example 1

[0026]Mix soybean oil and 90% ethanol solution with a mass fraction of 10:3 into a three-necked flask equipped with a stirrer and a thermometer, then put the three-necked flask into a water bath, and raise the temperature of the water bath to 60°C. Start the agitator, stir and mix at a speed of 300r / min for 30min to obtain a mixed solution; transfer the mixed solution into a separatory funnel, let stand at a temperature of 4°C for 3h, separate and obtain the upper oil phase and the lower ethanol phase respectively, Put the ethanol phase in the lower layer into a rotary evaporator, and concentrate it by rotary evaporation at 40°C for 30 minutes to obtain a concentrated solution for later use; mix the upper oil phase and activated sludge from a sewage plant at a mass ratio of 5:1 and put it into a fermenter. Seal the mouth of the tank and ferment for 7 days at 35°C. After the fermentation is over, the fermentation product is obtained and set aside. The rice husk is weighed and pl...

Abstract

The invention relates to the technical field of coal molding, and concretely relates to a preparation method of a waterproof biomass molded coal binder. The method comprises the following steps: extracting soybean oil used as a raw material by an ethanol solution to obtain a concentrate rich in soybean phospholipids, performing mixing and sealing fermentation on the soybean oil and activated sludge to obtain a fermentation product, cooking rice husks used as a raw material to obtain a cooked product, reacting the cooked product with phenol to obtain a reaction product, and mixing and reactingthe reaction product, the fermentation product and the concentrate to obtain the waterproof biomass molded coal binder. Microorganisms in the activated sludge are used to degrade the soybean oil, parts of fibers play a role in the connection and stretching of molded coal, furfural produced by the hydrolysis of rice husks reacts with phenol to improve the bonding performance of the binder and improve the water resistance, and the activated sludge added to the molded coal binder is rich in volatile groups in order to improve the gasification reactivity of the molded coal, reduce residual carbonin ash residues and improve the conversion rate of carbon, so the waterproof biomass molded coal binder has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of coal molding, in particular to a preparation method of a waterproof biomass briquette binder. Background technique [0002] my country is rich in coal resources, but the efficiency of coal utilization is low, and the way of use is not environmentally friendly. The irrational use of coal not only wastes energy but also pollutes the environment. At the same time, coal, like petroleum and other fossil resources, is a non-renewable energy source. Therefore, improving the utilization rate and clean conversion of coal is an important direction for coal utilization. [0003] Briquette is a coal product with a certain shape and strength formed by processing one or several kinds of coal powder and a certain proportion of binder or sulfur-fixing agent under certain pressure. Briquettes can improve combustion efficiency, reduce environmental pollution, and expand the application range of high-volatility and weakly ...
