example 1

[0022] Weigh the eucalyptus wood chips and put them into the jet mill, and pulverize for 1 hour to obtain the eucalyptus wood chips. The eucalyptus wood chips and the sodium hydroxide solution with a mass fraction of 5% are mixed at a mass ratio of 1:10 and put into a beaker, and then the beaker is placed. Put it in an oil bath, heat up to 90°C, heat treatment for 2 hours, filter and separate to obtain a filter residue; mix the filter residue and a citric acid solution with a mass fraction of 30% in a mass ratio of 1:5 to obtain a mixed solution, and then transfer the mixed solution into In the autoclave, heat up to 200°C under the condition of a pressure of 2.0 MPa, and cook at high temperature and pressure for 10 hours; after the reaction is over, the pressure is naturally released, and then hydrogen is introduced into the autoclave until the pressure in the autoclave is reached. Reached 4.0MPa, stirred and reacted at 150 ° C for 1 h. After the reaction was completed, the pre...

Abstract

The invention relates to a preparation method for a combustible biomass coal briquette binder, and belongs to the technical field of coal briquette preparation. The preparation method comprises the following steps: taking eucalypt wood dust with high volatile contents as raw materials; firstly, carrying out alkali-heat-treatment on the eucalypt wood dust; then, mixing the eucalypt wood dust subjected to the alkali-heat-treatment with organic carboxylic acid, then, carrying out high-temperature and high-pressure reaction, and carrying out hydrogenation reaction to obtain a reactant; then, carrying out rancidification on coconut oil in the environment of high temperature, high moisture and high oxygen; mixing a rancidification product and the reactant to carry out short-term fermentation; carrying out ultraviolet sterilization to obtain the combustible biomass coal briquette binder. The briquette binder prepared by the preparation method has the advantages of good binding effect, high combustion efficiency and wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a combustion-supporting biomass briquette binder, and belongs to the technical field of briquette preparation. Background technique [0002] Biomass briquette is a new technology developed in recent years. It can reduce the greenhouse gas CO through the dual functions of saving coal and replacing coal with biomass. 2 and coal-fired SO 2 The emission of briquette is conducive to alleviating climate warming and acid rain pollution, and is of great significance to protecting the environment and saving energy. It is an important direction for the development of briquette technology. Moreover, my country is rich in biomass energy. The annual biomass straw produced by agriculture can reach 700 million tons. Most of these biomass are simply burned, causing serious environmental pollution. Biomass briquette technology is a new way to develop and utilize coal and biomass energy. It makes full use of the advanta...
