Studies of the Efficiency of Diesel Isodeparaffinization over a Zeolite-Containing Nickel-Molybdenum Catalyst

Abstract

A new catalyst GIP-14 was developed for isodeparaffinization of diesel fuels. The catalyst was prepared based on a mixture of zeolites with different pore structures and aperture size using transition metals Ni and Mo as hydrogenating agents. The stability of the catalyst operation was studied. In the process achieved at 305–310 °C and feed flow rate 3 h-1, the yield of diesel fuel was 92–93 wt.% while the cold filter plugging point was below –38 °C. The obtained diesel fuel sample was certified in terms of the State Standard 55475-2013. The developed catalyst and its imported analogue were compared to conclude that GIP-14 is up to the world level and provides the production of diesel fuel with the required low-temperature characteristics under milder conditions (300 °C against 320–325 °C with the imported catalyst) and at a higher feed flow rate (3 h–1 against 2 h–1). The industrial production of the catalyst GIP-14 is to be arranged in 2017.
