Hydrorefining of catalytic naphtha cuts

A polyfunctional catalyst for hydrorefining of the catalytic naphtha cut with a high olefin content is proposed. This catalyst induces isomerization and hydrogenation of olefins on contact with the feedstock with formation of isoparaffins, isomerization of n-paraffins, hydrotreating to remove sulfur, and other processes. The naphtha obtained satisfies the Euro-4 standard (2005) with respect to quality. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 5, pp. 35–3 6, September–October, 2007.

Combined isomerization of overhead cuts of straight-run naphtha and reformate

Technology was developed for combined isomerization of IBP-85°C overhead cuts of straight-run naphtha and reformate to reduce the benzene content in automotive gasolines. In comparison to the traditional technology, this technology ensures a benzene content below 0.7% and a 1–2-point increase in the octane number (ON) of commercial gasolines. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 4, pp. 5–8, July–August, 2008.
