Coke is an important raw material in the steel industry, and its quality directly influences the smelting of iron and steel. To improve coal quality and reduce coal blending costs, we need to predict the coke quality and optimize the coal blending scheme. In this paper, we propose a modeling and optimization method based on the characteristics of the coal blending and coking process.

Methanol is an important feedstock of chemical engineering and energy source, and it is mainly produced by coal route in China. The coaltomethanol suffers from serious CO 2 emissions and carbon resource waste since water gas shift is involved in this process to increase hydrogen content of syngas for meeting methanol synthesis. A novel coaltomethanol process integrated with cokeoven gas ...

The process makes the blast furnace reliant on lumpy materials to maintain a gaspermeable stock column. The most important reducing agent is therefore the lumpy coke. Auxiliary reducing agents, such as coal or oil, are injected via the tuyeres. The tasks of coke and coal for the hot metal production and the requirements of the blast furnace on ...

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

This invention is directed to a process for converting coal into useful liquids, solids, and gases, by combined processes of coal carbonization and liquefaction in which the carbonization reaction yields hydrogen suitable for the liquefaction. The heavy liquid products from the liquefaction and the carbonization may be combined with the solid char to form a metallurgical coke.
