Technical Method · ECOSAILWhy Catalyst Selection Starts With the Full Load Curve
A continuous operating record from a 3 MW-class gas engine showed a higher exhaust temperature at part load than at full load. That finding changed the catalyst route.
One Trend Changed the Initial Assumption
The unit operated around the clock, rising to full load during the day and returning to about 50% load overnight. The sustained part-load condition produced the upper edge of the real temperature window.
Return From the Catalyst Datasheet to the Machine
Temperature range is only the first screen. Fuel sulfur, potential poisons, dust, space velocity, allowable pressure loss and expected service life still need to be reviewed together.
Translate Selection Into System Design
Reactor area, catalyst volume, dosing range, mixing distance and control logic should be checked at each representative load point rather than only at rated power.
