Catalytic cartridge so.sub.3 decomposer

Abstract From the Canadian patent

Abstract of the Disclosure, 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 cross-flow 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 axial-flow 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 …
