Saint-Gobain produces dense and insulating bricks, dense and insulating castables, brick linings and special bricks for secondary reforming applications in the production and conversion of syngas into products e.g., nitrate derivatives, methanol or liquid fuels.
High-purity, high-density alumina and zirconia materials offer excellent erosion and chemical resistance properties. Coupled with unparalleled engineering expertise, Saint-Gobain can manufacture all required brick shapes and configuration, including manholes, junctions, domes and diffusers. Production accuracy and excellent quality allows best fitting and fast installation in addition to excellent operational performance.
Saint-Gobain supplies refractory linings for all common type of reactors, including bricks for diffusor domes, connectors, manhole, and transfer line.

A large number of secondary reformers for syngas production have been lined with Saint-Gobain materials. All listed refractories from Saint-Gobain have been approved by the major design and engineering companies. The hydrogen rich atmosphere requires high-purity refractories with low silica content in the hot face as well as in the insulating layers.
AL 100, Alfrax® 101 and Alundum® AH199 high-density alumina bricks are devoted to the hot face from the burner down to the diffuser dome or catalyst arch support. Pural T and CA334 castables are suitable for the wall lining of the vessel. Bubble alumina insulating fire bricks and castables AN599, RI 34 or CA333 are preferred as insulating layer materials. Saint-Gobain also supplies alumina lumps and alumina balls as catalyst support media.
Different sizes and designs of hexagonal target tiles and special shapes are available for all major process technologies (e.g. HaldorTopsoe, KBR, Uhde).
Unlike the smaller sized ammonia production lines where the secondary reformers may be lined with monolithics, autothermal reactors for the methanol production run at higher temperatures and require high-purity alumina bricks in the hot face and in the backup.
Dense AL 100, Alfrax® 101 and Alundum® AH199 bricks and bubble alumina RI34 or Alundum® AH599 insulating fire bricks are recommended in the various layers. These materials have been installed in the largest units around the world and are approved by the major design and engineering companies.
