Abstract

This invention discloses a device and its application method for processing liquid fuel by catalyzing and pyrolyzing sewage and sludge, in which, the device is composed of an N2 gas tank source, a heating oven, a temperature control instrument, a condenser, a liquid phase collection bottle, a buffer bottle, an absorption bottle, a gas bag and a raw material pyrolyzing reactor, the method includes putting a pyrolyzing reactor with oil sludge and catalysts in a heating oven, giving cooling water, turning on the supply and designing temperature controlling program to heat it to 500-600 deg.C with the temperature rising speed of 5-10deg.C/min and keeping 30-40min. the content of petrol reaches to 20%, diesel oil to 50%, the rest is heavy oil, the content of C64 component in the fuel gas reaches to 40%, mild hydrocarbon gas, liquid fuel oil and solid coke can be got from the pyrolyzed sludge.

Description

Technical field: [0001] The invention relates to a technology for producing liquid fuel, fuel gas and carbon material by pyrolysis of sewage sludge, in particular to a technology for producing liquid fuel, fuel gas and carbon material by pyrolysis of oily sludge, so as to realize the purification of sewage Recycling and harmless directional control transformation of sludge. Background technique: [0002] Refinery oily sludge and municipal sewage sludge contain harmful substances such as heavy metals and organic matter. If not handled properly, it is bound to cause lasting harm to the environment. The current treatment methods for sewage sludge include: ①Incineration method: After incineration, the volume of ash is minimized, and there is no pollution problem of heavy metal ions, but incineration will produce pollutants such as dioxins. This method is widely used in Europe, America and Japan, and 61% of sludge in Japan is treated by incineration. ② Landfill method: The cos...
