Embodiment approach

[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each drawing, the same reference numerals are assigned to the same or corresponding parts, and overlapping descriptions will be omitted.

[0050] [Preparation of nickel oxide catalyst]

[0051] figure 1 It is a diagram showing an example of a preparation procedure of a nickel oxide catalyst.

[0052] First, γ-Al 2 o 3 Distilled water was added, and deaeration was performed at 100 mmHg for 2 hours.

[0053] Then, a nickel nitrate aqueous solution manufactured by Wako Pure Chemical Industries, Ltd. was added, followed by stirring for 1 hour.

[0054] Next, it was evaporated to dryness at 80° C. for 2 hours at 200 mmHg, dried at 110° C. overnight, and fired at 500° C. for 2 hours.

[0055] Furthermore, NiO / γ-Al containing 10% by weight of nickel in terms of metallic nickel was prepared. 2 o 3 (hereinafter referred to as "10% by weight NiO / γ-...

Abstract

The invention provides a desulfurization process which can avoid addition of hydrogen to hydrocarbon fuel, is simple than the conventional processes, and can effectively remove sulfur compound in the hydrocarbon fuel. A desulfurization process includes desulfurizing a hydrocarbon fuel using a desulfurizing agent including a support, nickel sulfide on the support, and zinc oxide. The desulfurizing agent is heated to 250 DEG C. or more.

Description

technical field [0001] The invention relates to a desulfurization method and a desulfurizer. Background technique [0002] As a distributed power generation device capable of effectively utilizing energy, a fuel cell cogeneration system (hereinafter simply referred to as a "fuel cell system") with high power generation efficiency and overall efficiency has attracted attention. Many fuel cells, such as phosphoric acid type fuel cells and solid polymer type fuel cells, use hydrogen as a fuel for generating electricity. However, in these fuel cells, a supply device for hydrogen gas required for power generation is generally not yet installed as an infrastructure. As a result, hydrogen needs to be generated at the installation site of the fuel cell system. Therefore, in a conventional fuel cell system, a hydrogen generator is often provided together with the fuel cell. In the hydrogen generation device, for example, a steam reforming method, which is one of hydrogen generatio...
