Abstract: 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.

Abstract: An apparatus for manufacturing book covers having a board feed for supplying cover boards and a spine insert having a covering material feed for supplying covering material, having a covering material cylinder, by means of which the supplied covering material is taken over, conveyed past a glue spreading roller and assembled with the supplied cover boards and having a folding and pressing apparatus as well as having a delivery apparatus and having a drive apparatus for the covering material feed, the board feed the covering material cylinder and the folding and pressing apparatus it is provided that at least the covering material feed the board feed and the folding and pressing apparatus are drivable in each case independently of one another. The covering material cylinder is preferably also provided with an independent drive.
