Adding value to coal chemicals in high-tech applications and green technologies
Coal chemicals have an extremely high carbon content, and their molecular structure makes them ideal materials to be transformed into pure carbon and graphite.
This is particularly useful in applications where metals cannot meet the high-temperature or chemical-resistance requirements. In these specific conditions carbon will resist.
Many compounds containing pure carbon can be found in high-tech applications: high temperature smelting, carbon reinforced disc brakes, electrodes in Li-ion batteries and brushes for electric motors.
Different crystals, but still carbon…
Many different applications for the same element: carbon.
And as many different processes to convert coal chemicals to carbon.
Each process results in a different crystal structure and properties of the carbon components:
- the rigid hexagonal planes of graphene and graphite
- partly graphitic structures of anodes for aluminium
- to the spherical agglomerates for carbon black
PAH : unique heat-polymerisation process
- Liquid to solid conversion, with crystalline structure
- Final structure, after long high-temperature reaction = graphite.
- Intermediate = smaller graphitised patches/crystallites
