Abstract
The present invention, in some embodiments, provides catalyst modules and/or catalytic reactors having increased effective catalyst cross-sectional areas. In some embodiments, a catalyst module comprises a fluid stream inlet side comprising a plurality of first catalyst bodies and a plurality of first ducts and a fluid stream outlet side comprising a plurality of second catalyst bodies and a plurality of second ducts, wherein the first ducts are a fluid stream inlet to the second catalyst bodies and the second ducts are a fluid stream outlet for the first catalyst bodies.
