    摘要: Apparatus, and a method for using the apparatus, for detoxifying material contaminated with at least one volatile organic compound (VOC). The apparatus is provided with a dryer having a heat source to heat the VOC-contaminated material to a first temperature, hot enough to volatilize the VOC, but below the cracking temperature of the VOC. The VOC in the dryer is volatilized to form VOC gases. A kiln heats the VOC gases with excess air to a second temperature, hot enough to destroy the organics in the VOC gases. Simultaneously the kiln is used to treat a kiln processable material to form a desired product. The kiln includes means for feeding the kiln processable material to the heating chamber, means for cooling and recovering the desired product, and means for providing heat for the VOC dryer. The apparatus also includes a conduit for conducting the gases containing VOC from the dryer to the kiln.
