Abstract: A support structure for a structured catalytic packing is disclosed. The support structure is in a fixed position relative to the reactor tube containing it. It supports catalyzed casings that are free to move relative to the support structure. The support structure and casings are inserted in the reactor tube such that the support structure is located proximate the longitudinal axis of the tube and the casings are located between the support structure and the reactor tube wall. The support structure comprises a central support tube or rod proximate to, and impervious or perforated discs perpendicular to, the longitudinal axis of the reactor tube, and may comprise spacers separating the discs.

Abstract: High purity hydrogen is produced by a steam reforming hydrogen production unit with at least one of a bayonet reactor for reforming steam and a hydrocarbon, a recuperative burner, and a regenerative burner such that the steam reforming unit produces little or no steam in excess of the steam reforming process requirements. High purity hydrogen is separated from the syngas exiting the reformer via a pressure swing adsorption unit and combined with high purity nitrogen from an air separation unit as feedstock to a Haber process ammonia synthesis unit. Compressors for the ammonia synthesis unit are driven by higher efficiency drivers than are possible using the low temperature steam conventionally exported from a steam reforming unit. Compression power requirements are reduced.

Abstract: A structured packing for insertion in a reactor having an inlet, an outlet, a wall and an axis. The packing comprises a first part, i.e., a reactor core and a second part, i.e., a reactor casing. The second part is free to move relative to the first part. The first part and the second part are inserted in the reactor such that the first part is located proximate the axis and the second part is located between the first part and the reactor wall. In general, the second part will be in contact with the reactor wall.
