The stackable structural reactor (SSR) from Catacel Corporation is a direct replacement for the loose ceramic catalyst media traditionally used in the stationary steam-reforming process by industrial plants to produce hydrogen from natural gas. The heat transfer increase gained from advanced SSR catalyst technology can enable an approximate 25% throughput improvement from most reformers to create significant energy and capital savings in hydrogen production as well as fuel cell, biofuel, alternative energy and solid/gas-to-liquid applications.
