Atomic Layer Deposition of Zinc Oxide on HZSM-5 Template and Its Methanol Aromatization Performance

Synthesis of Ga2O3/HZSM-5@cubic ordered mesoporous SiO2 with template Pluronic F127 to improve its catalytic performance in the aromatization of methanol

“…Generally, benzene (B), toluene (T) and xylene (X) are known as important chemical raw materials, they are often synthesized by the catalytic reforming of naphtha [1]. At the same time, methanol, as a common and cheap organic material, to be an another important raw material to the production of BTX, due to the continuously price rising of the oil price and increasing consumption of aromatics [2]. HZSM-5 is often selected and regarded as a promising catalyst in methanol to aromatics (MTA) for its acidity, high thermal stability, large surface area and adjustable pore size comparable to the molecular dimension of BTX [3].…”

Selective Production of Benzene, Toluene and p‐Xylene (BTpX) from Various C1‐3 Feedstocks over ZSM‐5/Silicalite‐1 Core‐Shell Zeolite Catalyst

“…Alkylation and disproportionation of toluene are another route to produce xylenes. So far, zeolite catalysts for BTX synthesis from C 1‐3 feedstocks like methanol (MeOH), dimethyl ether (DME), ethanol (EtOH), acetone and so on have been widely studied . However, separation of p ‐xylene from other isomers is a serious issue because the difference in boiling points between them is too small to separate them by distillation.…”

Biomass‐Derived Renewable Aromatics: Selective Routes and Outlook for p‐Xylene Commercialisation

“…Both MTG and MTA, but especially MTA, research has mainly focused on modified MFI‐type catalysts . Investigations on modifying the zeolite with metal oxides such as Cu, Ni, Ag,, Ga, or Zn, agree that addition of these oxides provides further acid or basic sites to the zeolite materials resulting in increased activity and selectivity towards the aromatic products. For example, Inoue et al .…”
