Present challenges of NH3 production

Present challenges of NH3 production Ilenia Rossetti Chemical Plants and Industrial Chemistry Group, Dipartimento di Chimica, Università degli Studi di Milano (Italy) Ammonia synthesis represents one of the milestones of industrial chemistry. Nevertheless, huge efforts are still needed to improve productivity and lowering production costs. These challenging issues involve on one hand catalyst formulation, to solve some intrinsic limitations of the commercial Fe-based ones. On the other hand, process intensification is needed to optimise productivity while lowering the energy consumption, which mainly means the search for low pressure ammonia synthesis options. Some of these points will be reviewed in light of the most recent advancements in research, both from the point of view of materials and processes design.
