Embodiment 1

[0034] Embodiment 1 (comparison)

[0035] At full production scale, 7 parts of calcium aluminate binder, 2.2 parts of basic copper carbonate and 2.7 parts of basic nickel carbonate were added to 100 parts by weight of particulate zinc support material. The resulting powder was thoroughly mixed and then granulated using an orbital planetary mixer. The resulting particles were then sieved and calcined at 300° C. on-size fractions (2.8-4.75 mm) to form mixed oxides. The loadings of NiO and CuO in the finished product were both 1.5% by weight.

Embodiment 2

[0036] Embodiment 2 (comparison)

[0037] At laboratory scale, calcium aluminate binder (0.42 kg), basic copper carbonate (0.13 kg) and basic nickel carbonate (0.16 kg) were added to the particulate zinc support precursor (6.00 kg). The resulting powder was mixed thoroughly and then granulated using a laboratory scale orbital planetary mixer. The resulting particles were then sieved and calcined at 300° C. in fractions (2.8-4.75 mm) with the desired size to form mixed oxides. The loadings of NiO and CuO in the finished product were both 1.5% by weight.

Embodiment 3

[0039] The procedure of Example 2 was repeated except that 0.034 kg of sodium carbonate was also added to the powder mixture. This provides 0.5 wt% Na in the calcined product 2 O load.

Abstract

A particulate desulphurisation material is described comprising 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 desulphurisation material is also described comprising the steps: (i)contacting a nickel compound with a particulate zinc support material and an alkali metal compound to form an alkali-doped composition, (ii)shaping the alkali-doped composition, and (iii)drying, calcining, and optionally reducing the resulting material. The desulphurisation material may be used to desulphurise hydrocarbon gas streams with reduced levels ofhydrocarbon hydrogenolysis.

Description

technical field [0001] The present invention relates to desulfurization materials, in particular desulfurization materials comprising nickel. Background technique [0002] The hydrocarbon feed to be used for synthesis gas production must first be desulfurized in order to protect sensitive downstream catalysts from deactivation. Sulfur removal is conventionally performed using a combination of hydrodesulfurization (HDS) catalysts (typically based on CoMo or NiMo catalysts) and zinc oxide-based absorbents. In this process, the HDS catalyst converts any organic sulfur species in the feed to hydrogen sulfide, which can then be removed by reaction with ZnO. In order for the hydrodesulfurization reaction to proceed, hydrogen must be present in the feed. As an alternative to the two-stage process described above, it is also possible to use a single material that combines hydrodesulfurization activity and hydrogen sulfide absorption capacity.
