Abstract

Ammonia (NH₃) is one of the main contaminants in the biomass gasification producer gas, which is undesirable in downstream applications, and thus must be removed. When the producer gas is used in integrated gasification combined cycle (IGCC) technology, NH₃ is the main precursor of nitrogen oxides (NO_x) formed in gas turbine, whereas in Fischer–Tropsch synthesis and in integrated gasification fuel cell (IGFC) technology, the NH₃ gas poisons the catalysts employed. This paper presents a critical review on the recent development in the understanding of the NH₃ formation in biomass gasification process and in the NH₃ gas cleaning technologies. The NH₃ gas concentration in the producer gas can firstly be reduced by the primary measures taken in the gasification process by operation optimisation and using in-bed catalytic materials. Further removal of the NH₃ gas can be implemented by the secondary measures introduced in the post-gasification gas-cleaning process. Focus is given on the catalytic gas cleaning in the secondary measures and its advantages are analysed including energy efficiency, impacts on environment and recyclability of the catalyst. Based on the review, the most effective cleaning process is proposed with integration of both the primary and the secondary measures for application in a biomass gasification process.
