Abstract
The invention relates to a ceramic material comprising at least one transition metal silicate and/or transition metal disilicate. The ceramic material can be characterized by having one or more monosilicates, one or more disilicates and mixtures consisting of monosilicates and disilicates.
Claims7
A method of precipitating SiO2-rich slags from a flue gas stream which comprises contacting the gas stream with a ceramic comprised of at least one transition metal silicate and/or transition metal disilicate with a mixing gap between the transition metal silicate and/or the transition metal disilicate and the SiO2 of the slag, the precipitation of SiO2 rich slag being effected from the hot flue gas of a coal-fired gas and steam power plant.
A method of precipitating SiO2-rich slags from a flue gas stream which comprises contacting the gas stream with a ceramic comprised of at least one transition metal silicate and/or transition metal disilicate with a mixing gap between the transition metal silicate and/or the transition metal disilicate and the SiO2 of the slag, the precipitation of SiO2-rich slag being effected from the hot flue gas of a coal, wood, biomass or clarifier sludge gasifier.
A method of precipitating SiO2-rich slags from a flue gas stream which comprises contacting the gas stream with a ceramic comprised of at least one transition metal silicate and/or transition metal disilicate mixing gap between the transition metal silicate and/or the transition metal disilicate and the SiO2 of the slag, the precipitation of SiO2-rich slag being effected from the flue gas of a disposal plant for filter ash from garbage incinerators.
