  • Patent number: 5347068
    Abstract: Method for simultaneous disposal of solid and liquid wastes including the steps of gasifying in a fixed bed pressure gasifier a gasification material containing coal and 1 to 70% of a solid waste material containing sulfur, hydrocarbons, PCBs, dioxins and/or heavy metals, to form a pollutant and dust-containing fixed bed pressure gasification crude gas; post-gasifying in a post-gasifier at a temperature greater than 1,000.degree. C. and with a dwell time of more than 2 seconds the crude gas together with an oxygen-containing gas and a liquid waste portion having a heat content of greater than 20,000 kJ/kg and containing hydrocarbons, PCBs and/or heavy metals to form a disposal gas; cooling the disposal gas to less than 200.degree. C.

  • Patent number: 5232487
    Abstract: A method of simultaneous disposal of liquid and solid wastes comprises the steps of introducing liquid and solid wastes into a gasification reactor with a cooled reactor inner wall and liquid slag discharge and gasifying the liquid and solid wastes at a temperature which is at least 50.degree. C. higher than a melting temperature of mineral components of the solid wastes with a dwelling time of a produced gas in the gasification reactor more than 2 seconds.
