FIELD: catalysts.

SUBSTANCE: ceramic catalyst supports and supported catalysts intended for use in processes such as steam reforming and production of direct reduced iron. A packing element is presented for use in a packing layer, wherein the packing element comprises a ceramic material, and wherein the packing element has a geometric surface area per volume≥ 0.7 cm²/cm³ and side crush strength≥ 250 kgf; or geometric surface area per volume≥ 1.5 cm²/cm³ and side crush strength≥ 150 kgf; or geometric surface area per volume≥ 3 cm²/cm³ and side crush strength≥ 60 kgf, as well as a packing element for use in the packing layer, while the packing element is obtained by casting a gel from a composition containing a ceramic material and an organic binder, and the packing element has a macrostructure and surface structures on the outer surface of the macrostructure, and the surface structures are on at least 60% of the outer surface of the macrostructure. In another embodiment, a method for making a packing element is provided, comprising the steps of: bringing the packing element composition into contact with a polymerization initiator; placing the composition obtained in step (a) into a mold; removing the composition from the mold to obtain a raw workpiece; burn the raw workpiece. Also a reactor is presented with a catalyst layer, wherein the catalyst layer contains a packed element and/or a supported catalyst, and a method for producing synthesis gas such as ammonia, methanol, hydrogen, hydrogen peroxide and/or oxoalcohols, or for producing direct reduced iron, or endothermic gas production, or catalytic partial oxidation, or autothermal reforming, including the use of a reactor with a catalyst layer, while the catalyst layer contains a packed element and/or a catalyst on a substrate.

EFFECT: providing a packed element intended for use as a catalyst support in a reactor with a packed layer, wherein the packed element includes a ceramic material, and the packed element is characterized by an increased geometric surface area and increased lateral crush strength and porosity.
