“…Methanol‐to‐aromatics (MTA) can serve as a bridge between the coal industry (supplying the feedstock methanol) and the petroleum industry, which is an important catalytic rote for China . Compared with the production of aromatics in petroleum industry, the MTA process using special ZSM‐5 catalyst can obtain nearly 100 % methanol conversion with over 90 % yield of aromatics …”

“…Since MTA is a heavily exothermic reaction (33 kJ/mol methanol) and the catalyst should be regenerated every 3–6 h due to its coke production, this process is recommended to be conducted in fluidized bed reactors . However, it is also a challenge for a single‐stage fluidized bed reactor, since deep conversion with favourable yield of intermediates like MTA requires plug‐flow conditions.…”

“…The multi‐stage fluidized bed is an efficient reactor, limiting back‐mixing of both the gas and solids phase, for the large‐scale production of aromatics at low cost. Recently, an industrial‐scale fluidized bed reaction system with the capability of 10 kt/y aromatics successfully running in China, as shown in Figure b and Table , has been a great breakthrough toward commercial production b are listed in Table .…”

The multi-stage fluidized bed (MSFB) reactor with several stages connected in series prevents gas and solids back-mixing effectively and obtains the plug-flow reactor performance. Besides, different process steps can be accomplished in a single reactor by establishing different temperatures and/or concentrations in each stage. Therefore, multi-stage fluidized bed reactors are acknowledged as novel and flexible multi-phase flow reactors for heterogeneous catalytic processes, especially with the intermediates as the desired products. Typical process developments in the industry involve the methanol to aromatics (MTA), regeneration in fluid catalytic cracking (FCC), and hydrogenation of nitrobenzene to aniline. The purpose of this article is to provide a comprehensive review of the fundamental research as well as particular industrial applications on multi-stage fluidized bed reactors in the Fluidization Laboratory of Tsinghua University (FLOTU).

“…Methanol to hydrocarbons (MTHC) is an important route for connecting coal or natural gas industry (supply the feedstock methanol) to petroleum industry (Su et al, 2015). Methanol can be produced from biomass that is renewable and abundant, also via synthesis gas through gasification of coal or steam reforming of natural gas, and further converted to hydrocarbons (Yang et al, 2011).…”

Precise product distribution data is very important for kinetic modeling of chemical reactions and chemical reactor design. In this work, H-ZSM-5 catalyst was hydrothermally synthesized and characterization tests including XRD, XRF, BET, and NH 3 -TPD revealed its physicochemical properties. Then, methanol conversion into hydrocarbons over ZSM-5 was investigated with WHSV of 4 h −1 at reaction temperature 410°C. Product distribution result indicated that C 3 -C 5 + and C 2 = -C 4 = were the major products in gaseous phase, and in liquid phase xylenes, three methyl benzene and C 10 + aromatics were the main components. It was also observed that the synthesized ZSM-5 had good performance in the methanol to hydrocarbons process and gave rise to highest activity (100%) during 10 h of operation approximately.

Catalytic performance is influenced by the morphology and assembly of catalyst particles. Therefore, Zn ion‐doped HZSM‐5 zeolite with different morphological structures is prepared using post‐treatments of selective dissolution and recrystallization, causing silicon components to migrate from the interior to the exterior in the different template etching processes. The core–shell, hollow, and hierarchical core–shell Zn/HZSM‐5 microspheres with weak acid sites on the external surfaces are successfully synthesized. Hierarchical core–shell‐structured Zn/HZSM‐5 microspheres with a silicon‐rich surface layer are prepared using an etching method in n‐butylamine solution. Their catalytic activity is investigated in methanol aromatization. The functionalized morphological Zn/HZSM‐5 catalysts show good catalytic performance and the silicon‐rich surface layer improves selectivity of p‐xylene in the reaction of methanol to aromatics.
