چکیده
|
The influence of sio2 and al2o3 binders on the catalyst performance and products selectivity of the precipitated fe-cu-k catalyst physically mixtured with hzsm-5 was studied in a fixed bed tubular reactor. the iron catalyst was mixed with hzsm-5 zeolite and shaped to cylinders form by alumina and or silica as a binder for increasing the mechanical strength of bifunctional catalyst. the catalyst activity was tested underreaction condition, p=17 bar, t=290 °c , h2/co=1 and ghsv= 3.07 nl.h-1.g.fe-1. the results showed that the catalyst activity for fischer – tropsch and water gas shift reactions for silica binders is lower than alumina and secondary reactions in the presence of alumina is higher .
