Patent ID: 7288231

Claim:
A chemical reactor comprising: at least one reaction chamber comprising at least one porous catalyst material and at least one open area wherein each of said at least one reaction chamber has an internal volume defined by reaction chamber walls; wherein said internal volume has dimensions of chamber height, chamber width and chamber length; wherein said at least one reaction chamber comprises a chamber height or chamber width that is about 2 mm or less; wherein, at a point wherein said chamber height or chamber width is about 2 mm or less, said chamber height and said chamber width define a cross-sectional area; said cross-sectional area comprising a porous catalyst material and an open area, wherein said porous catalyst material occupies 5% to 95% of the cross-sectional area and wherein said open area occupies 5% to 95% of the cross-sectional area; wherein said open area in said cross-sectional area occupies a contiguous area of 5×10 −8 to 1×10 −2 m 2 and wherein said porous catalyst material has a pore volume of 5 to 98% and more than 20% of the pore volume comprises pores having sizes of from 0.1 to 300 microns.
