    Abstract: Methods are provided for determining the compatibility of various grades of fuel oils, as well as methods for modifying fuel oils to improve compatibility and improved compatibility compositions. It has been discovered that the toluene equivalent solvation power of a blend of fuel oils does not vary in a straightforward manner with respect to the toluene equivalent solvation power of the individual blend components. Instead, it has been determined that the asphaltene content of the individual components can also influence the toluene equivalent solvation power of the final blend. Based on this discovery, methods are provided that can allow for modification of one or more components of a potential fuel oil blend. This can reduce and/or minimize the likelihood of asphaltene precipitation when a fuel oil blend is formed.

    Abstract: Composition which can be used in particular as odorant for a gaseous fuel, more particularly natural gas, comprising: from 0.1 to 49.9 parts by weight of at least one alkyl sulphide (I) of formula: R1—S—R2  in which R1 and R2, which are identical or different, represent: an alkyl radical comprising from 1 to 4 carbon atoms; or R1 and R2, taken with the sulphur atom to which they are attached, represent a saturated or unsaturated ring comprising from 3 to 5 carbon atoms which is optionally substituted by a C1-C4 alkyl or C1-C4 alkenyl radical; from 50 to 99.8 parts by weight of at least two alkyl acrylates (II), the alkyl radicals of which comprise from 1 to 12 carbon atoms, preferably from 1 to 8; from 0.001 to 0.1 part by weight of at least one compound (III) which inhibits the polymerization of the alkyl acrylates (II).
