Catalyst-Analysis

Analyses on the unregenerated catalyst :

Carbon (C, wt %, method Lab001/002).
Sulfur (S, wt %, method Lab001/002).
Free hydrocarbon level (HC, wt %, method Lab008) is measured to decide whether catalyst stripping is necessary before regeneration. It corresponds to the quantity of material extracted with boiling toluene.
Loss On Ignition (LOI, wt %, method Lab006) is given by the loss of weight after 4 hours at XXX °C in a muffle furnace (Temperature may vary with catalyst type).
Length (l, mm, method Lab010) : It represents the average length of approximately 100 catalyst particles.

Analyses on lab regenerated catalyst :

Carbon : checks the efficiency of coke removal.
Sulfur : provides sulfur specification ex sulfides.
Surface area (SA, m2/g, methods Lab004/005), used for fixing SA specification on final product.
Bulk Crushing Strength (BCS, MPa, method Lab011) used for fixing BCS specification.

Analyses on industrially regenerated catalyst :

C, S, BCS, SA, check that industrially regenerated catalyst is within specifications.
Length : checks that catalyst pellets have not been seriously shortened.
Various densities, as well as Void Fraction, are also measured for providing valuable information for reactor loading.
