摘要： A closure device for a bulk material system is provided, specifically for regulating a flow of heat transfer particles. The closure device includes a bulk material guide which has a first opening for connection to the bulk material system and a second opening for the discharge of a bulk material guided by the bulk material system, and a closure blade which is rotatably mounted about an axis of rotation. The closure blade, in a first rotational position, closes the second opening and, in a second rotational position, at least partially uncovers the second opening. The closure blade is mounted in such a manner to reduce jamming of the closure device in operation.

摘要： A method and a device are provided for producing activated carbon in a gasification process. A first process stage includes thermally decomposing a carbonaceous starting material, in particular biomass, in a first reaction zone to produce pyrolysis coke and pyrolysis gas. A second process stage includes generating, from the pyrolysis gas in the second reaction zone, a product gas which can be used for activating the pyrolysis coke. A third process stage includes activating at least a portion of the pyrolysis coke to form activated carbon with the aid of the product gas in the third reaction zone.
