Description
Summary:[Display omitted] •HDS of SRGO with high content of sulfur and its mixture with CGO were studied.•Four kinetic models of desulfurization with different complexity were compered.•The models are differ in insight into the reactivity of sulfur-containing compounds.•Better prediction give models taking into account the difference in sulfur reactivity. The hydrodesulfurization of straight-run gas oils (SRGO-HS) with high content of sulfur (about 2 wt%) and its mixture with light coker gas oil (CGO) has been studied over CoMo/Al2O3 catalyst using a trickle bed down-flow reactor at the 335–365 °C, H2/HC − 300 Nm3/m3, LHSV − 0.8–2.5 h−1 and 3.5–5.1 MPa. The possibility of ultra-low sulfur diesel (
