Coke including additives that are accumulated at the yield points or in the regions surrounded by the yield points. For homogeneous distribution, the additives are continuously dosed into the delayed coker during the filling time. The dosing can be carried out by powdery blowing with an inert gas (nitrogen) or also distributed in a slurry consisting of the reaction components and a partial flow of the coker feed (vacuum resid, pytar, decant oil or coal-tar distillates). According to an advantageous form of embodiment, the additives may optionally have a diameter of between 0.05 mm and 5 mm, preferably between 1 mm and 3 mm. Advantageously, the additives can be selected from at least one of acetylene coke, fluid coke, flexi coke, shot coke, carbon black, non-graphitisable carbons (chars), non-graphitic anthracite, silicon carbide, titanium carbide, titanium diboride or mixtures thereof.

Coke with additives

A method for the production of polygranular graphite bodies including the step of provisioning a mixture including a high-temperature treated anthracite having a high vitrinite content and a petroleum-based needle coke and/or a pitch-based needle coke, and provisioning at least one binder coke precursor. The method also includes the steps of forming a green body from the mixture from the provisioning step, and carbonizing and graphitizing the green body.
