Abstract

The invention relates to a process for removing ammonia from gasification gas by means of selective oxidation in the presence of a solid catalyst. The oxidising agent can consist of gaseous oxygen, O2, or a mixture of oxygen and one or more oxides of nitrogen, for example nitrogen monoxide NO. According to the invention, the catalyst used is silicon carbide, which catalyses the reaction within the temperature interval of approx. 600-900 degree C. The catalyst, which consists of small particles, can constitute a solid or liquid bed 12 in a separate oxidising reactor 11 which is located after the gasifier 1. <IMAGE>
