Products composition catalytic cracking via aerosol nanocatalysis for modified Si/Zr-catalyst
The analysis of experimental studies of the process of catalytic cracking of vacuum gasoil in conditions of the aerosol nanocatalysis technology for a new sample of the Si/Zr-catalyst is given. The influence of the process temperature and the frequency of mechanochemical activation (MCA) of the catalyst on the yield of cracking products — gasoline and diesel fractions is determined. The process of catalytic cracking of vacuum gasoil in the investigated conditions proceeds with high light-products selectivity and primary formation of the diesel fraction (DF). The maximum yield of the DF was 60 %. The frequency of MCA of 6 Hz leads to the maximum of the formation of the gasoline fraction (GF) at temperatures of 350, 400, 450, 500 °C and the frequency of 6,5 Hz is optimal for the maximum obtaining of the product with a maximum of 300 and 550 °C. The temperature of the beginning of the catalytic reaction is determined. The temperature of ignition of the studied sample of the Si/Zr-catalyst in conditions of AnC was 350 °C and at the increase of the frequency of MCA decreased to 300 °C.
