A bed packing material, e.g. for use as a catalyst precursor, in the form of regular, preferably cylindrical, units having a multiplicity of through passages of small cross section so that the units have a low voidage, GV, a high ratio of the geometric surface area, GSA, to the volume V, of the equivalent cylindrical unit having no passages, and a high ratio of GSA to the product of GV and the surface area, A, of the equivalent cylindrical unit having no passages.
