Mechanisms of catalyst deactivation
TL;DR: The literature treating mechanisms of catalyst deactivation is reviewed in this paper, which can be classified into six distinct types: (i) poisoning, (ii) fouling, (iii) thermal degradation, (iv) vapor compound formation accompanied by transport, (v) vapor solid and/or solid solid reactions, and (vi) attrition/crushing.
Journal ArticleDOI
Heterogeneous Catalyst Deactivation and Regeneration: A Review
TL;DR: In this article, a review on deactivation and regeneration of heterogeneous catalysts classifies deactivation by type (chemical, thermal, and mechanical) and by mechanism (poisoning, fouling, thermal degradation, vapor formation, vapor-solid and solid-solid reactions, and attrition/crushing).
Journal ArticleDOI
Carbon Deposition in Steam Reforming and Methanation
TL;DR: In this article, the authors investigated the causes of deactivation of supported metal catalysts by carbon or coke formation, and found that deactivation can occur due to fouling of the metal surface, blockage of catalysts pores and voids, and actual physical disintegration of the catalyst support.
Journal ArticleDOI
The stoichiometries of H2 and CO adsorptions on cobalt: Effects of support and preparation
TL;DR: In this article, high temperature hydrogen adsorption and conventional 298 K adsorptions of hydrogen and carbon monoxide were characterized by unsupported cobalt and cobalt supported on silica, alumina, titania, magnesia, and carbon.
Journal ArticleDOI
Effects of support and dispersion on the CO hydrogenation activity/selectivity properties of cobalt
TL;DR: In this article, specific activity and selectivity of unsupported cobalt and cobalt supported on alumina, silica, titania, carbon, and magnesia carriers for CO hydrogenation were measured in a single-pass differential reactor at low conversions, 1 atm, and 175-350 °C.
