Title:
タール様不純物含有ガスの改質方法
Document Type and Number:
Japanese Patent JP5606064
Kind Code:
B2
Abstract:
The invention relates to a method of reforming a gas containing tarry impurities, such as the gasification gas obtained by gasifying a fuel. In the method, oxygen or an oxygenous gas (10) is added to a gas flow (8), after which the gas is brought into contact with a solid catalyst (11, 12) at a high temperature. According to the invention, the reformation takes place in stages so that, in the first pre-reforming stage, the gas is brought into contact with a zirconium-based catalyst (11), such as zirconium oxide, for example, and, in the next stage, with a metal catalyst (12), such as metallic nickel. The two-stage reformation is used for preventing the deactivation of the metal catalyst and the formation of carbon deposits in the reforming reactor. The invention also includes the use of the zirconium compound in pre-reforming the tar-bearing gas to achieve the said goals.
