Structure useful for heat- and/or mass transfer for catalytic material, comprises structure panel comprising two layers with different thermal expansion coefficient, and central, tubular or rod-shaped mounting element

摘要

Structure (20) comprises at least one structure panel (22) comprising at least two layers (24, 26) with different thermal expansion coefficient. The structure panel is arcuately arranged around a central, tubular or rod-shaped mounting element (40). Independent claims are also included for: (1) a reactor (10) comprising at least one tube and the structure, which is arranged in the tube, where the structure panel is modified through rotation of the mounting element around its longitudinal axis in its spatial form; (2) fixing the structure in the tube of the reactor comprising inserting the structure into the tube and pressing against the tube by heating, cooling and/or rotating around its longitudinal axis; and (3) catalyzing a reaction comprising using the structure and/or the reactor.
