Catalyst elemental analysis


Catalyst elemental analysis

Admixtures of Fe (Iron), Cu (Copper), Ni (Nickel), V (Vanadium) and other elements containing in the catalyst raw material can change the catalyst properties. For example iron oxide (III) especially accompanied by nickel, vanadium, copper oxides lead to deeper hydrocarbons decomposition and therefore intensive coke production, increase of gas output. And even to decomposition into carbon and hydrogen in some cases.

Precious metal containing catalysts (gold, silver, platinum group) are always recycled to extract valuable components. Reforming, in hydrotreating, isomerization catalysts are included in this group. Hydrofining and hydro cracking  catalysts contain significant amount of nickel, cobalt, molybdenum, tungsten that can be efficiently regenerated with modern methods.

X-ray fluorescence analysis provides elements determination in catalysts with minimum sample preparation. XRFA sensitivity is sufficient for determination of considerable amount of admixtures and valuable components of catalyst.

Water and petroleum products are removed by burning at the first sample preparation stage. Then the sample material is grinded to the particle size of 50-70 micron, and then it is pressed in pellets. The pellets are analyzed in spectrometer automatically according to the chosen program. Results are calculated with preliminary prepared calibration curve.
