KATALYSATOR FUER DIE OXIDATION VON (METH)ACROLEIN ZU (METH)ACRYLSAEURE

Process and plant for treating exhausted DeNOx catalyst plates

Exhausted catalyst plates (4) contain, in part, valuable materials which at the same time cannot be disposed of entirely without problems. For this reason it is desirable to reprocess the exhausted catalyst plates to such an extent that the lowest possible amounts must be disposed of and the valuable raw materials can as far as possible be supplied for re-use. In this case it has proved to be difficult to detach the catalytically active substances from the support metal sheet. By immersing the plate catalysts in a solution which dissolves the layer on which the catalytically active substances are applied, it is possible to detach the catalytically active substances from the support metal sheet (50) and then to filter them off from the solution. Both the bare support metal sheets and the residue (36) filtered off from the solution can be supplied for re-use after a further treatment stage (40). The process and the plant are especially suitable for reprocessing exhausted DeNOx catalyst plates ...

A process for transforming hydrocarbon oils into other hydrocarbons having a lesser number of carbon atoms in the molecule

Hydrocarbon oils, for example crude oils, low temperature tar oils, and shale oils, are converted into aromatic hydrocarbons and gas rich in ethylene by contacting them in vapour state, substantially unmixed with free oxygen, with a mixture of at least two of the following three oxides, viz: molybdic, chromic, and ferric oxides, activated with vanadium pentoxide, at about 800-1100 DEG F. to dehydrogenate the hydrocarbons, the unsaturated aliphatic hydrocarbons in the product then being hydrogenated to yield olefins and paraffins. Preferably equal weights of the three oxides are used, but variations up to 10 per cent more or less of each are permissible. Vanadium pentoxide is equivalent to about 2-10 per cent of the weight of the other oxides. The hydrogenation is effected by passing the products with steam over a mixture of 90-98 per cent iron and 2-10 per cent copper in finely-divided form at about 1000-1400 DEG F. Suitable apparatus comprising a converter with lower and upper sets of ...

CATALYST CARRIERS, A PROCESS FOR THEIR PREPARATION, AND THEIR USE IN MAKING CATALYSTS FOR THE CONVERSION OF HYDROCARBON CHARGES

VANADIUM-FREE CATALYST FOR SELECTIVE CATALYTIC REDUCTION AND METHOD OF PRODUCTION THEREOF

Selective catalytic reduction with ammonia or a compound which can be decomposed to give ammonia is a known process for removing nitrogen oxides from the exhaust gas of predominantly lean-burn internal combustion engines. Most of the vanadium-containing SCR catalysts used for this purpose to date are notable for a good conversion profile. However, the volatility of vanadium oxide at relatively high exhaust gas temperatures can lead to the emission of toxic vanadium compounds. Zeolite-based SCR catalysts, which are used especially in batchwise SCR systems, are a very costly solution to the problem. A process is presented, with which a homogeneous cerium-zirconium mixed oxide is activated for the SCR reaction by introducing sulfur and/or transition metal in a defined manner. The use of this process provides a highly active, ageing-stable SCR catalyst which constitutes a vanadium-free, inexpensive and high-performance alternative to the SCR catalysts to date and is suitable especially for ...
