Abstract:
1. A process for the sequential production of a library of N different solids, comprising heterogeneous catalysts, wherein N, within a day of beginning production, is an integer of at least 2, the process comprising a) producing at least two different sprayable solutions, emulsions and/or dispersions of elements and/or element compounds of the chemical elements present in the catalysts, b) continuously metering the at least two different solutions, emulsions and/or dispersions in a predefined ratio into a mixing apparatus in which the solutions, emulsions and/or dispersions are homogeneously mixed to form a mixture, c) continuously drying the mixture removed from the mixing apparatus, wherein the drying is performed by spray drying or spray-freeze drying, to produce a dried mixture, and recovering the dried mixture that is a solid, and d) changing the ratios in b) and repeating b), c) and d) (N−1) times until N different solids are obtained; wherein the ratio in b) and d) is set and changed by changing or adapting the flow velocities of the different solutions, emulsions and/or dispersions during the metering into the mixing apparatus and the total stream of the individual solutions, emulsions and/or dispersions remains constant during the metering in the mixing apparatus and to the drying.
