Abstract
A tubular reactor having an insert for improving heat transfer characteristics of the tubular reactor. The insert comprises a catalyst and metal structures consecutively arranged in a lengthwise direction of the tube. The metal structures have radially expandable side walls and orifices for squeezing fluid between the metal structures and the tube wall. The radially expandable side walls form hollows between the radially expandable side walls and the tube wall of the tubular reactor. The radially expandable side walls deform responsive to the fluid pressure difference between the inside of the metal structure and the outer space between the metal structure and the tube wall thereby maintaining the gap between the orifice opening and the tube wall to adjust for tube creep.
