Abstract

PURPOSE: To obtain a carbon catalyst for SO3/SO2 conversion having high SO3/SO2 converting activity by treating a carbon material with an oxidizing acid followed by heat treatment at a predetermined temp. in an inert gas atmosphere.
CONSTITUTION: A carbon material such as carbon black is treated with an oxidizing acid such as nitric acid-sulfuric acid mixture, nitric acid or hot concd. sulfuric acid. The acid treated material is preferably washed with pure water or the like and dried at about 150°C for about 3hr in an inert gas atmosphere. The dried material is then activated by heating at 300W700°C in an inert gas atmosphere. The resulting carbon material has high SO3/SO2 converting activity, high flame resistance, that is, high endurance and a long life.
