Abstract
Conduits for a radial flow reactor to provide fluid/solid contacting are improved structurally in terms of possessing good flexibility and a high resistance to vertical buckling when subjected to radially and axially directed stresses. The desired conduit characteristics are obtained using connection flaps to flexibly join a curved profile wire front side to a flatter back side that is proximate to the reactor vessel wall. The rigid profile wire section is maintained at some distance from the vessel wall so that the conduit can flex without permanent damage in an environment where stresses are imparted due to either temperature or thermal expansion differences within the reactor environment. The radial flow reactor of this invention is especially suited for processes such as catalytic reforming where thermally-induced stresses result from both transient and discontinuous operation.
