A reactor system comprising a first reactor assembly, a first pressure transition assembly, a second reactor assembly and a second pressure transition assembly.

The invention relates to a filling device (1) for filling a container with a particulate material (28). The filling device (1) comprises a supply container (2) that can be filled with the particulate material (28), wherein the supply container (2) has a lower opening (2.2). Moreover, the filling device (1) comprises a radial distribution unit (3), which can be supplied with the particulate material via the lower opening (2.2) of the supply container (2) and which is connected to the supply container (2) in such a way that it can rotate about a rotational axis (A), in order to distribute in the container the particulate material (28) supplied from the supply container (2) to the distribution unit (3). The filling device is characterized in that the distribution unit (3) can be driven by a drive unit (4) that is arranged outside the supply container (2).

Provided herein are methods for effectively loading reactor material into fixed bed reactors. The subject methods and systems for loading catalyst particles and inert particles onto a reactor bed utilize a novel sock having a helical-shape that can restrict reactor material traveling through the elevation of the fixed bed reactor to the reactor bed and avoid damaging the reactor material upon impact. The sock comprises a cylindrical tube having a plurality of helixes. Each helix of the cylindrical tube has a downward slope. The downward slope of each helix exceeds an angle of repose of the reactor material. The present methods and system are particularly effective for improving the performance of reactor bed configurations of vertically-oriented fixed bed reactors and flow distribution through the bed at designated operating conditions.

A method of installing a temperature measuring device inside a reactor tube while filling the tube with catalyst is provided. The method includes inserting a positioning system, including multiple inflatable bladders connected at a central location to a centering ring, into reactor tube, the reactor tube comprising a distal end and a proximal end. Then inserting a temperature measurement device into the centering ring. Locating the positioning system at a first predetermined distance from the distal end. Then inflating the multiple inflatable bladders, thereby centering the centering ring and the temperature measurement device within the SMR tube, and introducing catalyst into the SMR tube, thereby enclosing the temperature measurement device in catalyst.

A device for centering a temperature measurement device inside a tube reactor that will be filled with catalyst, including a single inflatable bladder mechanically and fluidically attached to a centering ring.
