摘要： 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.

摘要： 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 said column.

摘要： Gas streams containing soluble-salt forming gaseous pollutant and aerosol pollutant are treated by passing the gas at a specified velocity and temperature, and if necessary after saturating the gas with vapor, through a scrubbing column where it is washed with liquid, at a temperature of at least 2 degrees C lower than the gas temperature, to produce a vapor phase which is more than 100% saturated. Gas streams containing at least one soluble-salt forming gaseous pollutant and at least one aerosol pollutant, of particle size 0.01-10 micron, are treated to remove these by passing the gas at a velocity of at least 0.5m/s, at a temperature of 30-100 degrees C, and if necessary after saturating the gas with vapor, through a scrubbing column providing a contact area of 50-1000m /m packing, where it is washed with liquid, at a temperature at least 2 degrees C lower than the gas temperature, to produce a vapor phase which is more than 100% saturated. The scrubbing liquid may be water, acid, alkali or organic solvent.

摘要： 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 precursor therefor as a dispersed phase is provided and is directed through the reactor at a speed which is set in such a way that the dispersed phase of the aerosol deposits on the internal fittings of the reactor.
