Packing member
A packing member for use in a packed bed, wherein the packing member comprises ceramic material and further comprises surface structures on its outer surface, and wherein the packing member does not comprise a fluid communication intra-particle channel extending through the packing member from a first aperture on a first side of the packing member to a second aperture on a substantially opposing second side of the packing member. The packing member may have a multi-lobe macrostructure with a largest dimension of >20mm and can comprise a plurality of repeating surface structures e.g. interconnected ridges and/or troughs, extending over ≥20% of the outer surface. Preferably, the packing member has a geometric surface area per volume (GSA) of ≥0.7cm2/cm3, a side crush strength of ≥70kgf, and a porosity of 0.06-0.5 cm3/g. The packing member can be obtained by gel casting. Also described is a supported catalyst, a method for producing the packing member and supported catalyst, a catalyst bed reactor and reaction medium, and uses of the packing member and/or supported catalyst as an absorber for contaminant removal, in the production of synthesis gas or direct reduced iron (DRI), in endothermic gas generation, in catalytic partial oxidation, and in autothermal reforming.
