Abstract
Granulated products are provided and include carbonaceous particles and a carbonized agent or binder. The agent or binder is preferably a synthetic resin, pitch component, or mixture thereof. Packing materials for packing columns used in chromatographic separations are also provided as are methods of chromatographic separation using the materials. In addition, methods are provided to provide a variety of different types of carbonaceous products. A variety of chemical groups can be, prior to heat-treatment and/or thereafter, attached to the granules to form modified granules.
Claims1
A granulated carbonaceous product comprising carbonaceous particles and at least one uncarbonized binder, produced by the process of:
- mixing the carbonaceous particles with at least one binder and at least one solvent to form a mixture;
- granulating said mixture to form granules;
- and
- heating said granules at a temperature below the carbonaceous temperature of the binder to form said granulated carbonaceous product.
