The performance of a carbon black reactor is related to its refractory lining. High temperature reactors, designed to operate at temperatures >2,000°C, subject lining materials to extreme thermal, mechanical, and chemical stress as they convert feedstocks into high-quality carbon black. Saint-Gobain Performance Ceramics & Refractories have developed advanced lining solutions that combine high-performance alumina, zirconia and fused-cast materials along with dense and insulating castables to form robust linings that protect every zone of the carbon black reactor from erosion, corrosion, and heat loss. By aligning material composition and design with reactor temperature profiles and process conditions, these refractory systems promote stable operation, optimize thermal efficiency, and extend furnace campaigns.
Our proven lining materials include:
- Alundum® AH199 and AL100: High-purity alumina bricks offering excellent erosion resistance in the high-temperature combustion and reaction zones of carbon black reactors
- Mullfrax® 202 HF and AL102: Thermal-shock-resistant alumina materials designed to handle rapid cooling and heating in the quench and transition areas of the reactor
- Ziral™ and Zirnorite®: Zirconia-based bricks capable of withstanding temperatures up to 2,200°C in severe combustion zones, offering exceptional temperature resistance
- Jargal M fused-cast shapes: Erosion-resistant fused cast materials ideally suited for the choke and inlet sections of carbon black reactors, where gas and velocity and particle abrasion are at their highest.
- Supcast® / CA334 and RI34HR / CA333 castables: Dense and insulating alumina castables used in the backup layers of carbon black reactor linings to improve thermal insulation, mechanical strength, and overall energy efficiency.
