Technique for producing fuel by using deposed organic substance

Abstract

This invention relates to a technique for producing fuel oil from waste organic matters, such as plastics, rubbers, fibers, residual oils, waste oils, plant oils and animal oils. The technique comprises: dissolving the raw materials, removing impurities, pyrolyzing, catalyzing, mixing, rectifying, decolorizing and synthesizing. The obtained fuel oil is transparent, clear and fragrant.

Description

Technical field: [0001] The invention belongs to the field of oil chemical industry, and in particular relates to a process for producing fuel oil from waste organic matter (plastic, rubber, fiber, residual oil, waste oil, vegetable oil, animal oil, etc.). Background technique: [0002] There are many existing oil-to-chemical technologies, each of which is different. Among them, the more advanced ones, such as the CN1164542A patent disclosed by Nanjing University of Science and Technology, are characterized in that the cracking process is carried out under nitrogen conditions, and the hydrochloric acid produced is absorbed through the absorption tower, and the reaction products enter the catalytic bed. Cracking under the action of catalyst. The cracking reactor used is a two-stage type, and is equipped with a preparatory tank for regular decoking, and the heat energy is heated by flue gas. Although this technology can produce fuel oil, there are still the following problems:...

AI Technical Summary

Problems solved by technology

[0003] 1. A set of hydrogen chloride absorption tower is added, which is costly and laborious, and there is still a hidden danger of chlorine gas leakage

[0004] 2. The pyrotechnics of the heating furnace are thermal energy, which not only requires a tall chimney or attracting power, but also has fire hazards

[0005] 3. The two-stage reaction kettle used needs to add a preparatory kettle for decoking, which not only costs money, but also causes carbon and coking in the oil to increase the carbon particles and odor

[0008] 1. The heating device adopts the open flame flue gas radiation cracking of the coal furnace, and the skin of the kettle and the steel plate are easy to oxidize and leak and crack, causing a catastrophe

[0009] 2. The reaction medium produces a large amount of coke, which not only cannot be removed, but also affects the quality of the oil and increases the odor

[0010] 3. The fuel oil produced is unqualified because there is no post-processing reaction

[0011] 4. Although the cracker adopts a double-layer structure and the outer layer is made of cast iron, it can prolong the service time, but because there is an air barrier between the double layers, the heat loss is large, fuel consumption is high, and the cracking time is prolonged
