Trends in NOx abatement: A review

Implementation of stringent regulations of NOx emission requires the development of new technologies for NOx removal from exhaust gases. This article summarizes current state of NOx abatement strategy. Firstly, the influence of NOx on environment and human health is described. The main focus is put on NOx control methods applied in combustion of fossil fuels in power stations and mobile vehicles, as well as methods used in chemical industry. Furthermore the implementation of ozone and other oxidizing agents in NOx oxidation is emphasized.
