Abstract
A hydroformylation process can be used for short-chain olefins, especially C2 to C5 olefins, wherein the catalyst system is heterogenized on a support that contains a porous ceramic material. Systems can also be used for carrying out said process.
Claims13
A process for hydroformylating C2 to C8 olefins in a reaction zone using a heterogenized catalyst system, the process comprising:
- passing a gaseous feed mixture containing the C2 to C8 olefins together with synthesis gas over a support composed of a porous ceramic material, on which the catalyst system is in a heterogenized form;
- wherein the catalyst system comprises a metal from group 8 or 9 of the Periodic Table of the Elements, at least one organic phosphorus-containing ligand, a stabilizer, and optionally, an ionic liquid;
- wherein the support is in the form of a powder, in the form of a granular material, or in the form of pellets and wherein the support consists of a carbidic ceramic material, a nitridic ceramic material, a silicidic ceramic material, or a mixture thereof;
- and
- wherein a washcoat of the same or another ceramic material, with respect to the ceramic material of the support, is applied on the support.
