Abstract: A PROCESS FOR COATING INTERNALS IN A REACTOR, EXCEPTOR FOR THE COATING OF ELECTRICALLY HEATABLE, AT LEAST PARTLY OPEN-CELL FOAMS,WITH A CATALYTICALLY ACTIVE MATERIAL OR A PRECURSOR THEREOF IS DESCRIBED, IN WHICH AN AEROSOL WHICH CONTAINS, AS A DISPERSE PHASE, THE CATALYTICALLY ACTIVE MATERIAL OR THE PRECURSOR THEREOF IS PROVIDED AND THE AEROSOL IS PASSED THROUGH THE REACTOR AT A VELOCITY WHICH IS ESTABLISHED SO THAT THE DISPERSE PHASE OF THE AEROSOL IS DEPOSITED ON THE INTERNALS IN THE REACTOR.

Abstract: Gas coolers in which hot gasses are brought into contact with a moving cooling liquid film are used for cooling hot gasses and thus for preventing the formation of condensation cores. In a process for cooling hot gaseous reaction products from gas phase reactions for preparing glyoxal of compounds of general formula (I): H2C=C(R )-C(R )=O, in which R is hydrogen or methyl and R is hydrogen or OH, in particular acrolein, methacrolein, acrylic acid and methacrylic acid, hot gaseous reaction products are brought into contact with a cooling liquid in a gas cooler, and the cooling liquid is present in the form of a moving liquid film.

Abstract: Procedimiento para la reducción de la descarga ocasionada por aerosol de una columna de separación (1), en la que, a partir de una mezcla de partida gaseosa o líquida (G), se separa uno o varios componentes en incorporaciones eficaces en la separación (2), estando presentes o formándose aerosoles en la fase gaseosa en la columna separadora (1), segmentándose las incorporaciones eficaces en la separación (2) en uno o varios puntos de separación, y previéndose en cada punto de separación una incorporación (3), caracterizado porque el punto de separación, o los diversos puntos de separación, se determinan de tal manera que los aerosoles presentan al menos un 50 % de su tamaño de partícula máximo en el punto o los puntos de separación, entendiéndose por tamaño de partícula el diámetro medio referido a la masa de distribución de partículas, y porque la incorporación (3) se acciona en régimen inundado al menos parcialmente, forzándose, al menos en zonas parciales de la incorporación (3), una faselíquida continua, a la que se unen los aerosoles.

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.
