## Abstract

A catalyst carrier for insertion in a reactor tube of a tubular reactor, said catalyst carrier comprising: a container for holding catalyst in use, said container having a bottom surface closing the container, and a top surface; a carrier outer wall extending from the bottom surface to the top surface; a seal extending from the container by a distance which extends beyond the carrier outer wall; said carrier outer wall having apertures located below the seal.

## Claims

### Claim 1

A catalyst carrier for insertion in a reactor tube of a tubular reactor, said catalyst carrier comprising:
a container for holding a monolith catalyst in use, said container having a bottom surface closing the container, and a top surface;
a carrier outer wall extending from the bottom surface to the top surface;
a seal extending from the container by a distance which extends beyond the carrier outer wall;
said carrier outer wall having apertures located below the seal.

### Claim 2 (depends on 1)

The catalyst carrier according to claim 1 comprising feet on the bottom surface such that, in use, the monolith catalyst is supported on the feet and there is a gap between the bottom of the monolith catalyst and the bottom surface of the container.

### Claim 3 (depends on 1)

The catalyst carrier according to claim 1 wherein the top surface is an annulus which extends over at least a portion of the monolith catalyst and to the carrier outer wall.

### Claim 4 (depends on 1)

The catalyst carrier according to claim 1 wherein the monolith catalyst has a channel extending longitudinally therethrough.

### Claim 5 (depends on 4)

The catalyst carrier according to claim 4, wherein the channel is located on a central axis of the monolith catalyst such that the monolith catalyst is of annular cross-section.

### Claim 6 (depends on 4)

The catalyst carrier according to claim 4, wherein the top surface extends over the monolith catalyst but leaves the channel uncovered.

### Claim 7 (depends on 1)

The catalyst carrier according to claim 1 wherein the carrier outer wall is smooth or shaped.

### Claim 8 (depends on 1)

The catalyst carrier according to claim 1 wherein the apertures in the carrier outer wall are slots.

### Claim 9 (depends on 1)

The catalyst carrier according to claim 1 wherein carrier outer wall material is left partially attached to the carrier outer wall when the apertures are formed.

### Claim 10 (depends on 9)

The catalyst carrier according to claim 9 wherein the attached material is configured to induce direction for the fluid flow.

### Claim 11 (depends on 1)

The catalyst carrier according to claim 1 additionally including the monolith catalyst.

### Claim 12 (depends on 11)

A reactor tube comprising a plurality of catalyst carriers according to claim 11.

### Claim 13 (depends on 12)

A reactor including one or more reactor tubes according to claim 12.

### Claim 14 (depends on 11)

A process for carrying out a reaction comprising introducing reactants into a catalyst carrier according to claim 11.

### Claim 15 (depends on 12)

A process for carrying out a reaction comprising introducing reactants into a reactor tube of claim 12.

### Claim 16 (depends on 13)

A process for carrying out a reaction comprising introducing reactants into a reactor of claim 13.
