanes

Regulation of the Si/Al ratios and Al distributions of zeolites and their impact on properties

“… 28 Recently, Shen and co-workers reported that introducing Mg into the framework of ZSM-5 results in a slight increase in the amount of Al pairs in both the straight channel (from 5% to 10%) and the sinusoidal channel (from 16% to 22%). 270 …”

Alumina binder effects on the hydrothermal stability of shaped zeolite-based catalyst bodies

“…1d, in which the peak at 1445 cm −1 can be assigned to LASs and 1545 cm −1 to BASs. 39–41 Prior to steaming, the acidity of the zeolite powder sample is governed by BASs, while the catalyst extrudate appears with a higher amount of LASs. As aforementioned, LASs in the catalyst extrudates can be attributed to the presence of the alumina binder.…”

Effect of Steaming on Waste‐Derived Zeolite ZSM‐5 as Methanol‐To‐Hydrocarbons Catalyst

“…The peaks at 1453 cm À 1 and 1545 cm À 1 are assigned to LAS and BAS, respectively. [52][53][54] The commercial zeolite sample upon steaming showed a strong decrease in the number of BAS as well as a slight decrease in the number of LAS. Regarding the waste-derived zeolite ZSM-5 materials, especially, sample S3 showed the same trend as the commercial sample.…”
