Fuzzy grey relational analysis for influence factors on the quality of calcined petroleum coke

Abstract

Real density and powder resistivity are key indicators for the quality of calcined petroleum coke (CPC). They are closely related to calcining parameters in shaft calciner. Fuzzy grey relational analysis was proposed to evaluate the effects of various factors (discharge rate per pot (DR), flue wall temperature of layers 2 (T2) and 8 (T8), volatiles (V), ash (A) and sulfur content (S) of green petroleum coke) on the quality of CPC. Results showed that by order of influence degree (most to least) to the real density, the factors were ranked as T2, V, DR, T8, A, and S, and for the powder resistivity, they were ranked as V, T2, DR, T8, and S.
