A METHOD FOR IMPROVING MASS-TRANSFER INTO CATALYST MATRIX

摘要

A method for improving the transfer of material in a catalyst matrix is provided to transfer easily material floating on a surface of the catalyst matrix, by forming a net structure composed of micro-pores in the catalyst matrix. A mixture is prepared, wherein the mixture includes a catalyst composite and a micro-pore forming additive. The mixture is deposited on a carrier. The carrier is hardened at a temperature of 400-700°C, thereby forming a catalyst matrix having a net structure composed of giant micro-pores and fine micro-pores. The micro-pore forming additive is bubble generating organic material such as a surfactant, or polymer such as carbon nano-tube obtained by hardening polyethylene or polyurethane. The 0.1 wt.% of micro-pore forming additive is contained, based on the 100 wt.% of catalyst composite, in the mixture.
