What is a monolith in chemistry?

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.

What is a catalyst substance?

Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.

What is the meaning of catalyst catalyst?

1 : a substance that enables a chemical reaction to proceed at a usually faster rate or under different conditions (as at a lower temperature) than otherwise possible. 2 : an agent that provokes or speeds significant change or action That waterway became the catalyst of the area’s industrialization.

How is a monolith used as a catalyst?

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.

What makes up the walls of a monolith?

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. Alternative structures include corrugated metal and a packed bed of coated pellets or other shapes.

Which is an example of a monolith reactor?

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.

What is the origin of the word monolith?

History and Etymology for monolith. French monolithe, from monolithe consisting of a single stone, from Latin monolithus, from Greek monolithos, from mon- + lithos stone.
