APPLICATIONS AND MARKETS
The SCHWING fluidized bed process technology is predestined for gas-solids reactions. As a core application, this technology is used in the area of surface modification of innovative, even nano-scale, powders. Especially the usage options for different reaction gases (air, N2, H2, NH3, CO2, O2, Ar, H2O(g), etc.) primarily in the temperature range up to 1100 °C offer a variety of new applications.
Sample applications: Fluidized bed process technique
Many metallic oxides, catalysts, hydroxides, silicates, salts, sulfates, carbon blacks, pigments and graphites are roasted, calcined, reduced, oxidized, activated, passivated, chlorinated, dried, tempered, etc. using fluidized bed processing systems but gases can also be changed on powders through the fluidized bed.
Typical products and applications are:
Production of carbon modifications → Carbonizing / Engineering material, batteries
Graphite, Soot → Pigments / Surface modifications / Batteries, tire industry
Active carbon → Activation / Desorption / Water plants, chemical dry-cleaning, clothing
Titanium dioxide → Tempering / Coating / Pigment production, paints and varnishes, crèmes
Catalyst → Recycling / Oxidation / Reduction
Quartz sand → Deactivation of binding agents / foundry sand
Silicon → Calcining / Surface modifications / Recycling cutting waste, solar cells, silanes
Silicon dioxide → Silicic acid / Optical waveguides, data transmission
Salts → Carbonates / Fuel cells, glass, ceramics, enamel industry
Metal oxides → Tempering / electrical technology, batteries, catalysts
Gas/Gas reactions → catalytic / Solar industry, acid production
Carbohydrate → native / modified starch
