Abstract: A process for coating internals in a reactor, except for the coating of electrically heatable, at least partly open-cell foams, with a catalytically active material or a precursor thereof, in which an aerosol which contains the catalytically active material or the precursor thereof as a disperse phase is provided and the aerosol is passed through the reactor at a rate in the range from 0.1 to 4 m/s, which is established so that the disperse phase of the aerosol is deposited on the internals in the reactor.

Abstract: The invention relates to a method for coating internal fittings in a reactor , except for electrically heatable, at least partly open-cell foams, with a catalytically active material or a precursor therefor. According to said method, aerosol containing the catalytically active material or the precurso r therefor as a dispersed phase is provided and is directed through the reacto r at a speed which is set in such a way that the dispersed phase of the aeroso l deposits on the internal fittings of the reactor.

Abstract: The invention relates to a method for the production of a salt-free aqueous hydroxylamine solution by distilling an aqueous solution of an hydroxylammonium salt and a base in a plate column having at least two mechanical plates. The invention is characterized in that packings or structured packings are placed above at least one of the plates of the plate column along the cross section of said column.

Abstract: The method involves subjecting the particles to electromagnetic radiation that is scattered on the particles, determining the intensity of the scattered radiation in at least two different scattering regions and setting them in relation to each other. One scattering region contains the forward scattering region and another the rearward scattering region. Independent claims are also included for the following: (1) an arrangement for determining collective physical parameters of particles in gases; (2) a use of the method for aerosols in gases; (3) a computer program for implementing the method; (4) a data medium with a computer program.

Abstract: The invention relates to a method for producing a highly pure, aqueous hydroxylamine solution by distilling an aqueous solution, devoid of salt, of a hydroxyl ammonium salt in a plate column comprising at least two mechanical plates. Said method is characterised in that packing bodies are arranged between at least two plates of the plate column over the cross-section of sa id column.

Abstract: The invention relates to a process for vapor deposition of one or more compounds onto a support, in which (i) the compound is introduced in a solid or gaseous state into a carrier gas stream, (ii) the compound is present in a gaseous state in the carrier gas stream, (iii) the gaseous compound is precipitated, (iv) the compound precipitated in step (iii) is once again brought into the gaseous state, and (v) the gaseous compound is subsequently precipitated on the support, wherein the carrier gas stream comprising the gaseous compound(s) is cooled to a temperature below the sublimation temperature of the compound(s) by introduction of a gas stream.
