Dinex Catalyst concept for H 2 engines going the extra mile All You Need From Turbo To Tailpipe Hydrogen Combustion Engines (H 2 ICE) will play a vital role in decarbonization of heavy duty applications. Hydrogen is a carbon-free fuel, and ICEs has a proven track-record of robustness, cost efficiency and well-established supply chains. In combination, they are a shortcut for getting started on the Hydrogen economy. But what about pollutant emissions? Testing and measuring the emissions of a H 2 ICE will reveal a set of technical challenges, primarily revolving around NO X emissions, that require a unique aftertreatment solution. Dinex has that solution. Combination of NO X Storage Catalyst with Ammonia SCR mixer PF* NSC SCR * Particulate Filtre (PF) is optional NO X Storage Catalyst (NSC): • removes NO X in cold start by passive NO X adsorption up to 120 – 150°C – and release by desorption above 150°C • increases NO 2 /NO X ratio to enhance NO X reduction efficiency of the SCR SCR: • high DeNO X in operation window 180 – 400°C • tolerant to high H 2 O content of 20–30% in the exhaust gas • very low secondary emissions Read more Dinex NSC for H 2 ICE The NSC is designed store NO X at low temperatures and to generate NO 2 in the temperature operation window of the SCR to improve DeNO X efficiency. Adsorption capacity 120°C: 4,8mg NO / g wash coat NO 2 Formation of NSC Dinex.net
