Promoters are the substances that enhances (increases) the activity of the catalyst. Example : In the manufacture of ammonia by Haber's process molybdenum is a promoter to the catalyst iron. In an adsorption experiment, a graph between log (xm) versus log P was found to be linear with a slope of 45∘ .20.

Answer 2

Answer:

Promoter is any component added to a catalyst to increase activity or selectivity. Examples are tin added to platinum reforming catalysts to improve selectivity to coke formation and chloride added to isomerization catalysts to increase activity.
