Basic Reactions

SINOx®: Coated Honeycomb SCR

High specific surface area

High activity in low-dust flue gases (low volume)

Optimised pressure drop (thin metallic walls)

Variable length and number of cells (100-400 cpsi)

Low-dust flue gas applications(high-grade coal, oil, gas, diesel or WIP applications)

SINOx®: Extruded Honeycomb SCR

High specific surface area

High activity in low-dust flue gases (low volume)

Optimised pressure drop

Variable length and number of cells (6-300 cpsi)

Low-dust flue gas applications(high-grade coal, oil, gas, diesel or WIP applications)

SINOx®: Coated Plate SCR

Variable pitch, minimal dust deposition

High erosion, poison resistance
