DuraTop® Covering layers for catalyst beds for more efficiency.

DuraTop® special reformed packings are used among other things for covering catalyst beds. DuraTop® special reformed packings can be added onto the top ball layer or even replace the top ball layer. As the top layers on the catalyst beds DuraTop® special reformed packings offer the following advantages: - low pressure drop because of large free-gap volume - good pre-distribution of the liquid and gaseous media, even before they reach the catalyst bed, due to open internal ...

DuraTop® und DuraFlow — Inert Covering Material and Pressure Drop-Reducer

DuraTop® and DuraFlow are used for the covering of catalyst and catalyst carriers (Duranit® inert balls) and are applied to the upper ball layers. In addition, it is possible to apply the two Pressure Drop-Reducer at different levels of the catalyst support bed or even to replace the upper spherical layers in an energy-saving manner. DuraTop® and DuraFlow are of course available in different sizes. In addition these products offer the following advantages: - Good pre-distribution ...

FCC technical support, industry-leading service

Grace technical service engineers regularly visit refineries to review unit operating data, evaluate catalyst management and unit performance, as well as provide specific recommendations to optimise unit operation. Grace can provide expert advice on operational problems concerned with the mechanical integrity of the FCCU. For example, issues such as cyclone performance, stripper efficiencies, circulation problems, transfer line problems, slurry circuit fouling, or high unit erosion ...

Grading & guard materials

Maximum catalyst protection and optimum pressure drop management. With the increased levels of heavy and non conventional crude oils in the refinery diets, state-of the art catalysts need state of the art Grading and Guard Materials to create the best working environment mitigating pressure drop and eliminating contaminants. Cycle length of a Hydroprocessing unit is typically controlled either by the catalyst activity (maximum allowable working temperature) or by the reactor ...

Low and zero rare-earth FCC catalysts

Rare-earth metals are an important component of FCC catalysts, as well as being a key raw material for many strategic industries with applications ranging from military devices to electronic components. In addition, they are essential constituents in newly evolving green technologies, such as hybrid cars and wind turbines. Rather ironically, rare-earth metals are not so rare, however they tend to be concentrated in hard to extract ore deposits. As a result, the world’s ...

MERICON™ spent caustic processing

MERICON™ technology provides an on-site solution for the processing of spent caustics to reduce their biological oxygen demand (BOD) and chemical oxygen demand (COD), control odor, adjust acidity and destroy phenolics. Merichem Company’s patented technology produces a neutral brine effluent stream that can be routed to waste-water treating facilities, evaporation ponds, or waterways. MERICON technology was first licensed in 1988. To date, Merichem has granted 30 operating ...

Optimal Flow

Magcat Catalysts produce up to 15% more syngas through the steam reforming process. Magma form their own catalyst carrier utilizing polymer ceramic technology rather than the traditional pressure method, providing higher intrinsic strength, greater geometric surface area and surface texture. The “Golf Ball” shape and texturing creates a % improvement in active surface area. That combined with enlarged near surface porosity and ENHANCER™ Nickel crystal promoter, delivers ...
