Desulphurization refers to the process of removing sulphur from coal burning and other fuels to reduce sulphur oxide emissions. The development of desulfurization technology is of great significance to environmental protection and air pollution control. A composite desulfurizer is a mixture of chemicals that effectively removes sulfur from fuels. This article will focus on the research and use of composite desulfurizers.
Composite desulfurizers are composed of a variety of desulfurizers that remove sulfur from fuel through different mechanistic actions. Common compound desulfurizers include iron oxide, calcium oxide, ammonia, etc. These components interact to form a highly effective desulfurizer that performs better during the desulfurization process.
The research of composite desulfurizer mainly includes the design of dosage form, the optimization of composition and the evaluation of desulfurization effect. Through experiments and simulations, researchers explored the effects of different components and ratios on the desulfurization effect.
The use of composite desulfurizers can be divided into two stages, namely pretreatment and addition during combustion.
In the pre-treatment stage, a desulfurizer is added to the fuel and reacts with the sulfide to form a less active compound. This addition process can be done during the pre-treatment of the coal to reduce the sulfur content of the fuel.
During combustion, due to changes in temperature and atmosphere conditions, the active substances in the composite desulfurizer are released and react with the sulfur oxides in the fuel. This stage of addition is carried out in the combustion equipment and effectively removes sulfur oxides from the fuel.
Composite desulfurizers have the following advantages over single desulfurizers:
A variety of components interact with each other, and the desulfurization effect is better.
Dosage form design and composition optimization can be performed for different fuels and desulphurization processes.
It has a wide range of adaptability and can be used in a variety of combustion equipment and processes.
It reduces sulfur oxide emissions and reduces pollution to the atmospheric environment.
Composite desulfurizers play an important role in desulfurization technology, and their research and application have made continuous progress. Through dosage form design, ingredient optimization and desulfurization effect evaluation, researchers continue to improve the efficacy of composite desulfurizers. The use of composite desulfurizers is divided into pretreatment and addition during combustion, which can effectively remove sulfur oxides from fuel. Compared with a single desulfurizer, the composite desulfurizer has better desulfurization effect and adaptability. Through the application of composite desulfurizers, sulfur oxide emissions in the atmosphere can be reduced and contribute to environmental protection.
