Conventional Reactor - an overview | ScienceDirect Topics

Conventional reactor designs address the issue of longitudinally moderating heat generation by judiciously distributing the fuel feed, or using multiple external heat exchangers. These ideas are difficult to implement directly at the small scales of CPRs, but can be emulated by a segmented combustion catalyst configuration (Figure 1), consisting of alternating catalytically active and inactive .

Reactor Design:

The tube side inlet pressure is 261 psia, and the shell side inlet pressure is 243 psia. The pressures are determined by the reactor pressure requirements. Stainless steel is chosen for both the tube and shell sides because there is a large amount of EO flowing through the shell and possible trace amounts of EO in the tube side.

Strategies for Carbon and Sulfur Tolerant Solid Oxide Fuel .

Solid oxide fuel cells (SOFCs) are a rapidly emerging energy technology for a low carbon world, providing high efficiency, potential to use carbonaceous fuels, and compatibility with carbon capture and storage. However, current state-of-the-art materials have low tolerance to sulfur, a common contaminant of many fuels, and are vulnerable to deactivation due to carbon deposition when using .
