Sequential production of a library of solids (especially heterogeneous catalysts) comprises dosing solutions, emulsions and/or dispersions into a mixer and drying, with variations and repetition

摘要

Sequential production of a library of N different solids (especially heterogeneous catalysts) whereby N reaches an integer = 2 in one day involves dosing solutions, emulsions and/or dispersions into a mixer and drying the mixture, the ratios in the dosing step being varied and the dosing, drying and variation steps being repeated N-1 times. Sequential production of a library of N different solids (especially heterogeneous catalysts) whereby N reaches an integer = 2 in one day involves (a) production of (i) = 2 different sprayable solutions, emulsions and/or dispersions of elements and/or compounds providing chemical elements as solids and optionally (ii) inorganic carrier dispersions; (b) continually dosing the solutions etc. in predetermined ratios into a mixer to give homogeneous mixing; (c) continuously drying the mixture and removing it from the mixer; (d) varying the ratios in step (b) and repeating the steps (b), (c) and (d) N-1 times to recover N different dry mixtures; and (e) optionally forming and optionally calcining the mixtures to yield solids. Independent claims are also included for (1) an apparatus for the sequential production comprising = 2 vessels for the solutions etc., a mixer, pumps and interconnecting tubes for the vessels and the mixer, a dryer connected to the mixer, and a central computer controlling the pumps and (2) parallel testing of the solids library for desired catalytic properties by separately introducing the individual solids into multi-reactors and then testing them.
