摘要:
The invention relates to a supported catalyst consisting of a support (T) comprising at least 75 wt. % Al2O3 and rhenium compounds as the active component (A). According to the invention, the maximum distribution function of the pore diameter lies in the mesopore range between 0.008 and 0.050 µm.
摘要:
The invention relates to a method for a Re2O7 doped catalyst support deactivated (deactivated catalyst) by a hydrocarbon mixture containing C2-C6 olefin (C2-6 lot) used during a metathesis. The inventive method consists in treating the deactivated catalyst at a temperature ranging from 400 to 800 °C with an inert gas (regeneration gas K1). Afterwards, the thus pre-treated deactivated catalyst is treated with said regeneration gas K1 and an oxygen-containing gas (regeneration gas K2).
