3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Vanadium catalyst vanadiumcatalyst
The rate of change with certain chemical reactions resulting vanadium compound and its carrier, but do not themselves participate in the chemical reagent, known as
Vanadium catalyst or a vanadium catalyst.
3.2
Vanadium spent catalyst spentvanadiumcatalyst
Vanadium catalyst desulfurization of crude oil or petroleum cracking process used in the process fail after the residue poisoning. Vanadium catalyst poisoning saturated lose catalysis
Or after desulfurization, and then the new vanadium catalyst to replace down, so down to be replaced, said vanadium catalyst vanadium touch of coal waste.
4 Method summary
Sample heating at elevated temperatures in a porcelain dish, and removing carbon-based oil, and then all transferred to a conical flask, dissolve with phosphoric acid, sulfuric acid, nitric acid. in
Sulfuric acid medium was added ammonium persulfate vanadium from tetravalent to pentavalent oxidation. In N- phenyl anthranilic acid as indicator, ferrous ammonium sulfate standard
Titrate. The content of the sample is calculated based on the consumption of vanadium pentoxide ammonium ferrous sulfate standard solution.
5 Reagents
