摘要:
The invention relates to a synthesis reactor and to a method for producing vinyl acetate, in which gaseous ethylene and acetic acid, in addition to oxygen or gases containing oxygen, react catalytically. The inventive synthesis reactor is a wall reactor, in which the catalytic synthesis takes place in a plurality of reaction chambers, whose free flow cross sections measure less than 2000 μm, preferably 1000 μm and whose indirectly cooled walls are coated with a palladium-gold catalyst.
摘要:
A process for reactions with or to form peroxidic compounds in a wall reactor whose reaction space has a specific material coating is described.Both higher space-time yields and increased selectivities can be achieved by means of the process.
摘要:
Catalyst-coated support, method for producing the same, reactor comprising the same and use thereof. Supports having a catalytic coating comprising at least one porous and cavity-containing catalyst layer are described, cavities being irregular spaces having dimensions greater than 5 μm in at least two dimensions or having cross-sectional areas of at least 10 μm2. The catalytic coatings are distinguished by a high adhesive strength and can preferably be used in microreactors.
