## Abstract

There is provided a radial flow reactor having a multi-pass structure in which loading and unloading of granular packing are easy and which does not impair the reaction performance. The reactor includes, in an upright tubular reactor vessel: a packing region for housing a continuous packed bed of granular packing; and an outer and an inner passages disposed outside and inside the packing region, respectively, allowing a fluid to flow in the axial direction. The reactor is configured so that the fluid can pass between the packing region and the outer passage and between the packing region and the inner passage.

## Claims

### Claim 1

A reactor comprising, in an upright disposed tubular reactor vessel:
a packing region which is a region for housing a continuous packed bed of granular packing; and
an outer passage and an inner passage disposed outside and inside the packing region, respectively, in a cross section perpendicular to the axial direction of the reactor vessel, each of the outer and inner passages allowing a fluid to flow therethrough in the axial direction,
the reactor being configured so that the fluid is able to pass between the packing region and the outer passage and the fluid is able to pass between the packing region and the inner passage, wherein
the reactor further comprises at least one of the partition structures from among:
an outer partition structure comprising: an outer partition plate which is a partition plate partitioning the packing region in the axial direction with a gap through which the granular packing is able to pass between an inner border of the packing region and said outer partition plate; and a blocking section for preventing the fluid from flowing through the outer passage in the axial direction; and
an inner partition structure comprising: an inner partition plate which is a partition plate partitioning the packing region in the axial direction with a gap through which the granular packing is able to pass between an outer border of the packing region and said inner partition plate; and a blocking section for preventing the fluid from flowing through the inner passage in the axial direction,
wherein in said at least one of the partition structures, the partition plate has an upward inclination toward a side having the gap.

### Claim 2 (depends on 1)

The reactor according to claim 1, wherein the inclination has an angle of from 15° to 50° .

### Claim 3 (depends on 1)

The reactor according to claim 1, wherein the angle of the inclination is equal to or greater than an angle of repose of the granular packing.

### Claim 4 (depends on 1)

The reactor according to claim 1, wherein at least one partition plate amongst the outer partition plate and inner partition plate is equipped with a tube for unloading the granular packing.

### Claim 5 (depends on 1)

The reactor according to claim 1, wherein the reactor comprises a heat transfer tube inside the packing region.

### Claim 6 (depends on 5)

The reactor according to claim 5, wherein the heat transfer tube is supported by at least one partition plate amongst the outer partition plate and inner partition plate.
