ARI-100 Series of Catalysts

The new ARI-100 Series of catalysts is the key to improved refinery and hydrocarbon processing operation. These improved cobalt catalytic reagents accelerate the oxidation of mercaptans in petroleum fractions.

Improved Cobalt-Based Catalytic Reagents Enhance Hydrocarbon Sweetening Processes

New catalysts, as well as enhanced versions of earlier ARI-100 Series cobalt-based catalysts, have been developed by Gas Technology Products (GTP) and Merichem Chemicals and Refinery Services (MCRS) for applications in hydrocarbon processing and refining.

ARI-100EXL

Solids-free ARI-100EXL, used in liquid to liquid contact processes,

• Is a 100% soluble solution
• Causes no solids formation
• Eliminates solids settling issues
• Minimizes DSO carryover
• Is compatible with continuous catalyst injection systems

ARI-120L

Now offered in powdered form, ARI-120L is a catalytic reagent for fixed bed processes,

• Reduces shipping costs
• Offers unlimited shelf life
• Reduces carbon bed impregnation time by 50%
• Offers the convenience of simple catalyst slurry preparation procedure
• Provides easy operator handling and transport via packaging in 5 gallon plastic pails
• Simplifies handling with 80% fewer containers required
• Provides access port in plastic pails for water addition, mixing, and pumping

CAC-120S

Long lasting and durable, CAC-120S is a catalytic reagent already adsorbed on the carbon surface. Used in fixed bed processes, CAC-120L

• Eliminates the need to impregnate replacement carbon with catalyst on-site
• A faster turnaround results in an additional 5–7 days of hydrocarbon sweetening production
• Simple wetting and causticizing are the only requirements prior to start-up of the sweetening process
• Superior quality is due to more uniform adsorption of catalytic reagent on carbon surface yielding more consistent results and extending sweetening life cycle
• Merichem ensures proper concentration of cobalt content in the carbon
• Cost savings are due to faster turnaround as well as costs associated with the impregnation process itself
• Pre-impregnated carbon can be re-impregnated at anytime as any other carbon
• CAC-120S minimizes the risk of lost production due to an improper on-site impregnation
