CONFORMED STRUCTURES OF OXIDIZATION CATALYSTS FOR THE PRODUCTION OF MALEIC ANHYDRIDE.

摘要

CONFORMED OXIDIZING CATALYTIC STRUCTURES CONTAINING A CATALYTIC MATERIAL CONSISTING OF MIXED OXIDES OF VANADIUM AND PHOSPHORUS THAT ARE USEFUL FOR THE PRODUCTION OF MALEIC ANHYDRIDE, NAROUL AROTIC, IN NAROUL AROTIC NORTHERN AROID STEAM WITH MOLECULAR OXYGEN OR A GAS CONTAINING MOLECULAR OXYGEN. SUCH STRUCTURES ARE CHARACTERIZED BECAUSE THEY PRESENT (A) A GEOMETRIC VOLUME OF 30 PERCENT APPROXIMATELY TO 90 PERCENT APPROXIMATELY OF THE PRESENTED BY THE FREE GEOMETRIC FORM WITHOUT HOLLOW SPACES BY GEOMETRICAL SURFACE AREA AT LEAST 15 CM-1 APPROXIMATELY, (C) A VOLUMETRIC DENSITY OF 0.4 G / CM3 APPROXIMATELY 1.4 G / CM3 APPROXIMATELY AND (D) ENOUGH MECHANICAL STRENGTH TO MAINTAIN THE STRUCTURAL INTEGRITY OF THE STRUCTURE. CONDITIONS OF USE AND HANDLING.
