Errata: Selective Catalytic Reduction of NOX in the Presence of Oxygen (Industrial & Engineering Chemistry Research (1994) 33(10) (2259–2264)(10.1021/ie00034a002))

Page 2260. Our article in the Metzner Festschrift of Ind. Eng. Chem. Res. stimulated a large number of telephone calls which, in turn, has resulted in visits to some of these inquirers by University and sponsor representatives. These visits and telephone calls essentially always want clarification of the statement in the article (Ind. Eng. Chem. Res. 1994,33,2259′2264), page 2260, second column, the last paragraph in that column. This statement is “The adsorbent now containing more than 0.2% NOX by weight.” The question is “How much more?” The answer is “Depending on the particle size and space velocity it may be 15%-25%. For example, at a space velocity of 12 000, as 4-8 mesh granules or supported on honeycomb, and at a temperature 180-200 °C the capacity is at least 18% NOX. Another question that comes up is “Is there any way to make this a continuous operation?”, and our answer is that under adequate permissible pressure drop allowance, we believe it could be adopted to a fluidized bed system. A drawing of such a system is presented herewith for individual consideration (Figure 1). The explanatory notes are on the diagram and depict the visualized procedure.
