    Abstract: Aromatic p -compounds of the formula Mea(R)x(CO)y, where Me is a group VIA, VIIA or VIII metal, a is from 1 to 4, R is a five or six membered aromatic p -system, x is from 1 to 5 and y is from 0 to 9, are used as catalysts in the refining of hydrocarbon mixtures with an oxygen-containing gas or oxygen-liberating compound which is soluble in hydrocarbons. Hydrocarbon mixtures specified are gasolines, Diesel oils, fuel oils and lubricating oils. The oxy-compound treatment may be used to effect oxidation of sulphur compounds or polymerization, condensation or resinification of nitrogen compounds, e.g. pyrrole, oxygen compounds, e.g. coumarone or indene, olefines and diolefines. The oxygen-containing gas or compound may be air or benzoyl, diacetyl, dilauroyl, dibenzoyl, di-p-toluoyl or di-t-butyl peroxide. Gasolines containing peroxides such as thermal reformates or cracking products which have stood in the air can also be used to provide the oxygen. In the catalyst Me may be manganese, nickel, iron, cobalt, molybdenum or chromium and R may be benzene, toluene, xylene, mesitylene, hexamethylbenzene, mono- or di-ethyl benzene, propylbenzene, diphenyl, polyphenyl methane or ethane, tetrahydrobenzene, anthracene, phenanthrene, pyrene, benzpyrene, coronene, cyclopentadienyl, phenyl- or mono- or di-methyl or ethyl-cyclopentadienyl or fluorene. The catalyst may be subsequently decomposed by heating or irradiation with light, e.g. from mercury vapour lamps. The refined product may be after-treated with active carbon or bleaching earths and filtration or distillation. In examples the catalysts used are dimesitylene chromium, dicyclopentadienyl nickel and cyclopentadienyl manganese tricarbonyl.ALSO:Aromatic p -compounds, MaRx(CO)y where M is a Group VIa, VIIa or VIII metal, a is 1 to 4, R is a five or six membered aromatic p system, x is 1 to 5 and y is 0 to 9 are used as catalysts in refining hydrocarbons (see Group III). M may be magnesia, nickel, iron, cobalt, molybdenum or chromium and R may be benzene; toluene; xylene; mesitylene; hexamethyl-, mono- or diethyl- or propyl-benzene; diphenyl; polyphenyl methane or ethane; tetrahydrobenzene; anthracene; phenanthrene; pyrene; benzpyrene; coronene; cyclopentadienyl; phenyl- or mono- or dimethyl- or ethylcyclopentadienyl; or fluorene. Specific compounds used in examples are dimesitylene chromium, dicylopentadienyl nickel and cyclopentadienyl manganese tricarbonyl of formulae:

    Abstract: The cetane numbers of diesel fuels are improved by the addition of hydroaromatic nitrates, e.g. cyclohexyl nitrate, which have been stabilized with N-alkylated monoalkanolamines.ALSO:Hydroaromatic nitrates are stabilized by the addition of up to 10 weight per cent N-alkylated monoalkanolamine. In examples, cyclohexyl nitrate is stabilized with Me2NC2H4OH, Et2NC2H4OH, Pr2NC2H4OH, MeEtNC2H4OH, and n- and iso-Me2NC3H6OH.
