Sažetak
One of the new requirements of catalytic reforming is thereduction of gasoline vapour pressure in order to lower thehydrocarbon emission. Another requirement is the elimination ofhighly toxic aromatic hydrocarbons, pacticularly benzene. Sincethe reformate is major highoctane-blending component, it isimportant to choose such process parameters that will ensure thelowest possible content of aromatics. Therefore, the activity of two commercial catalysts, thehight pressure R-16 G and low pressure R-62, was tested in apilot plant fixed-bed reactor at various temperatures, 490-525 C, and various space times, 0.18-0.37 h. It was found that the low pressure catalyst R-62 is moreactive for the aromatization reactions than the hight pressurecatalyst R-16 G. This can be attributed to the favourablereaction conditions (low pressure). The results also proved thatthe naphthenes of six carbon atoms in a molecule are the majorsource of aromatic hydrocarbons while the reactions of naphthenedehydroisomerization and paraffin dehydrocyclization contributeto a smaller extent.
