Improved method for the catalyzed hydroisomerisation of hydrocarbons

Catalyst arrangement in a reactor for hydroisomerisation of hydrocarbons, wherein at least two catalyst layers are arranged in the reactor, wherein the first catalyst layer is arranged upstream and the second catalyst layer is arranged downstream, and wherein the catalyst of the first catalyst layer is a supported precious metal catalyst for a hydrogenation of the reaction fluid and the catalyst of the second catalyst layer is a bifunctional supported precious metal catalyst, the support of which has acidic or basic properties, for the isomerisation of the reaction fluid after passing through the first catalyst layer.
