The present invention relates to a solids dosing device for finely divided solids, comprising sampling means for withdrawing a sample from a sampling jar and dosing means for inserting a prescribed amount of finely divided solid material into a testing jar, a dosing accuracy of at least 0.1 g being achieved with the solids dosing device and characteristics of the dosed amount substantially corresponding to those of the sample in the sampling jar. The invention also relates to an automated analyzer for determining properties of finely divided solids, comprising a depot for sampling jars and testing jars, analysis devices for the analysis of samples, manipulators for the movement and positioning of sampling jars, solids dosing devices and dosing devices for liquids. Furthermore, the invention relates to a method for the automatic analysis of finely divided solids.

Automatic analysis of finely divided solids

A method of charging a vertical tube having an internal diameter of 50 mm or less with catalyst particles, which comprises introducing a filling aid into the vertical tube, where the filling aid comprises a flexible elongated body and the ratio of the cross section of the flexible elongated body to the cross section of the tube is from 0.003 to 0.08, and introducing the catalyst particles into the tube.
