The present invention relates to a sulphur-free odorizing composition to be added into liquefied petroleum gas (LPG) in order to allow the user to sense any leakage in case of LPG leakages which might occur in the area of utilization.

A diesel fuel substitute composition includes an alcohol, an acetal, and an additive comprising a component selected from the group consisting of C.sub.3-8 dialkyl ethers, alkylated phenols, RNO.sub.2, and combinations thereof. A method for forming the diesel fuel substitute is also provided.

An aerosol generating article and an aerosol generating system, which include a composite heat source, are provided. An aerosol generating article includes: a first portion including a composite heat source; a second portion adjacent to the first portion and including at least one of an aerosol generating material and a tobacco material; a third portion including a cooling material; and a fourth portion including a filter material, wherein the first portion, the second portion, the third portion, and the fourth portion are sequentially arranged along a longitudinal direction of the aerosol generating article.

A fuel composition for combustion according to claim 1, the fuel composition comprising a hydrocarbon-based fuel and magnetite material comprising magnetite. The magnetite material is in the form of powder with a size range from 1 nm-1 mm. The magnetite material is 0.1-80% wt of the fuel composition. The magnetite material comprises at least 40% magnetite (Fe.sub.3O.sub.4) and has at least 25% Fe (iron).

The new fuel conceived for diesel engines is formulated using one part of standard diesel fuel and two groups of components with different characteristic rating. The first group is composed by reformulated chemicals, while the second group in made by a blend of vegetal oils properly balanced.

The fuel obtained with this formulation has a better thermodynamic performance and allows an appreciable reduction of carbon dioxide (CO.sub.2) and particulate matter (PT) output which are, respectively, approximately 50% and 60% lower

A supported catalyst for reducing CO.sub.2 is provided. The supported catalyst includes a plurality of support particles; and a plurality of catalyst particles disposed over each support particle. Characteristically, the catalyst particles has formula PdH.sub.x/C wherein x is 0.3 to 0.7. Methods for making the support particles and using the support particles to reduce carbon dioxide are also provided.

A fuel additive having one or more industrial and/or mining waste components, the one or more industrial waste components including one or more components generated by alumina and/or shale oil production. Also described are methods of making and methods of using the fuel additive.
