Abstract:
The invention relates to a reactor (R) for performing a three-phase reaction of a fluid phase (1) and a gaseous phase (2) on a packed bed catalyst (F), the packed bed catalyst (F) being disposed horizontally in the reactor (R) and the fluid phase (1) and the gaseous phase (2) being fed through the reactor (R) from the bottom to the top, using a mixing and distributing device (MV) across the packed bed catalyst (F), characterized in that the mixing and distributing device (MV) comprises a trough distributor (TV) for the fluid phase (1) having trough-shaped channels (K) and drain tubes (A) in the trough-shaped channels (K) for the fluid phase (1), and a distributor floor (B) disposed below and at a distance from the trough distributor (TV) in which vertical spouts (T) are disposed, having one or more openings (P1) for the inlet of the gaseous phase (2) and one or more openings (P2) disposed below the openings (P1) for the inlet of the gaseous phase, for the inlet of the fluid phase (1) into the spouts (T), and the number and size of the openings (P2) for the inlet of the fluid phase (1) being designed such that the fluid level on the distribution floor (B) is adjusted to be below the openings (P1) for the inlet of the gaseous phase (2) and above the openings (P2) for the inlet of the fluid phase (1) for a prescribed inlet flow of fluid.
Abstract:
The present invention relates to a process for isomerizing linear alpha-olefins having from 4 to 8 carbon atoms over a heterogeneous catalyst, wherein the catalyst comprises a hydrogenation metal and a selectivity promoter selected from among selenium and tellurium on a support, and also a process for preparing 1-olefins by a metathesis reaction of 2-olefins with ethene, wherein the 2-olefins are prepared by the above mentioned isomerization process.
