Catalytic reforming of the 85?140� C fraction of Lelyakov petroleum

Abstract

1. We have studied the material balance and composition of the products of catalytic reforming of the 85140°C fraction of Lelyakov petroleum. 2. It has been shown that in the temperature range 470–500°C, at a volumetric flow rate of the feedstock of 1.5 h−1, and at a pressure of 35 atm the yields of the liquid reforming products and the 62–150°C target fraction change by only 3–5 wt. %. Whereas the yield of the liquid products falls with increasing temperature, that of the 62–150°C target fraction increases. 3. It has been established that under the investigated conditions an increase in the process temperature from 470 to 500°C is accompanied by an increase in the overall yield of aromatic hydrocarbons (benzene, toluene, ethylbenzene, and xylenes), but the ratio of the individual aromatic hydrocarbons in the catalysates remains virtually constant.
