“…More details of this preparation process have been provided by Li et al [170] and Aranzabal et al [171]. In the preparation of these extruded monoliths, the added binder can be problematic, as it can block the pores of the zeolite [172][173][174]. Pulsed current processing has been suggested to overcome this problem by making use of a high heating rate and compressive pressure, which can yield a porous structure with good mechanical strength (without a binder) [175][176][177].…”

Considerable research has been conducted on monolithic catalysts for various applications. Strategies toward coating monoliths are of equal interest and importance. In this paper, the preparation of monoliths and monolithic catalysts have been summarized. More specifically, a brief explanation for the manufacturing of ceramic and metallic monoliths has been provided. Also, different methods for coating γ-alumina, as a secondary support, are included. Techniques used to deposit metal-based species, zeolites and carbon onto monoliths are discussed. Furthermore, monoliths extruded with metal oxides, zeolites and carbon are described. The main foci are on the reasoning and understanding behind the preparation of monolithic catalysts. Ideas and concerns are also contributed to encourage better approaches when designing these catalysts. More importantly, the relevance of monolithic structures to reactions, such as the selective oxidation of alkanes, catalytic combustion for power generation and the preferential oxidation of carbon monoxide, has been described.

“…The extrusion process is the most reliable method for shaping Raschig rings [11]. The inorganic binders used in shaping zeolite-based adsorbents are generally bentonite and kaolin with very low iron oxide content, which is essential to develop plastic forming and provide the desirable mechanical strength for both of green and dry specimens [12]. Some organic binders such as polyvinyl alcohol, carboxymethyl cellulose and Arabic gum may also be used in the composition of Raschig rings [13].…”

“…In a similar way, there are many studies in which clays, although part of a structured support, are not the majority component but mere binders to shape other materials into ceramic bodies. The list of these materials is long and includes carbon, mainly activated [13,14] but also in the form of coals [15], carbon black [16] and even carbon fibres [17], TiO 2 [18][19][20][21], Al 2 O 3 [18,22], zeolites [23,24], mullite [25], SiC [26], Al 2 O 3 -SiO 2 [19,27], ZrSiO 4 [28], FeTiO 3 [29], B 2 O 3 [30], Fe 2 O 3 -Cr 2 O 3 [31], Al 2 TiO 5 [32], LiAlSi 4 O 10 [33], etc.…”
