Abstract

The invention belongs to the technical field of biomass carbonization, and particularly relates to a preparation method of a biomass coal combustion adjuvant. According to the preparation method disclosed by the invention, sea mud is used as a raw material, inner part of the sea mud has rich organic matter and the sea mud has high-activity nature, and through regulation with hydrochloric acid andtreatment with an ammonia solution, magnetic granules are formed, so that combustion can be effectively promoted; then the magnetic granules are combined with copper bromide, the copper bromide is combined with magnesium at the later stage to form a magnesium-copper conjugate, and then the magnesium-copper conjugate is compounded with the magnetic granules, so that providing active oxygen necessary for combustion at the preheating stage, the combustion stage and the complete combustion stage can be facilitated, and the combustion of coal, capable of releasing combustible volatile components and carbon granules in the combustion process, can be promoted; besides, metallic compounds of copper, ferrum, manganese and the like are heated to decomposed metal ions, and formation and strengtheningof C=O keys are promoted, so that the combustion is promoted; and besides, hydrogen gas is added in the calcination course, so that the biomass coal combustion adjuvant has the function of storing hydrogen, and in the combustion course, the combustion efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of biomass carbonization, and in particular relates to a preparation method of a biomass coal combustion enhancer. Background technique [0002] With the development of the world economy, the rapid increase of population and the continuous improvement of people's living standards, the world's energy demand continues to increase, resulting in a rapid increase in oil prices, and insufficient energy supply has become a bottleneck restricting the country's economic development. Energy is one of the key factors influencing the process of sustainable development. At present, my country is facing the constraints of conventional energy resources, excessive reliance on coal resources, serious pollution and low energy utilization efficiency in the use of energy. In order to reduce the impact on the environment caused by the use of fossil energy in our country and reduce our dependence on fossil energy, it is necessar...
