Description
Applied in isomerization of light gasoline fractions for production of Euro-5 fuels.
Application
Advantages and Features
- Resistant to skips of sulfur, nitrogen and water; process upsets do not result in irreversible loss of activity;
- Activity and conversion degree of normal paraffins competing with chlorinated alumina catalysts;
- The injection of chloriding agent is not required to maintain catalyst activity;
- Is more advantageous for naphthenic ring - opening compared to chlorinated alumina catalyst;
- High selectivity contributes to low hydrogen consumption and decreases the content of low-octane С7naphthenic hydrocarbons;
- Resistant to fluctuations of feed space velocity: 0.5 to 3.0h-1;
- Cycle length upon condition of technology requirements is 5-6 years;
- Regenerability: withstands 3-4 regenerations without losing activity;
- Lifetime is 10-12 years.
