FIELD : chemistry.
SUBSTANCE : present invention relates to a combustion catalyst for combustion and removal of carbon-bearing material, to a method of preparing said catalyst, to a catalyst support and preparation method thereof. The method of preparing the carbon-bearing material combustion catalyst involves steps for mixing, drying and burning. At the mixing step, zeolite, except sodalite, and an alkali metal source and/or alkali-earth metal source are mixed in a polar solvent such as water or another in a defined ratio. At the drying step after mixing, the liquid mixture is heated with evaporation of water in order to obtain a solid substance. At the burning step, the substance is burnt at temperature of 600°C or higher to obtain a carbon-bearing material combustion catalyst. The invention describes a method of preparing a support for the carbon-bearing material combustion catalyst on a ceramic substrate, whereby the catalyst support is designed for combustion of carbon-bearing material contained in exhaust gas of an internal combustion engine, involving attaching the combustion catalyst made using the described method onto a ceramic substrate and a catalyst support made using this method.
EFFECT : stable combustion and removal of carbon-bearing material at low temperature for a long period of time.
