Semi Coke /Gas Coke /Lam Coke

Semi-coke is a low-volatility solid phase combustible with a developed pore structure formed after pyrolysis of coal. It is mainly a solid product obtained by low-temperature (500-700°C) dry distillation of peat, lignite and high-volatile bituminous coal. Semi-coke has a black and porous appearance, and its main components are carbon, ash and volatile matter.

Since non-caking coal does not soften and melt during carbonization and only removes part of the volatile matter, the solid product obtained by low-temperature carbonization of non-caking coal is sometimes called carbonized carbon to distinguish it from the solid product obtained by low-temperature carbonization of caking coal.

• High calorific value, low ash, low sulfur and phosphorus: Semi-coke has a high fixed carbon content and low ash, sulfur and phosphorus content. This enables it to generate higher heat during the combustion process, while reducing the emission of harmful substances and meeting environmental protection requirements.
• Good reactivity: Semi-coke has good reactivity, burns easily and is smokeless. Its critical air blast volume value is low, indicating its strong reactivity. This good reactivity makes semi-coke have broad application prospects as a reducing agent and carbon source in metallurgy, chemical industry and other fields.
• Large specific surface and adsorption performance: Semi-coke has a large specific surface area, and its adsorption performance is close to activated carbon or carbon molecular sieves. This makes semi-coke potentially useful in adsorption and separation fields.
• Abundant sources and lower costs: Semi-coke is a by-product or intermediate product in the coal conversion process, so its sources are abundant. At the same time, due to the relatively low production cost of semi-coke, its price in the market is competitive.
• Wide range of applications: Semi-coke has a wide range of applications in various industries. In thermal power plants, cement plants and other industries, semi-coke can be used as fuel; in refractory manufacturing, metallurgy, aluminum industry and other industries, semi-coke can be used as reducing agent and carbon source.
