英文摘要The effects of copper and potassium on the activity and selectivity of coprecipitated fe-mn/sio, catalysts for fischer-tropsch (f-t) synthesis were studied in a slurry phase continuous stirred tank reactor. the reduction and adsorption behaviors of the catalysts were investigated using temperature programmed reduction/temperature programmed desorption (tpr/tpd) methods. it was found that copper improves the reduction of the catalyst in h, or co. potassium improves the reduction of the catalyst in co, whereas it suppresses the reduction of the catalyst in h, copper enhances the h, adsorption, whereas potassium has no influence on the h-2 adsorption. in the f-t synthesis reaction, copper shortens the induction period required for reaching the steady state activity, whereas potassium prolongs the induction period. the potassium promoter increases the activity and decreases the selectivity of methane. the promotion effects of cu and k on the activity and selectivity is more obvious than that of cu, that is, the activity is higher and the methane selectivity is lower on the doubly promoted catalyst.
