Accelerated deactivation ofCo/A1203 catalysts in Fischer-Tropsch synthesis and the
effect ofRe and Ru as the catalytic promoters are reported. 15wt% Co/A120 3 catalyst and 1wt% Ru
and 1.4wt% Re promoted cobalt catalysts have been formulated and extensively characterized The
deactivation ofthe unpromoted cobalt catalyst and those promoted with Re and Ru were studied by
accelerated method at 26(fC. Different sources of deactivation were identified. The amount of
activity recovery after regeneration at the conditions of low temperature treatment at 26(fC and
high temperature treatment at 40(fC for the used promoted and unpromoted catalysts were
detrmined. It was revealed that promoted catalyst deactivated faster than unpromoted ones. High
temperature H2 treatment restored the catalytic activity ofthe catalysts more than 97.5%.
