Abstract
Laboratory calcinings were performed to determine the effects on coke structure and properties when calcined at different temperatures. The temperature range was from 1200°C to 1500°C with emphasis at temperatures in close proximity to what is considered typical of commercial calcining temperature. The five cokes selected represented a wide range of properties from low sulfur cokes at 0.78% to high sulfur cokes at 4.2% and from anisotropic to isotropic in structure. In the initial “Part I” paper which was presented at the 1993 AIME Light Metals, the focus was on the bulk density and those properties often associated with measurements used to quantify and control degree of calcining including real density, electrical resistivity, and the crystalline features Lc and d-spacing. This “Part II” paper will discuss various property relationships to temperature including mercury apparent density, porosity, nitrogen, hydrogen, sulfur and metals, coefficient of thermal expansion, Hardgrove Grindability, and air and carboxy reactivity.
