A method for the production of nanocrystalline hydrotalcite compounds

摘要

The present invention relates to a process for the production of nanocrystalline hydrotalcite compounds, comprising the steps of: introduction of one or more starting compound (s) into a reaction chamber by means of a carrier fluid, subjecting the starting compound in a treatment zone acting in a pulsating manner under a thermal treatment at a temperature of 250°C. to 450°C, form of nanocrystalline metal oxide particles, dispensing of the resulting nanocrystalline hydrotalcite particles from the reactor, wherein the starting compound (s) in the form of a solution, suspension, suspension or in a fixed aggrgatzustand is introduced into the reaction chamber, as well as a nanocrystalline hydrotalcidmaterial, obtainable by the method according to the invention and their use as adsorbtions - and material.
