A tube reactor for heterogeneous catalyzed gas phase reactions having a thermal tube with a catalyst material around which a fluid heat transfer medium, a temperature-sensitive optical waveguide surrounded by a capillary tube that extends into the catalyst material and has measuring points having a predetermined spacing between adjacent measurement points, and can be connected to a source for optical signals and to an evaluation unit () for optical signals reflected by the optical waveguide. The optical waveguide has measuring points having a spacing between adjacent measuring points in the axial direction of the thermal tube which is 0.8 to 5 times the shortest edge length of all imaginary cuboids which, having a minimum volume in the cases in which nominal external dimensions are associated with particles of the catalyst material.

Fibre-obtic temperature measurement in a catalyst material

A tube bundle reactor for carrying out catalytic gas phase reactions, particularly methanation reactions, has a bundle of catalyst-filled reaction tubes through which reaction gas flows and around which heat carrier flows during operation. In the region of the catalyst filling, the reaction tubes run through at least two heat carrier zones which are separated from one another, the first of which heat carrier zones extends over the starting region of the catalyst filling. The reaction tubes each have a first reaction tube portion with a first hydraulic diameter of the catalyst filling and, downstream thereof in flow direction of the reaction gas, at least a second reaction tube portion with a second hydraulic diameter of the catalyst filling that is greater than the first hydraulic diameter of the catalyst filling.

Shell-and-tube reactor for carrying out catalytic gas phase reactions

A method for carrying out endothermic or exothermic gas phase reactions by using a tube bundle reactor with a tube bundle of catalyst-filled reaction tubes comprises the following steps:
