Embodiment Construction

[0009] The reactor will be described in detail below:

[0010] figure 1 Drawings showing particular embodiments and different components of the invention. The reactor is upflow and has an inlet (1) present on the bottom of the reactor through which a gaseous feed stream containing particles enters. Guide vanes (8) may be present at the inlet and within the reactor to direct the gas in the direction of the catalytic bed. However, they are not essential for the presence of the reactor of the invention, and thus their presence is optional.

[0011] The reactor comprises a catalytic unit and the figure shows a reactor with two catalytic beds. After passing the guide vanes (8), the particle-laden gas is guided through a dust rectifier (2) towards the catalytic bed (3). The dust rectifier (2) regulates the path of solid dust particles in the gas before entering the catalytic bed (3). After passing through the catalytic bed (3), the gas containing part of the particles enters th...

Abstract

The invention concerns an up-flow reactor for catalytic treatment of a particle-containing gas comprising a catalytic unit and at least one drain pipe upstream the catalytic unit within a reactor wall.

Description

technical field [0001] The present invention relates to a reactor for the catalytic treatment of gases containing particles, and in particular the invention relates to an upflow catalytic reactor suitable for removing particles. Background technique [0002] The presence of particles in the gas in a catalytic reactor presents many problems. Particles such as dust cause corrosion and fouling of the catalytic bed. In reactors using an upflow system, large amounts of dust are deposited on the catalytic bed and lead to blockage of the channels in the bed. Contents of the invention [0003] It is therefore an object of the present invention to provide a catalytic reactor capable of removing particles present in the gas entering the reactor. [0004] This is achieved by the present invention, which provides an upflow reactor for the catalytic treatment of a gas containing particles, the reactor comprising a catalytic unit and at least one discharge pipe upstream of the catalyt...
