Monolith (catalyst support) - Wikipedia
网页The monolith is a substrate that supports a catalyst. After the monolith is complete, a washcoat is applied that deposits oxides and catalyst (s) (most commonly platinum, palladium, and/or rhodium) on the walls of the holes.

网页Monolithic catalysts show a promising future in oxidation catalysis. Noteworthy is the dearth of literature on the application of monolith catalysts in the partial oxidation of medium chain length linear alkanes, which have low value, yet high abundance. The vast majority of reports have focused on methane to propane.
Monolithic Catalysts and Reactors: High Precision with Low …
网页2011年1月1日 · Heterogeneous catalysis plays a key role, and in most cases structured reactors, in particular monoliths, outperform packed beds because of (i) low-pressure drop, (ii) flexibility in design for fast reactions (thin catalytic layers with high GSAs are optimal), and (iii) high attrition resistance (136).
Revolutionizing Monolithic Catalysts: The Breakthroughs of …
网页Catalysts probed to have excellent activity in the different reactions: the mixed metal oxides monolith produced ≈40% propane conversion, ≈50% CO 2 conversion, and 91% propylene selectivity; Cr-doped catalyst led to 85% n-hexane conversion with high selectivity to olefins and no BTX production; and Ga 2 O 3 doped catalyst produced great ...

Preparation of monolithic catalysts - Taylor & Francis Online
网页2007年2月3日 · Monolithic catalysts can be attractive replacements for conventional catalysts in randomly packed beds or slurry reactors. The conventional procedures for preparing catalysts, however, cannot simply be applied to monolithic catalysts. Different procedures are discussed on how to put a coat layer of a …
Monolithic Catalysts and Reactors: High Precision with Low …
网页2011年1月1日 · Monoliths offer freedom in the design of reactor configuration. Examples are loop reactors for strong exo- and endothermic reactions, which allow a combination with separate heat exchange without the penalty of a large energy consumption, which otherwise is usually unavoidable for the large recycle ratios needed.
