Abstract

1,223,001. Porous refractories. SHIKISHIMA MUL-BII K.K. 16 Feb., 1968, No. 7781/68. Heading C1J. [Also in Divisions B1 and C2] A sintered porous catalyst carrier comprises an aggregated inorganic material interconnected by a sintered inorganic bonding material and having a microporous structure comprising voids of size distribution such that a graph of the radius of the void against the cumulative volume of all voids having equal and greater radii is of step-like form and comprises at least 2 steps. Suitable aggreagated inorganic materials are fused alumina, silicon carbide and zircon and suitable bonding materials are fusible clay and porcelain clay. The carrier can be shaped as cylinders, truncated cones, discs, annulii, hollow cylinders, spheres or a shell surrounding an impermeable core of porcelain clay, bauxite and/or mullite. The catalyst carrier is made by (1) forming bonding granules from a pulverulent inorganic material and an inorganic bonding material and coating the bonding granules with an organic surface forming material; (2) mixing the coated bonding granules with pulverulent inorganic aggregate material, pulverized organic void forming material of predetermined size and inorganic bonding material to form aggregate grains; (3) mixing the aggregate grains with pulverized organic void forming material of particle size different from that of the void forming material used in step (2) and inorganic bonding material to form carrier pellets; and (4) sintering the pellets at 1000-1400‹ F. thereby to convert the organic surface and void forming materials to gaseous substances and to form voids in the pellets. Step (2) can be used to make several batches of aggregate grains, each batch using a void forming material of different particle size so that more steps are formed on the graph. Suitable void forming materials are walnut shell, Indian corn core, cotton yarn waste, woden scobs and styrene resins. In an example the surface and void forming materials used in steps (1), (2) and (3) have increasing sizes.
