METHOD FOR THE PRODUCTION OF ANNULAR-SHAPED SUPER CATALYSTS

摘要

The invention relates to a method for the production of annular-shaped super catalysts by thermally treating annular-shaped super precursor moulded bodies. The lateral pressure resistance of the annular shaped super catalyst precursor moulded body is > 12 N and < 23 N. The invention also relates to the resulting annular-shaped super catalysts having a specific pore structure and to the use of said annular- shaped super catalysts for gas- phase catalytic partial oxidative production of (meth)acroleine.
