    Abstract: Procedimiento para la obtención de cloruro de hidrógeno libre de hidrocarburos (clorados), e hidrocarburos (clorados) libres de fosgeno, a partir de un flujo de cloruro de hidrógeno que contiene hidrocarburos (clorados) y fosgeno, en el 5 cual i) en un primer paso, se conecta en serie un primer adsorbente y un segundo adsorbente y el flujo de cloruro de hidrógeno fresco, que contiene fosgeno e hidrocarburos (clorados), primero es conducido por el primer adsorbente y posteriormente por el segundo adsorbente, hasta que el primer adsorbente ya no adsorbe prácticamente hidrocarburo (clorado), ii) en un segundo paso, el flujo de cloruro de hidrógeno fresco es conducido por el segundo adsorbente mientras el primer adsorbente se regenera, asimismo, en la regeneración se obtiene, principalmente, hidrocarburo (clorado) libre de fosgeno, iii) en un tercer paso, el flujo de cloruro de hidrógeno fresco es conducido por el segundo adsorbente y luego por el primer adsorbente regenerado, hasta que el segundo adsorbente prácticamente no adsorba más hidrocarburo (clorado), iv) en un cuarto paso, el flujo de cloruro de hidrógeno fresco es conducido por el primer adsorbente, mientras el segundo adsorbente se regenera, asimismo, en la regeneración se obtiene, principalmente, hidrocarburo (clorado) libre de fosgeno, en donde los pasos i) a iv) se pueden ejecutar una o múltiples veces sucesivas.

    Abstract: (Chloro)hydrocarbon-free hydrogen chloride and phosgene-free (chloro)hydrocarbons are recovered from a hydrogen chloride stream having (chloro)hydrocarbons and phosgene. The recovery involves connecting a first adsorber and a second adsorber in series and passing the fresh hydrogen chloride stream comprising phosgene and (chloro)hydrocarbons firstly through the first adsorber and subsequently through the second adsorber until essentially no more (chloro)hydrocarbon is adsorbed by the first adsorber, passing the fresh hydrogen chloride stream through the second adsorber while the first adsorber is regenerated, with essentially phosgene-free (chloro)hydrocarbon being obtained in the regeneration, passing the fresh hydrogen chloride stream firstly through the second adsorber and subsequently through the regenerated first adsorber until essentially no more (chloro)hydrocarbon is adsorbed by the second adsorber, and passing the fresh hydrogen chloride stream through the first adsorber while the second adsorber is regenerated, with essentially phosgene-free (chloro)hydrocarbon being obtained in the regeneration.

    Abstract: Recycling of ruthenium from an used ruthenium catalyst containing ruthenium as ruthenium oxide on a carrier material, which is hardly soluble in mineral acid, comprises treating the ruthenium oxide catalyst in a hydrogen stream, where the ruthenium oxide on the carrier is reduced to ruthenium metal; treating the carrier material containing ruthenium metal with hydrochloric acid in the presence of oxygen gas, where the metallic ruthenium, as ruthenium(III) chloride is dissolved to obtain ruthenium(III) chloride solution; and optionally treating the ruthenium(III) chloride solution.

    Abstract: The invention relates to a method of controlling a hydrogenation of a starting material in a hydrogenation reactor, in which the amount of hydrogen reacted in the hydrogenation is firstly determined, the ratio of the amount of hydrogen reacted to the amount of starting material fed in is then derived, this ratio is compared with a prescribed value and, finally, at least one process parameter is altered if the ratio of the amount of hydrogen reacted to the amount of starting material fed in deviates by a prescribed amount from the prescribed value.
