How Do Catalytic Heaters Work? | Hunker

A catalytic heater works by increasing the speed of a chemical reaction. In doing so, heat is produced. This enables the unit to emit heat that can be safely used in a variety of scenarios, such as in offices, at campgrounds or at work sites. Carbon monoxide is not a concern with catalytic heaters.

FILTRATION APPLICATIONS IN CATALYTIC REFORMING

Some catalytic reforming units may have an extra spare or swing reactor allowing each reactor to be individually isolated so that any one reactor can be undergoing regeneration while the other reactors are in operation. When that reactor is regenerated, it replaces another reactor which, in turn, is isolated so that it can then be regenerated.
