Hydro-conversion of coal hydroliquefaction residue obtained from a 6t/day pilot plant of Shenhua Group in Shanghai was carried out under the hydrotreating condition. The coal hydroliquefaction residue and its product were extracted in sequence with n-hexane, toluene and tetrahydrofuran in a Soxhlet apparatus. The n-hexane soluble fractions increased with the increase of reaction temperature and...

The fast pyrolysis oils produced from proteinaceous biomass, such as pennycress presscake differ significantly from those produced from biomass with mostly lignocellulosic composition. Those from proteinaceous biomass tend to be deoxygenated, contain more nitrogen, be less acidic and be more stable. Because their composition is different, their behavior in and products from upgrading via hydrot...

Although gasoline blending streams exhibit widely varying sulfur concentrations, significant quantities of low-sulfur motor gasoline cannot be manufactured by reallocation of existing components without substantial sacrifices in the useful properties of the remaining fuels having normal sulfur levels. To meet the anticipated demand for low-sulfur unleaded gasoline which may be required for cata...

The pyrolysis of scrap tires is a very attractive strategy to valorize chemically these end-of-life wastes. products this step and any additional one, such as hydrotreating, are relatively complex in nature entangling the understanding limiting viability. In work, we have investigated detail composition tire oil blended with light cycle (from refinery) its hydrotreated using bifunctional NiW/HY...

The main objective of this work is analyzing whether it is possible to develop an empirical correlation for in-line estimation of the sulfur and nitrogen contents of the middle distillates Hydrotreating (HDT) products for control purposes. Correlations are based only on readily available in-line information of specific gravity variation between feedstock and products, without considering any pi...

This article presents the experiments on hydroconversion of mixtures safflower oil (SO) mixed with straight run gas (SRGO) in a different ratio as an alternative to obtain biojet. The research was conducted two stages; first stage mixture SO/SRGO subjected hydrotreating at 350 °C, 380 80 bar, LHSV 1 h−1 and 1.5 h−1, over sulfided NiMo/Al2O3 catalyst, while second which already hydrotreated hydr...
