Superior catalysts for selective catalytic reduction of nitric oxides; Quarterly technical progress report, October 1, 1993--December 31, 1993

PDF Version Also Available for Download.

Description

Work was done in three tasks during the first quarter. In Task 1, a new SCR reactor system has been built, complete with on-line GC and MS analyses. The GC is used to monitor the N{sub 2} product so the NO{sub x} > N{sub 2} conversion can be calculated. The MS is used to analyze the N{sub 2}0 concentration. In addition, a wet analytical technique has been established for SO{sub 3} analysis. The new SCR system and the SO{sub 3} analytical technique have been subjected to shakedown tests with success. Along with the existing SCR reactor system, there are now ... continued below

Description

Work was done in three tasks during the first quarter. In Task 1, a new SCR reactor system has been built, complete with on-line GC and MS analyses. The GC is used to monitor the N{sub 2} product so the NO{sub x} > N{sub 2} conversion can be calculated. The MS is used to analyze the N{sub 2}0 concentration. In addition, a wet analytical technique has been established for SO{sub 3} analysis. The new SCR system and the SO{sub 3} analytical technique have been subjected to shakedown tests with success. Along with the existing SCR reactor system, there are now two systems that are being run independently. In Task 2, a procedure for the synthesis of stable Fe{sub 2}O{sub 3} Pillared clay has been established. Inductive coupled plasma spectrometric analysis (ICP) has been used to analyze the chemical composition of the Fe{sub 2}O{sub 3} Pillared clay. Preliminary results for the SCR activities of the Fe{sub 2}O{sub 3} pillared clay are obtained in Task 3. The results show that the activities are near that of the commercial V{sub 2}O{sub 5}/TiO{sub 2} catalysts. However, the SO{sub 2}-to-SO{sub 3} conversion is substantially lower with the pillared clay catalyst, which could be an important advantage.
