The majority of the hydrogen and syngas currently produced is generated via steam methane reforming (SMR), a process in which high-temperature steam is reacted with natural gas. This reaction typically takes place in chromium-nickel tube reactors steel which degrade over time, releasing chromium that can deposit on downstream equipment. The flue gas from the burners contains nitrogen oxides (NOx) and carbon monoxide (CO) which cause air pollution if not removed from the exhaust.
Johnson Matthey Selective Catalytic Reduction (SCR) catalysts reduce NOx from SMR flue gas by more than 90%, with low ammonia slip. The SINOx® extruded honeycomb catalyst is durable and is resistant to chromium poisoning, allowing long catalyst lifetime. The catalyst is built into heavy-duty steel modules that facilitate installation.
