A process for desulphurizing hydrocarbons includes passing a mixture of hydrocarbon and hydrogen over a hydrodesulphurization catalyst to convert organosulphur compounds present in the hydrocarbon to hydrogen sulphide, passing the resulting mixture over a hydrogen sulphide sorbent including zinc oxide to reduce the hydrogen sulphide content of the mixture, and passing the hydrogen sulphide-depleted mixture over a further desulphurization material. The further desulphurization material includes one or more nickel compounds, a zinc oxide support material, and optionally one or more promoter metal compounds of iron, cobalt, copper and precious metals. The desulphurization material has a nickel content in the range 0.3 to 20% by weight and a promoter metal compound content in the range 0 to 10% by weight.

Desulphurisation process

A process for the preparation of a desulfurization material includes:

Preparation of desulphurisation materials

A particulate desulfurization material includes one or more nickel compounds, a zinc oxide support material, and one or more alkali metal compounds wherein the nickel content of the material is in the range 0.3 to 10% by weight and the alkali metal content of the material is in the range 0.2 to 10% by weight. A method of making the desulfurization material includes the steps: The desulfurization material may be used to desulfurize hydrocarbon gas streams with reduced levels of hydrocarbon hydrogenolysis.

Desulfurization materials

The invention deals with a microporous crystalline material, with a characteristic X-ray diffractogram, comprised of oxygen tetrahedra and a metal (T and T ) with the possibility of introducing surface acidity produced by the substitution in the lattice of some T cations by T cations, which gives rise to a structural charge deficiency that may be compensated by protons, Br&ouml;nsted acidity, and/or high ratio radium charge cations, Lewis acidity; and the obtaining method thereof, based on the preparation of a gel, its hydrothermal treatment under controlled conditions and the treatment of the resulting laminar material with a solution of an organic compound, a swollen material being obtained, which is subjected to a treatment for the formation of interlaminar pillars of polymeric oxides, obtaining a pillared material that maintains the separation between the sheets, even after calcination.

Acid oxide with micro and mesoporous characteristics: ITQ-36

The invention concerns a microporous oxide material ITQ6, with a characteristic X-ray diffraction pattern, and surface areas for which microporous surface area may be of at least 20 m /g the external surface area may be at least 350 m /g and the total surface area may be at least 400 m /g. It may be made via preparation of gel, its hydrothermal treatment, and the treatment of the resulting material with a swelling solution followed by at least partial delamination e.g., by mechanical agitation or ultrasonics. The final oxide material is calcined and, in its acid form or combined with metals, especially noble metals, is useful as catalyst for the isomerization of n-butene to isobutene, or in dewaxing and isodewaxing processes and as a catalytic cracking catalyst or as an additive in FCC catalysts.
