The support ring provides structural support to the catalyst bed grid system, distributing mechanical loads from the catalyst weight and process pressure while maintaining proper gas flow distribution through the catalyst bed.
High-temperature alloy steels like ASTM A387 Grade 11/22, stainless steels (AISI 321/347), or nickel alloys (Inconel) are used depending on operating conditions, with selection based on temperature resistance, pressure capability, and corrosion resistance in hydrogen-rich environments.
Proper support ring design ensures uniform load distribution, prevents catalyst particle migration, maintains bed stability during thermal cycling, and enables optimal gas flow patterns for maximum ammonia conversion efficiency.
