Embodiment

[0029] 1. Preparation of the enzyme composition of the present invention

[0030] Take 5ml of laccase isoenzyme (CAS NO.80498-15-3) with a concentration of 1ppm and 50g of ammonium acetate, add it to 50L of clean water and evenly stir, and store at 4°C-15°C before use.

[0031] 2. Treatment of coal with the enzyme composition of the present invention

[0032] First, the coal is ground into pulverized coal, 80% of which can pass through a 200-mesh sieve, and the pulverized coal is roasted so that its moisture content is less than 17%. The enzyme composition prepared in Example 1 was evenly sprayed on the dried pulverized coal, and the pulverized coal was evenly stirred at 9, 12, and 17 o'clock, respectively. The sprayed pulverized coal was allowed to stand for 72 hours under the condition of avoiding sunlight, and the combustion experiment was carried out after standing for 72 hours. The control group was sprayed with water.

Abstract

The invention provides a fermentation technology of an enzyme composite (3Ec nano enzyme) and a method for treating coal by using the enzyme composite. The enzyme composite comprises laccase isozyme, coenzyme and ammonium acetate, wherein the enzyme is selected form one or more enzymes of the laccase isozyme, pyruvate dehydrogenase, dihydrolipoyl acetyltransferase, dihydrolipoyl dehydrogenase, the coenzyme is selected form one or more enzymes of coenzyme A, coenzymeA-SH, lipoic acid, thiamine pyrophosphate, flavin adenine dinucleotide and nicotinamide adenine dinucleotide. The invention also provides a coal treatment method which comprises the steps of spraying the enzyme composite on coal and standing for more than 72 hours; and the coal treatment method can effectively improve the coal combustion efficiency, lower the generation of oxides of carbon, nitrogen and sulphur and coal ash, and reduce the hot corrosion to devices during the combustion of coal.

Description

technical field [0001] The present invention relates to a fermentation technology of an enzyme composition, and particularly relates to an enzyme composition that can promote coal combustion efficiency and reduce the production of nitrogen and sulfur compounds. Background technique [0002] Coal is a fossil fuel whose main components include carbon, hydrogen, oxygen and small amounts of nitrogen, sulfur or other elements. Sulfur is one of the most important impurities in coal, and it usually occurs in coal combustion products in the form of sulfides. In some countries, such as the United States, regulations have been established to control sulfide emissions, and because the cost of removing such harmful impurities is expensive, governments are rewarding the production of low-sulfur coal to reduce pollution. [0003] According to the degree of carbonization, coal can be divided into peat, lignite (brown lignite, black He coal), bituminous coal (bituminous coal) and anthracit...
