Porous structure for fluid contact

Claim 2

A porous structure through which at least one fluid flows, comprising: a plurality of stacked packings, each stacked packing including a plurality of adjacently located honeycomb blocks, each honeycomb block comprising: a plurality of first partition walls extending in a first direction and having a longitudinal axis, each of said first partition walls being spaced apart from each other in a second direction which is substantially perpendicular to said first direction, and said plurality of first partition walls being in a substantially parallel relationship; a plurality of second partition walls extending in said second direction, such that each second partition wall contacts two adjacent first partition walls along a substantial length of each of said second partition walls, said second partition walls being spaced apart from each other and being inclined relative to said longitudinal axis of the first partition walls, said first and second partition walls cooperating to form a plurality of inclined parallel channels in each honeycomb block; and said adjacently located honeycomb blocks in each of said stacked packings having all longitudinal axes of the first partition walls of each honeycomb block in a substantially parallel relationship with each other and said inclined parallel channels of adjacent honeycomb blocks are inclined with regard to each other, and when said packings are superposed, inclined channels of honeycomb blocks in a first packing communicate with inclined channels of corresponding honeycomb blocks in a second packing in a zigzag manner, thereby forming a plurality of zigzag fluid passages through the porous structure.

Claim 3

The porous structure of claim 1, wherein said second partition walls have perforations formed through the thickness thereof, said inclined parallel channels in said each honeycomb block communicating with each other through said perforations to result in a substantially even distribution of fluid in said plurality of inclined parallel channels.

Claim 4

The porous structure of claim 1, wherein said plurality of honeycomb blocks comprise at least two differently shaped blocks oriented in said stacked packing in an alternating arrangement.

Claim 5

The porous structure of claim 1, wherein said second partition walls are inclined at an angle of 45-75 degrees with respect to said longitudinal axis of the first partition walls.

Claim 6

A porous structure through which at least one fluid flows, comprising: a plurality of stacked packings, each stacked packing including a plurality of adjacently located honeycomb blocks, each honeycomb block comprising: a plurality of first partition walls extending in a first direction and having a longitudinal axis, each of said first partition walls being spaced apart from each other in a second direction which is substantially perpendicular to said first direction, and said plurality of first partition walls being in a substantially parallel relationship; a plurality of second partition walls extending in said second direction, such that each second partition wall contacts two adjacent first partition walls along a substantial length of each of said second partition walls, said second partition walls being spaced apart from each other and being inclined relative to said longitudinal axis of the first partition walls at an angle of 45-75 degrees, said first and second partition walls cooperating to form a plurality of inclined parallel channels in each honeycomb block and said second partition walls have performations formed through the thickness thereof to result in a substantially even distribution of fluid in said plurality of inclined parallel channels; and said adjacently located honeycomb blocks in each of said stacked packings having all longitudinal axes of the first partition walls of each honeycomb block in a substantially parallel relationship with each other and said inclined parallel channels of adjacent honeycomb blocks are inclined with regard to each other, and when said packings are superposed, inclined channels of honeycomb blocks in a first packing communicate with inclined channels of corresponding honeycomb blocks in a second packing in a zigzag manner, thereby forming a plurality of zigzag fluid passages through the porous structure.

Claim 7

A porous structure through which at least one fluid flows, comprising: a plurality of stacked packings, each stacked packing including a plurality of adjacently located honeycomb blocks, each honeycomb block comprising: a plurality of first partition walls extending in a first direction and having a longitudinal axis, each of said first partition walls being spaced apart from each other in a second direction which is substantially perpendicular to said first direction, and said plurality of first partition walls being in a substantially parallel relationship; a plurality of second partition walls extending in said second direction, such that each second partition wall contacts two adjacent first partition walls along a substantial length of each of said second partition walls, said second partition walls being spaced apart from each other and being inclined relative to said longitudinal axis of the first partition walls at an angle of 45-75 degrees, said first and second partition walls cooperating to form a plurality of inclined parallel channels in each honeycomb block and said second partition walls have performations formed through the thickness thereof to result in a substantially even distribution of fluid in said plurality of inclined parallel channels; and said adjacently located honeycomb blocks in each of said stacked packings having all longitudinal axes of the first partition walls of each honeycomb block in a substantially parallel relationship with each other and said inclined parallel channels of adjacent honeycomb blocks are inclined with regard to each other, and when said packings are superposed, inclined channels of honeycomb blocks in a first packing communicate with inclined channels of corresponding honeycomb blocks in a second packing in a zigzag manner, thereby forming a plurality of zigzag fluid passages through the porous structure.

Claim 8

The porous structure of claim 5, wherein the perforations in said second partition walls permit said inclined parallel channels to communicate with each other.

Claim 9

The porous structure of claim 5, wherein said plurality of honeycomb blocks comprise at least two differently shaped blocks oriented in said stacked packing in an alternating arrangement.
