PCT No. PCT/EP85/00110 Sec. 371 Date Jan. 9, 1986 Sec. 102(e) Date Jan. 9, 1986 PCT Filed Mar. 16, 1985 PCT Pub. No. WO85/04347 PCT Pub. Date Oct. 10, 1985.The granulates of active coke produced from pit coal have an inactive abrasion-proof core based on coal or a ceramic material, as well as an envelope based on active coke particles adhering to the core. Various processes for producing said granulates are disclosed. In one embodiment, a ground coal covering is applied to the core before activation; another embodiment provides for the application of a covering based on coke particles already activated. In a third embodiment, on the inactive core based on swollen and burned material there is first provided an intermediary layer based on a material which volatilizes partly during the carbonizing treatment in order to compensate for the expansion differences of the core and of the envelope. |
