Making use of the precious metal based catalyst, the method of making the tar content in the gas decrease which is derived from gasification process with the catalyst

摘要

As for this invention, at least contact with the portion of the gas which is obtained from gasification process in regard to the method in order to make the tar content in the gas decrease which it occurs as a result of thermochemical gasification process of the starting substance which contains carbon, and the catalyst which contains the precious metal is included. This invention the gas which is processed, before making contact with the catalyst which contains the precious metal, features that it does not make contact with the zirconium catalyst. The catalyst which contains the precious metal includes a kind of is selected precious metal at least from the group which consists of Pt, Pd, Rh, Ir, Os, Ru and Re. However, in case of Pt, the aforementioned element is used at least combining with kind of further precious metal or Ni. Selective figure It is not
