摘要：
Information on the wettability of a bio-coke substrate is of great value in assessing its possible use as a potential raw material for carbon anode production. In this study, the interaction mechanisms of a coal tar pitch with six bio-coke substrates were studied at a temperature of 170 degrees C, a typical industrial value for coke-pitch mixing, using a sessile-drop test. Three bio-cokes were produced from different bio-materials by pyrolyzing them to 426 degrees C, and the other three by further calcining them to 1200 degrees C. Different techniques were used to analyze the structural and chemical characteristics of the six bio-cokes. The results show that the heat treatment temperature has a significant influence on the chemical properties of bio-cokes and the wettability of pitch/bio-coke systems. The possibility of partial replacement of petroleum coke by bio-coke is discussed from the point view of the suitability of its structure and its wettability. (C) 2015 Elsevier B.V.
