✦ Synopsis

The problem of chemxal reactlon and ddFuslon m a sphencal porous catalyst partlcle Immersed m a non-umform envlronment has been solved by the hneanzatlon techmque of Schdson and Amundson together wlth fimte Legendre transforms It was found that a wlde range of temperature gradlents extsts throughout the partlcle for the numencal example chosen Desplte thts, the overall effecttveness factor was not too much different from the one for a umform envlronment Thus, very large extemal gradlents would be reqmred to slgmficantly affect smgle reactton results, although the same would probably not be truc for selectlvlty wlth complex reactlons

The large diameter (up to 100 mm) Split Hopkinson Pressure Bar (SHPB) setup is used throughout the world to test large-cell heterogeneous materials, small structures, etc. This paper proposes a correction method to take into account the non-uniform distribution of stress and particle velocity (non-p
