Abstract
A technique for measuring the coefficient of thermal expansion of calcined petroleum coke. This technique involves pressing a pellet of calcined coke to determine the coefficient of thermal expansion. It has the advantage of eliminating the graphitization and machining steps resulting in reduced manpower and turnaround time and requires less sample which allows CTE determination of laboratory scale cokers. Results show good correlation between this technique and traditional extrusion techniques.
