    摘要: A method for producing alkali carbonate crystals, including adding to an alkali carbonate and alkali hydroxide solution stream a 10 to 75 weight-% alkali hydroxide solution, charging the resulting mixture into a CO.sub.2 -containing gas whose temperature is from 150.degree. to 700.degree.C, collecting mixture remaining as liquid from the gas at the end of a residence time of mixture in gas of 0.1 to 10 seconds, separating alkali carbonate crystals from the collected mixture, and feeding the collected mixture, following the separating, back in the alkali carbonate and alkali hydroxide solution stream for another adding of alkali hydroxide solution.

    摘要: A catalyzer for detoxifying exhaust gases from an internal combustion engine wherein a monolithic catalyst body is supported within a housing having a composite damping arrangement placed in the housing between the catalyst body and the housing walls and having a portion extending axially of the catalyst body for damping radial forces acting on the body, and end portions for damping axial forces acting on the catalyst body, means cooperating with the damping means for elastically suspending the catalyst body in the housing and protecting rings positioned between the elastic holder and the catalyst body to further protect the edges of the catalyst body against destructive forces thereon.
