Improvements in and relating to the production of coke

Patent ·
OSTI ID:7359830
;

A process is described for the production of coke which comprises extracting coal at an elevated temperature with a suitable solvent, filtering undissolved material from the extract, concentrating the extract and thereafter coking the concentrated extract while recovering the solvent for recirculation characterised in that prior to digestion of the coal the solvent is subjected to coking under conditions comparable with the conditions under which the coal solution is subjected to coking until coking of all the cokable components in the solvent is substantially complete.
