Abstract
Authors propose a method for modifying catalysts based on a high-silica zeolite of the ZSM-5 type using Ni nanopowder to improve catalysts for the refining of straight-run gasoline fractions.
The proposed method involves solid-phase mechanical mixing with Ni nanopowder. It is more environmentally friendly than conventional methods of impregnation and ion exchange. The developed Ni-containing zeolite catalysts allow the investigators to lower the temperature for the refining of low-octane gasoline fractions by 20–40°C and to increase the yield of target products containing high amounts of high-octane components, i.e., isoalkanes. The acidic and catalytic properties of high-silica zeolites containing different amounts of Ni nanopowder were studied. The activity of the catalyst systems in the conversion of straight-run gasoline fractions of petroleum was analyzed. The optimum catalyst composition and the process conditions for obtaining a maximum yield of the target product, i.e., high-octane gasoline, are determined.
