a pair of generally radially opposed, laterally extending outer flanges, the
outer side wall presenting a pair of axially opposed, circumferentially
extending marginal edges;
an inner saddle-shaped shell element including a porous inner semi-cylindrical
side wall and
a pair of radially opposed, laterally extending inner flanges, the inner side
wall presenting a pair of axially opposed, circumferentially extending
marginal edges;
a means for securing the outer and inner flanges together;
a means for closing off the interior space between the marginal edges of the
outer and inner shell elements;
the outer and inner side walls being spaced from one another to define an interior
space; and
a particulate catalyst component retained in the interior space between the side
walls.
15. A saddle packing structure comprising:
an outer saddle-shaped shell element including a porous, semi-cylindrical screen
defining an outer side wall;
an inner saddle-shaped shell element connected to the outer shell element and
including a porous, semi-cylindrical screen defining an inner side wall that is spaced
from the outer side wall to define an interior space;
a pair of axially opposed end walls for closing off the interior space between the
side walls of the outer and inner shell elements; and
a particulate catalyst component retained in the interior space between the side
walls of the outer and inner shell elements.
