ABSTRACT:
A catalytic element is encased in a shell in such a way as to be held tightly between shell halves but not fixed to same. A pair of stoppers for preventing endwise movement of the catalytic element is provided to the shell. A predetermined clearance is provided between each of the stoppers and each end of the catalytic element so as to allow such movement of the catalytic element relative to the shell that results from a thermal expansion differential between the catalytic element and the shell.
