Title:
METHOD FOR CATALYTICALLY PRODUCING ORGANIC SUBSTANCES BY PARTIAL OXIDATION
Document Type and Number:
WIPO Patent Application WO2002012158
Kind Code:
A3
Abstract:
The invention relates to a method for catalytically producing organic substances by partial oxidation which is carried out in the gaseous phase in the presence of molecular oxygen at temperatures in the range of from 200 to 500 DEG C in at least one reactor that is configured as a cooled tubular reactor and that contains a catalyst. A coolant flows through the cooling pipes of the reactor and a gaseous mixed product is removed from the reactor. 40 to 100 % by weight of the total amount of the catalyst of the cooled tubular reactor are disposed on the exterior face of the cooling pipes in the form of a coating. The feedstock mixture containing the feedstock and the molecular oxygen is contacted with the catalytic layers. Preferably, at least half of the cooling pipes are designed as ribbed pipes with ribs projecting from the exterior of the pipe, and the ribs are at least partially coated with the catalyst.
