Abstract
A cobalt-based Fischer-Tropsch catalyst, after 125 days of continuous synthesis, was found to have retained excessive amounts of synthesis p roducts and was not pyroforic in air. Upon resuming synthesis, unusual reactions were observed for about 20 h. Carbon monoxide conversion wa s quantitative. The major product was methane, with a fairly flat dist ribution of paraffins and isoparaffins. Excessive end gas volumes and the presence of isoparaffins suggest that hydrocracking of the waxes d eposited in the catalyst pores may have been the major reaction. Later , ''normal'' synthesis occurred. Catalyst activity measurements indica ted a successful regeneration by the events.
