Production method of tar-containing gas recovery catalyst, tar recovery method, and tar-containing gas recovery catalyst regeneration method

摘要

A precipitate is produced using a precipitant in a solution containing nickel and magnesium, the precipitate is dried and fired to produce an oxide of nickel and magnesium, the oxide is added to and mixed with alumina and water or with an alumina sol, and the mixture is least dried and fired to produce a tar reforming catalyst for reforming and gasifying pyrolysis tar of a carbonaceous raw material.
