Improvement of catalysts for upgrading naphtha fractions
Abstract
The authors proposed a method of modifying a catalyst based on high-silica zeolite ZSM-5 type by nanosized Ni-powder to improve catalysts for straightrun gasoline fractions upgrading. The proposed method of solid-phase mechanical mixture with Ni-nanopowder more environmentally friendly than traditional impregnation or ion exchange, and developed Ni-containing zeolite catalysts can reduce low-octane gasoline fractions upgrade process temperature on 20–40 °C, increase the desired product yield with high content of high-octane components - isoalkanes. We have studied the acidic and catalytic properties of high silica zeolite containing different amounts of nano-sized Ni-powder. The activity of catalytic systems is investigated in the conversion of virgin petrol fractions of oil. There is determining the optimal composition of the catalyst and process conditions for obtaining maximum yield of target product - high-octane gasoline.
