چكيده لاتين :
CO hydrogenation on a cobalt catalyst without inhibitor and support in a fixed bed cylindrical down flow reactor was
studied kinetically. Length of reactor is approximately 10 mm. Tests were performed over the catalyst which contains
Rhenium with the proportion of (Re/Co=0.03). the pressure of reaction set to 23 Bar and temperature range
473.15 - 501.15. catalyst charge with 180 to 250 micrometer particles and 0.3 gr within 0.23 gr of SiC diluent and the
size of 150 micrometer in the reactor in order to obtain the best kinetic model. The best one was selected from the
offered models and activation energy was calculated to be Ea=33/94 kj/mol which had appropriate correlation with the
values mentioned in previous papers.
