Method for reducing oil content of oil-containing sludge pyrolyzed product

The invention discloses a method for reducing the oil content of a oil-containing sludge pyrolyzed product. The method comprises the following steps: feeding oil-containing sludge having the oil content of less than 40 percent and water content of less than 70 percent into a high-temperature furnace; distributing the oil-containing sludge to be 0-80mm thick in the high-temperature furnace; and controlling the pyrolyzing temperature in the high-temperature furnace to be 400-900 DEG C, pyrolyzing for 1-10 hours in an oxygen-free environment to obtain a pyrolyzed product having the oil content reduced to 2 percent or less. According to the method for reducing the oil content of an oil-containing sludge pyrolyzed product, the oil-containing sludge is subjected to oxygen-free pyrolyzing in thehigh-temperature furnace, which is environment-friendly, and the oil content of the oil-containing sludge pyrolyzed product can be well reduced. 本发明公开了种降低含油污泥热解产物含油率的方法，包括以下步骤：将含油率小于40％、含水率小于70％的含油污泥送入高温炉中；所述含油污泥在所述高温炉中的布料厚度为
