One of the most important properties of cokes as fillers for electrode production, in particular in anode pastes for self-baking anodes and electrode masses for baked anodes in aluminum cells, is their reactivity. It largely determines the properties of baked anodes, influences their consumption during electrolysis, and determines the burnoff loss of coke material during calcination. Since the consumption of coke in these processes should be regarded as the result of combustion, problems of reduction of unproductive losses of calcined material cannot be solved successfully without studies of development of the reactive properties of cokes during heat treatment. The main type of coke used at present for anode production is petroleum cokes from delayed coking units (DCU coke), produced by the Ministry of the Petrochemical industry of the USSR in accordance with GOST 22898-78. To confer the necessary technical properties (definite electrical conductivity and density) on the coke, it is calcined at 1200-1300/sup 0/. In the present work the authors studied the reactivity of low-sulfur DCU cokes.
