Embodiment 1

[0032] 1 part of aluminum acetylacetonate, 1 part of ferrocene, 1 part of sodium naphthenate, 3 parts of N,N-dimethylformamide, 1 part of dimethyl sulfoxide, 1 part of dodecylsulfonic acid, stearin 1 part of triglyceride, 1 part of diphenyl phthalate, 1 part of simethicone, 200 parts of diesel oil, and 50 parts of heavy oil. Add aluminum acetylacetonate, ferrocene, sodium naphthenate, dodecylsulfonic acid, glyceryl stearate, diphenyl phthalate and dimethyl silicone oil to N, N-dimethyl In the formamide and dimethyl sulfoxide solution, stir rapidly to obtain an emulsion, and add diesel oil while stirring rapidly. After adding diesel oil, add heavy diesel oil, stir thoroughly to obtain a semi-clear solution, with a small amount of insoluble matter, filter, and the clear liquid is the coke additive.

Abstract

The present invention relates to coal additive and method for raising coke output and performance. The coal additive contains surface activating catalyst, co-solvent, permeation assistant and solvent. When the coal additive is used, the surface activating catalyst is dissolved in the solvent, added into coal through a specific mode, and distributed on the surface of coal and inside coal under the action of the permeation assistant. During producing coke, the coal additive is heated and the volatile component is separated out, to raise the output and performance of the produced coke. The high performance coke may be used in coal burning, dry distilling, gasifying, liquefying and other fields. The present invention can reach the aims of raising the utilization rate of coal, saving coal resource, reducing pollutant, etc.

Description

technical field [0001] The invention belongs to the technical field of new energy saving, and relates to a coal additive and a method for improving coke output and performance. Background technique [0002] Energy is the material basis of national economic construction. my country's primary energy is mainly coal, and the proportion of coal in primary energy demand is about 70%. According to statistics, in the total amount of coal consumed in my country, the coal directly used for thermal power generation, industrial boilers, industrial kilns and household stoves is as high as 85%. However, due to the traditional way of using coal and low-level combustion efficiency, the contradiction between energy supply and demand in my country is sharp, energy utilization efficiency is low, energy technology is backward, and the unit energy consumption of major industrial products is 20-50% higher than that of advanced countries. At the same time, due to the direct combustion of a large...
