Learning outcomes

Design of industrial reactors is often dictated by secondary phenomena such as catalyst deactivation. The course gives an introduction to important deactivation phenomena illustrated by industrial examples. The course discusses application of catalysts in industrial processes and how to evaluate deactivation mechanisms.

Course main content

Secondary phenomena and plant design,sintering (support, metal crystals),poisoning (chemisorption, Ni/H2S example, diffusion, dynamics, regeneration, elution, other mechanisms, effectiveness factor & poisoning),routes to carbon (FCC example, gum formation, coke from pyrolysis), carbon formation on metals (steam reforming example, whisker carbon, criteria for carbon, regeneration),

 Fouling of Catalysts (interparticle (HDS example), intraparticle (flue gas catalysis),

 process influence on catalyst deactivation (feed, fuel and impurities, industrial examples), process influence on catalyst deactivation (influence of ash, dust and mechanical problems, industrial examples), Catalyst deactivation studies (field vs. laboratory evaluations).

Lectures and seminars are given by Aff. Prof. Jens Rostrup-Nielsen, Haldor Topsøe and Adj. Prof. Ann-Charlotte Larsson, Alstom.
