Method for comprehensively utilizing abandoned oil in coking industries

Abstract

The invention provides a method for comprehensively utilizing abandoned oil in coking industries, and belongs to the technical fields of energy chemical industries and environments. The method is characterized by being a technical scheme of an application method of a poly-generation energy chemical engineering and power system combined with the comprehensive utilization of the abandoned oil in the coking industries. According to the method, an advanced photo-catalytic oxidation technology is used for transforming abandoned oil so as to produce environment-friendly diesel oil, the product treatment is convenient, raw materials are easy to purchase, and the production cost is low. A coke oven gas byproduct obtained by coking and CO2 generated in an environment-friendly diesel oil production process are exactly subjected to hydrocarbon complementation so as to produce a synthesis gas, so that the processes of using an additional gasification furnace for supplementing a carbon source and transforming water gas so as to adjust hydrogen are avoided; and the produced synthesis gas can be directly used for the synthesis of down-stream chemical products, so that a production system is simplified, and the production energy consumption is reduced. The method has the advantages that the conversion and utilization of CO2 are realized, the utilization rate of coke oven gas resources is realized, the CO2 emission is reduced, the whole production system is highly integrated, all production links are completely matched, elements are reasonably transformed and utilized in a classification manner, and a complete environment-friendly cycle production chain is formed.

Description

technical field

[0001] The invention relates to a method for comprehensive utilization of waste oil in the coking industry, which belongs to the field of energy, chemical industry and environmental technology, and specifically relates to a method for producing green diesel oil from photocatalytic conversion of animal and vegetable oils and waste oil, which is applied to coal preparation and coking industries, and especially relates to A technical proposal for an application method of polygeneration energy chemical industry and power system combined with comprehensive utilization of waste oil in the coking industry. Background technique

[0002] Coking industry is one of the main ways of comprehensive utilization of coal. With the rapid development of the coking industry, coke oven gas has become a large-tonnage secondary energy and chemical resource. Independent coking enterprises are established for the purpose of producing coke. 48% of the coke oven gas is used for self-h...
