Electrode coke from coal via solvent extraction
- Univ. of Kentucky, Lexington, KY (United States). Center for Applied Energy Research
The development of a process to make high quality coke from coal for use in the manufacture of artificial graphite electrodes will be described. The process uses solvent extraction with a non-hydrogen donor recycle solvent; the effects of various process variables upon the quality of the final graphite were studied. Following laboratory work a 1/2 ton per day pilot was built which included a pair of delayed cokers, each with a capacity of 300 kg. After studying various chemical engineering aspects the pilot plant was run as a production unit in order to accumulate enough coke for the semi-commercial manufacture of graphite electrodes of 300 mm diameter. These electrodes were then tested in a 25 ton commercial arc steel furnace.
