Calcination is an important step in catalyst synthesis. This work examd. plasma treatment as an alternative to calcination, since it is a more energy efficient process. A radio frequency, fluidized bed plasma reactor was used for the pretreatment process with different gas mixts. (Ar and Ar/O2 mixts.) over Pd/gamma-Al2O3 catalysts generally used for the DeNOx processes with CH4. Initial catalytic results obtained using plasma-treated catalysts clearly showed plasma treatment can replace classic calcination performed at 500°C, leading to a sustainable catalyst synthesis for NOx redn. by hydrocarbons in stationary sources.
