Book Description
An increasing amount of ammonia slip affects DeNOx technology used to reduce nitrogen oxides emissions from power plants and other stationary sources of NOx emissions, heavy trucks, gasoline and Diesel passenger cars. The control and removal of ammonia emissions in waste streams are required. The process of the selective catalytic oxidation of ammonia into nitrogen and water vapour is one of the most promising methods for elimination of toxic ammonia from flue gases. As catalysts for the process hydrotalcite-derived mixed metal oxides were tested. The studies performed in the frame of the research were presented in four scientific papers (Catalysis Letters, Applied Catalysis B: Environmental, Journal of Thermal Analysis and Calorimetry, Chemik). Mixed metal oxides have been found to be active, selective to nitrogen and stable in ammonia oxidation. Their activity and selectivity strongly depend on chemical and phase composition and their redox properties. Optimum composition of the catalysts guaranteeing high catalytic performance was proposed. The internal SCR (i-SCR) mechanism was investigated for the reaction performed over the studied catalysts.

Book Description
The main objective is to look at ways by which ammonia can be catalytically removed from gaseous waste streams via the selective catalytic oxidation (SCO) of ammonia to nitrogen and water. The book also looks at methods of catalysts preparations (such as impregnation, ion exchange and hydrothermal synthesis) and characterisation techniques (such as TPD, XPS, elemental analysis and nitrogen physisorption. The results of the selective catalytic oxidation of over Fe-ZSM-5 are also presented. Life time study on catalyst performance are also presented.

Book Description
The results of the hydrothermal oxidation of 1,8 diazabicyclo[5.4.0]undec-7-ene (DBU), a toxic nitrogen-containing organic compound by different processes is presented here. Subcritical experiments (wet air oxidation (WAO) and catalytic wet air oxidation(CWAO)), were conducted in a batch reactor and supercritical water oxidation (SCWO) experiments were conducted in a tubular reactor. The key operating parameters investigated were temperature, pressure, initial organic concentration; for catalytic experiments, the effect of catalyst metal loading and weight were also investigated. Commercially available Ru/Al\(_2\)O\(_3\) pellets were selected for catalytic study after various catalysts were screened. Results indicated that temperature was the key operating parameter in all 3 processes that affected DBU removal, TOC removal and ammonia yield. Ru/Al\(_2\)O\(_3\) pellets enhanced the DBU removal, TOC removal and decreased ammonia yield compared to WAO. Complete DBU removal was achieved by catalytic wet air oxidation and supercritical water oxidation. Kinetic data was acquired and a pseudo first order kinetic model was used to quantify the oxidation rate. WAO and CWAO were investigated for the treatment of hazardous industrial effluent with a high initial ammonia concentration and complete ammonia removal was achieved using Ru/Al\(_2\)O\(_3\) pellets. A novel ruthenium coated reticulated foam monolith was investigated as an alternative for heterogeneous catalyst instead of Ru/Al\(_2\)O\(_3\) pellets, the results show that it improved catalyst stability and could be an alternative to pellets for wastewater treatment.
