“…This result implies that some Al species from the pseudo-boehmite binder might migrate into the mordenite framework during calcination. Similar results have been reported by Fougerit et al [25] and Zhang et al [14]. Moreover, Al(VI) sites are also increased with the continuous addition of pseudo-boehmite binder.…”

The influence of pseudo-boehmite binder on the catalytic properties of dealuminated mordenite (MOR) catalyst for Friedel-Crafts alkylation was investigated. Solidstate 27 Al MAS NMR spectroscopy, temperature-programmed desorption of ammonia (NH 3 -TPD), BET surface area measurement and catalyst particle mechanical strength were used to characterize the catalysts. It was observed that the addition of pseudo-boehmite binder results in improvement in terms of pore size distribution and its mechanical strength. Furthermore, the dredged pore path of MOR was not destroyed although the acid amount and acid type were adjusted properly when the modified MOR was calcinated. Among these catalysts studied, the catalyst bound with 10 wt% pseudo-boehmite binder showed the best catalytic performance in terms of yield and stability, which can be attributed to its maximum medium strong acid amount and its structural properties which is favorable for fast diffusion of products.

“…Whiting et al (36) used microspectroscopy to show aluminium migration in ZSM-5-containing Al2O3-bound extrudates, forming additional Brønsted acid sites. Fougerit et al (37) attributed the increase in the stability of a dealuminated mordenite catalyst for methanol to olefin conversion to the trapping of coke precursors in the binder phase. Shihabi et al (38) showed that an α-alumina monohydrate binder inclusion on a siliceous H-ZSM-5 catalyst significantly enhanced the conversion of methanol to hydrocarbons.…”

“…A second effect may be introduced by the chemical nature of these binders. Especially at high temperatures, common binder materials such as silica, alumina or clay may exhibit catalytic effects which can influence the intended chemical nature of the catalyst (Fougerit et al, 1994;Choudhary et al, 1999;Jasra et al, 2003;Hargreaves and Munnoch, 2013;Bingre et al, 2018;Shen et al, 2019;Vajglová et al, 2019). Considering potentially adverse binder effects and determining the right balance, amount and type of inorganic and organic additives is an essential part of all shaping methods, both for conventional and 3D-printing techniques.…”

Additive manufacturing of catalyst and sorbent materials promises to unlock large design freedom in the structuring of these materials, and could be used to locally tune porosity, shape and resulting parameters throughout the reactor along both the axial and transverse coordinates. This contrasts catalyst structuring by conventional methods, which yields either very dense randomly packed beds or very open cellular structures. Different 3D-printing processes for catalytic and sorbent materials exist, and the selection of an appropriate process, taking into account compatible materials, porosity and resolution, may indeed enable unbounded options for geometries. In this review, recent efforts in the field of 3D-printing of catalyst and sorbent materials are discussed. It will be argued that these efforts, whilst promising, do not yet exploit the full potential of the technology, since most studies considered small structures that are very similar to structures that can be produced through conventional methods. In addition, these studies are mostly motivated by chemical and material considerations within the printing process, without explicitly striving for process intensification. To enable value-added application of 3D-printing in the chemical process industries, three crucial requirements for increased process intensification potential will be set out: i) the production of mechanically stable structures without binders; ii) the introduction of local variations throughout the structure; and iii) the use of multiple materials within one printed structure.
