Catalyst Regeneration in Light Naphtha Aromatization(LNA) Process.

Advances in Catalyst Deactivation and Regeneration

Effective use of catalysts through catalyst regeneration

The refining industry is currently undergoing its most serious challenge in recent times, since cleaner fuels are gradually introduced in many markets. Middle East countries still have less history than Europe, Japan or the USA when it comes to clean fuels, but the trend is there, which will eventually increase the demand for hydroprocessing catalysts. On the other hand, more sophisticated cata...

Nitrogen Chemistry and Coke Transformation of FCC Coked Catalyst during the Regeneration Process

Regeneration of the coked catalyst is an important process of fluid catalytic cracking (FCC) in petroleum refining, however, this process will emit environmentally harmful gases such as nitrogen and carbon oxides. Transformation of N and C containing compounds in industrial FCC coke under thermal decomposition was investigated via TPD and TPO to examine the evolved gaseous species and TGA, NMR ...

Heterogeneous Catalyst Deactivation and Regeneration: A Review

Deactivation of heterogeneous catalysts is a ubiquitous problem that causes loss of catalytic rate with time. This 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). The key...

Self-regeneration of a silylium ion catalyst in carbonyl reduction.

The silylium ion-catalysed reduction of carbonyl compounds to the alcohol oxidation level is accomplished by exploiting the unique reactivity of a ferrocenyl-substituted silane.
