Title: Catalytic cartridge SO3 decomposer

Patent ·
OSTI ID:5194791

A catalytic cartridge surrounding a heat pipe driven by a heat source is utilized as a SO3 decomposer for thermochemical hydrogen production. The cartridge has two embodiments, a crossflow cartridge and an axial flow cartridge. In the cross-flow cartridge, SO3 gas is flowed through a chamber and incident normally to a catalyst coated tube extending through the chamber, the catalyst coated tube surrounding the heat pipe. In the axialflow cartridge, so3 gas is flowed through the annular space between concentric inner and outer cylindrical walls, the inner cylindrical wall being coated by a catalyst and surrounding the heat pipe. The modular cartridge decomposer provides high thermal efficiency, high conversion efficiency, and increased safety.
