High iC4/nC4 Equilibrium and High Octane C5/C6 Cuts via Isomerization Processes

Isomerization Catalysts

High iC4/nC4 equilibrium

High iC4/nC4 equilibrium

Chlorinated alumina is the catalyst of choice thanks to its high activity permitting operation at lower reactor temperatures that enable higher iC4/nC4 equilibrium and favor superior yields. The use of molecular sieve adsorbents on the feed and hydrogen make-up streams ensures the removal of feed contaminants and long catalyst lifetimes.

Axens isomerization technology uses ATIS-1L catalyst, which provides an unsurpassed combination of high activity, low cost, and low platinum content.

ATIS-1L

ATIS-1L is used in refinery for the isomerization of paraffinic C4 cuts resulting in improvement of the iC4/nC4 equilibrium.

Drying Series Adsorbents

Water removal applications are widely encountered in the industry sector. Activated alumina and molecular sieves stand at the forefront of the several different materials available on the market.

Chloride Removal Adsorbents

Chloride is important in both catalytic reforming and isomerization as it helps to maintain catalytic activity over time. However, as chloride is continuously fed into these units, it also has to exit.

Sulfur Removal Adsorbents for Oil, Gas & Petrochemicals

Hydrogen sulfide (H₂S), COS, mercaptans or sulfides are common contaminants that must be removed from various gases and liquids such as natural gas, NGLs, LPGs, cracked gases, olefins or biogas.
