processes for producing an annular oxide modeled body, and for heterogeneously catalyzed partial gas phase oxidation of at least one organic compound in a fixed catalytic bed, annular oxide modeled body, and pipe beam reactor.

摘要

A process for producing a ringlike oxidic shaped body by mechanically compacting a pulverulent aggregate introduced into the fill chamber of a die, wherein the outer face of the resulting compact corresponds to that of a frustocone.
