A method and an apparatus for continuously preparing a ketose solution from a starting sugar solution including at least one aldose, wherein at least one vertical continuous multicontact reactor (1) is used, at least one tectosilicate or a clay capable of forming a heterogeneous isomerisation catalyst is continuously circulated through the reactor (1), and at least one microporous selective adsorption solid, selected so that it selectively absorbs the aldoses in the starting solution or the ketoses produced by isomerisation, and is compatible with the isomerisation conditions, is circulated downwards through said reactor (1).
