APPARATUS FOR CONTACTING SOLIDS IN THE FORM OF FLOWABLE LUMPS WITH LIQUIDS AND, OPTIONALLY, GASES

摘要

The instant invention relates to an apparatus for contacting solids in the form of flowable lumps with liquids and, optionally, gases, particularly for producing aluminium alcoholates by reacting aluminium with an excess of an aliphatic C3 to C10 alcohol, wherein solids charged to a reactor from the top are contacted in a spouted bed with liquid or a mixture of liquids and a rotary grate is provided for holding at least temporarily the aluminium lumps in the form of ingot off cuts.
