Description: Die Stickoxide NO, NO2 und N2O entstehen in mehr oder weniger starkem Maße bei jeder Verbrennung in Luft. Während NO und NO2 toxisch sind, wirkt N2O in der Atmosphäre als starkes Treibhausgas. Im Rahmen des Projektes sollen neue zeolith-basierende Katalysatorsysteme entwickelt werden, welche mit Kohlenwasserstoffen als Reduktionsmittel simultan NO und N2O zu Stickstoff reduzieren.

Title: Catalytic Abatement of N2O and NOx from Combustion Power Plants
Description: Objective: N2O is a powerful greenhouse gas and a precursor of stratospheric ozone depletion. NOx are also responsible for acid rain and photochemical smog. Combustion technology is an important source of both pollutants. The main objective is the development of an advanced, compact, efficient and cost-effective technology, based on the simultaneous selective catalytic reduction of N2O and NOx from combustion power plants by hydrocarbons. This will enable companies to comply with legal regulations at a reasonable cost while an environmental friendly image is created. The project deals with the development/improvement of active and selective catalysts stable over a meaningful time of continuous operation and with the acquisition of a fundamental understanding of process kinetics and mechanisms. Description of Work: The proposed work comprises the following tasks: - Catalyst Design and synthesis, including preparation of different type of supported and unsupported active catalysts, such as zeolite, clay, carbon, and metal/metal oxide based catalysts, in the form of powders, pellets, extrudates or monoliths. - Lab-scale testing, which consists of different screening tests for assessment of the catalyst activity and selectivity. Experiments are also foreseen in order to understand the basic scientific phenomena such as reaction kinetics, mechanisms of reaction and the mechanisms of inhibition and deactivation over the catalysts. - Catalysts Characterisation, using a series of physico-chemical techniques, in order to: a) ensure the effectiveness of preparation and the homogeneity and reproducibility of the fresh samples, b) seek insights into deactivation of the catalysts and c) gauge the effect of potential poisoning on used samples. - Bench-scale testing, aimed at the assessment of the lifetime of the catalysts. Two different tests, using simulated combustion gases, are designed for this purpose: a) accelerated deactivation tests, to simulate any possible deactivation of catalysts during their exposure to real combustion exhaust gases and b) long-term stability tests (up to 2000 hours) simulating the clean up of flue gases in conditions as close as possible to those found in industrial applications. Eventually, the performance of the catalysts will be evaluated with real combustion off-gases. Expected results and exploitation plans: - The development of selective, active, stable and durable catalyst prototypes, potentially transferable to various industrial user groups. This will put European industry in a position to offer an efficient, economic and advanced technique for the simultaneous removal of N2O and NOx in off-gas from combustion processes. - The acquisition of deep knowledge of the nature of selective catalytic reduction of N2O/NOx by hydrocarbons.
