CATALYTIC CARTRIDGE SO.SUB.3 DECOMPOSER

摘要

RL-8122 S-55, 125 CATALYTIC CARTRIDGE SO3 DECOMPOSER 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 provides high thermal efficiency, high conversion efficiency, and increased safety.
