The refineries must face the threaten of the extended ranges of the poisons to the hydro-processing unit because of the feed sources’ varieties. Many of the contaminants found can cause catalyst bed poisoning event at very low concentrations, which will result in lots of operation problems and make negatively impacts to the R.O.I of the plants, for this reason many of the research institutes of oil refinery and petrochemical invented and developed many solutions to protect the main catalyst from poisoning.

SINOCATA also provide wide ranges of the topping, grading and bed support materials with lower cost and high performance to the market, we supplies a variety of low pressure drop bed topping materials and bed supports. These include the traditional graded beds of support media, but also advanced materials and shapes that are tailored to the user’s request, including shaped ceramic rings, honeycomb discs, metal impregnated hollow ring, cylindrical extrudate, trilobe extrudate, quadralobe extrudate and inert balls etc.

SINOCATA supplies a variety of low pressure drop bed topping, bed grading, bed support materials to protect your catalytic unit and catalyst investment.

Inert Topping Media

Inert Topping MediaSINOCATA provide two kinds of inert topping media, the ICT serial and the IFS serial.

The ICT serial – bed topping is using inert ceramic shaped rings with a high void fraction to provide an efficient capture of particulates and other contaminants in the feed. The SINOCATA inert topping media provide a high void volume and good distribution to low the pressure.

The AD serial – bed topping media is the new generation of bed design technology for active filtration system, the bed protection filter disk grading technology which is using high purity alumina. This technology is used to filter fines in hydrotreating units, sulfur guard beds, chloride guard beds and lower the pressure drop of the reactors.

Active Bed Grading Media

Active Grading MediaSINOCATA provide four kinds of active bed grading media, the CGR, GCC, GCT and the GCQ serial which were delivered at a very cost effective, environmentally and friendly way to maximize overall catalyst bed life and minimize the pressure drop.

The GCR serial – GCR Serial is a NiMo/CoMo hollow rings with mild activity designed for use as top bed grading in a variety of hydroprocessing unit applications. The products has very excellent physical strength, also provides high void space for particulate trapping. SINOCATA offer 1/8″(3.2mm), 3/16″(4.8mm), 1/4″(6.0mm), 3/8″(9.0mm) for active Hollow Rings.

The GCC serial – GCC Serial is a NiMo/CoMo cylindrical extrudates with mild activity designed for use as top bed grading in a variety of hydroprocessing unit applications. The products has very excellent physical strength. SINOCATA offer 2.5mm for cylindrical extrudate.

The GCT serial – GCT Serial is a NiMo/CoMo trilobe extrudates with mild activity designed for use as top bed grading in a variety of hydroprocessing unit applications. The products has very excellent physical strength. SINOCATA offer 2.5mm for trilobe extrudate.

The GCQ serial – GCQ Serial is a NiMo/CoMo quadralobee extrudates with mild activity designed for use as top bed grading in a variety of hydroprocessing unit applications. The products has very excellent physical strength. SINOCATA offer 2.5mm for quadralobee extrudate.
