Method for improving wall heat transfer in a chemical reactor
First Claim
1. A method for improving heat transfer of a reactor wherein the reactor comprises mesh media comprising microfibrous entrapped catalysts (MFEC) and/or microfibrous entrapped sorbents (MFES), wherein the mesh media comprises micron-sized fibers, the method comprising:
- sintering the mesh media to an interior reactor wall to form metal junctions between the interior reactor wall and the micron-sized fibers, wherein the sintering step is a thermo-chemical sintering process comprising the step of applying a reducing gas, wherein the mesh media and the interior wall comprise a material that is the same, and wherein prior to the step of applying a reducing gas, the mesh media comprises fibers of a metal oxide.

Abstract
Methods for improving heat transfer at the interface between the internal reactor wall and mesh media containing microfibrous entrapped catalysts (MFECs) and/or microfibrous entrapped sorbents (MFESs) are described herein. Improved (e.g., more rapid) heat transfer can be achieved using a variety of approaches including increasing the contacting area of the interface between the mesh media and the reactor wall so that more contacting points are formed, enhancing the contacting efficiency at the contacting points between the mesh media and the reactor wall, increasing the number of contact points between the mesh media and the reactor wall using fine fibers, and combinations thereof.
