| titleOfInvention | Ternary composite oxide type catalyst for catalytic combustion of VOCs and preparation method thereof |
| abstract | The invention belongs to the technical field of catalyst preparation, and particularly relates to a ternary composite oxide catalyst for catalytic combustion of VOCs (volatile organic compounds) and a preparation method thereof. The catalyst is a composite oxide containing three metal elements of Co, Fe and Al, wherein n (Co)/n (Al + Fe) =1: 1-6: 1, and n (Al) = n (Fe) =2: 1-10: 1, and the structure and the activity of the catalyst are regulated and controlled by adjusting the relative contents of the three metals. In the invention, Fe 2+ The catalyst is doped into CoAl spinel, the catalytic performance of the catalyst can be improved by utilizing the intermetallic synergistic effect, only a small amount of solvent is needed in the reaction process, the catalyst is green and environment-friendly, the preparation method is simple, the steps are easy to operate, the industrial operation cost can be reduced, the prepared catalyst is large in specific surface area and uniform in pore channel, gas mass transfer is facilitated, the VOCs ignition activity is outstanding at low temperature, the conversion efficiency is high, and the catalyst has good thermal stability. |
