Abstract:
This report describes the design, construction, and operation of an experimental delayed coking unit for the conversion of petroleum residues to coke for use as the filler component in graphite for aerospace applications. The effect of changes in operating conditions of the experimental coker, e.g., time-temperature, pressure, and recycle ratio was investigated with respect to the physical properties of graphitized extruded and molded samples. Four basic charge stocks were studied vacuum residuum, slurry decant oil, thermal tar, and a low sulfur thermal tar. Variations in raw coke bulk density are reported in addition, data concerning kerosene density, ash, and sulfur content of the 1000C calcined cokes are also included. Changes in bulk density, weight, and volume of the extruded and molded test samples resulting from the processing steps of baking and graphitizing are reported. The CTE coefficient of thermal expansion, specific resistance, and flexural strength of the graphitized molded plugs in both the with- and across-grain directions are reported as well as the same properties for the with-grain direction of extruded rods.
