Sažetak
The influence of the operating parameters on the activity oftwo commercial Pt-Re/Al2O3 catalyst (R-62 and R-16G), onhydrocracking and isomerization reactions in naphtha reformingwas investigated. The reactions were performed in a fixed-bedreactor of 26 mm i.d. at space velocity from 2.7 to 5.4 1/h andat temperatures of 505 and 525 C. It has been found that the yield of liquid product at bothtemperatures increases with increasing space velosity but R- 62catalyst is more active than the R-16G. This means that R-16Gactivity is higher for hydrocracking reactions when the gaseousproducts are formed. It should also be noted that higher activityof R-16G for hydrocracking is not only influenced by the acidsites of alumina but also by the higher operating pressure (27bar). Catalyst R-62 has shown higher activity in dehydroisomerizationreactions of CyC5 naphthenes into aromatic hydrocarbons than theR-16G. This directly influences the quality of the products.
