Abstract

The present invention provides a method for producing a highly active catalyst for reforming tar-containing gas used to treat crude gas for chemical energy conversion consisting of converting to a fuel composition consisting mainly of methane, hydrogen and the like, by utilizing sensible heat possessed by crude gas generated during thermal decomposition of carbonaceous raw materials, and using the high chemical reaction activity of high-temperature tar contained in and incidental to the crude gas to convert the tar to light hydrocarbons in the presence of a catalyst; a tar reforming method; and, a method for regenerating a catalyst for reforming tar-containing gas.
