Catalyst development for nitric acid plants is strongly dependent on operating pressures and nitrogen loading levels. Johnson Matthey reviews some of the key catalyst design principles, emphasising the critical role of operating pressure in catalyst selection and highlighting the innovative contributions of Johnson Matthey in advancing catalyst technology for ultra-high-pressure ammonia oxidation in nitric acid plants.

New blue production schemes are available to meet the need to significantly reduce the overall carbon intensity of high-volume hydrogen and ammonia production for a large-scale emerging market. KBR, Air Liquide, Mitsubishi Heavy Industries, Casale and Johnson Matthey report on their latest technologies.

Cobalt-molybdenum catalysts are integral components of tail gas units, playing a vital role in reducing harmful sulphur dioxide emissions arising from Claus sulphur recovery units. Effective activation of these catalysts is essential for their optimal performance. In the first part of this two-part article, Michael Huffmaster, Consultant, explores CoMo catalyst activation at low pressure, focusing on sulphiding reaction pathways and the impact of temperature and the composition of the sulphiding media on reaction kinetics.
