    摘要： Process for producing a supported catalyst which comprises at least 75% by weight of Al2O3, whose proportion of Al2O3 in the delta or theta modification is, based on the proportion of Al2O3, at least 1% and which comprises a rhenium compound and, if appropriate, a promoter as active component (A), which comprises a) converting a customary support (S) which comprises at least 75% by weight of Al2O3 and to which a promoter may, if appropriate, have been applied is converted into a modified support (S) whose proportion of Al2O3 in the delta or theta modification is, based on the proportion of Al2O3, at least 1% by calcining the customary support (S) at a temperature of from 750 to 1100°C., b) producing a supported catalyst precursor from the modified support (S) by applying the active component (A) comprising the rhenium compound to the modified support (S) and c) calcining the supported catalyst precursor at a temperature of from 500 to 750° C.

    摘要： Process for preparing a stream consisting essentially of ethene (stream C2=), a stream consisting essentially of propene (stream C3=), a stream consisting essentially of isobutene and possibly other olefins having 4 carbon atoms (stream C4=) and a stream consisting essentially of 2-methyl-2-butene and possibly 2-butene (stream C5=), and, if appropriate, a stream which comprises other hydrocarbons (stream Cx) and may consist of a plurality of separate substreams, which comprises a metathesis step in which a C4-hydrocarbon stream comprising at least 15% by weight of 2-butenes, at least 5% by weight of isobutene and not more than 5% by weight of 1-butene (feed stream) is brought into contact with ethene in the presence of a customary metathesis catalyst and the resulting hydrocarbon stream is fractionated to give the streams C2=, C3=, C4= and, if appropriate, Cx and all or part of the stream C5= is recirculated to the metathesis step.
