Hydrotreatment Followed by Oxidative Desulfurization and Denitrogenation to Attain Low Sulphur and Nitrogen Bitumen Derived Gas Oils

Abstract: To lower the sulphur content below 500 ppm and to increase the quality of bitumen derived heavy oil, a combination of hydrotreating followed by oxidative desulfurization (ODS) and oxidative denitrogenation (ODN) is proposed in this work. NiMo/γ-Al2O3 catalyst was synthesized and used to hydrotreat heavy gas oil (HGO) and light gas oil (LGO) at typical operating conditions of 370–390 °C, 9 MPa, 1–1.5 h−1 space velocity and 600:1 H2 to oil ratio. γ-Alumina and alumina-titania supported Mo, P, Mn and W catalysts … Show more

“…9,10 Currently, NCCs in fuel are usually removed by hydro-denitrication (HDN), which consumes expensive hydrogen and requires high temperature (range from 300 to 400 C) and high-pressure conditions (range from 30 to 130 atmospheres). 11,12 The process is not economical. Photocatalysis technology is a kind of technology with low energy consumption and mild conditions, which has attracted signicant attention.…”

“…S11 in the ESI †] for ODS is based upon previous literature reports. 110,111 The reaction is expected to proceed via the coordination of TBHP to the catalyst with a nucleophilic attack to polarize the terminal Mo-O bond, thereby enhancing the electrophilicity of peroxide oxygen of the oxidant. In the second step, the oxidation cycle is initiated by a nucleophilic attack of sulphur in DBT on electropositive oxygen to form DBT sulfoxide (DBTO).…”
