Batch experiments as well as results from LC-Fining catalytic upgrading of coal extracts indicate deactivation of the Shell 324 Ni/Mo catalyst in the presence of solvent refined coal (SRC). At increased levels of SRC loading, deactivation increases. The chief cause of catalyst deactivation appears to be coking. The Shell 324 catalyst can be substantially regenerated after the upgrading reaction by medium temperature ashing followed by presulfiding.
