REHENIUM-CONTAINED TRACTION CATALYSATOR AND PROCEDURES FOR HYDRYING CARBON PRODUCTIONS IN A FLIGHT PHASE BEFORE USE OF THE CATALYSATOR

摘要

A supported rhenium containing catalyst (I) contains a further metal from Group 8 or 1b, preferably ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os,) iridium (Ir), platinum (Pt), copper (Cu), silver (Ag) or cobalt (Co) in the form of at least one bimetallic precursor compound applied to the support. An Independent claim is also included for a process for the production of mixtures of tetrahydrofuran and gamma-butyrolactone by catalytic hydrogenation of carbonyl compounds using the catalyst (I).
