Shenmu Blue Charcoal

Shenmu Blue Charcoal

Shenmu Blue Charcoal is a geographical indication certification trademark.

　　Shenmu in Shaanxi is the coal accumulation center of the Shenfu Jurassic Coalfield. The county has a coal-bearing area of over 4,500 square kilometers, accounting for 60% of its total area, with proven reserves exceeding 50 billion tons. The geological structure of the coal seams is simple, the deposits are stable, the depth is shallow, and the coal is easy to extract. The coal is of excellent quality, belonging to ultra-low ash, ultra-low phosphorus, ultra-low sulfur, high calorific value, and high volatile content weakly caking or non-caking long-flame high-quality power generation and environmentally friendly coal. The coal has good chemical activity and thermal stability, making it an ideal fuel for power generation, gasification, liquefaction, chemical production, building materials, and civil use. The main indicators are: ash content of 4–10%, sulfur content of 0.3–0.8%, phosphorus content of 0.002–0.3%, moisture content of 5–11%, volatile matter of 30–38%, and calorific value of 6,000 (low calorific value) – 7,200 kcal/kg. It is an excellent coal for gasification, chemical production, and power generation. It can be used to produce activated carbon, coal-water slurry, and is widely applied in the chemical and metallurgical industries. It is an ideal raw material for energy-intensive industries (such as calcium carbide, silicon carbide, ferroalloy, and other products), and also serves as an ideal raw material for blast furnace injection in the steelmaking industry. Shenmu coal has low sulfur content, making it the preferred choice for reducing air pollution. Governments in cities such as Beijing, Shanghai, and Tianjin strongly advocate the use of Shenmu coal from Shaanxi among coal-consuming entities to reduce urban pollution. Shenmu coal is increasingly favored by enterprises and institutions, and more cities across the country are actively promoting its use.

　　Blue charcoal is produced by burning high-quality Jurassic lump coal abundant in the Shenfu Coalfield. As a new type of carbon material, it is gradually replacing metallurgical coke due to its characteristics of high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, low sulfur, and low phosphorus. It is widely used in the production of calcium carbide, ferroalloys, ferrosilicon, and silicon carbide, becoming an irreplaceable carbon material. Blue charcoal can replace coke (metallurgical coke) and is extensively used in industries such as chemicals, smelting, and gas production.

　　Blue charcoal, also known as semi-coke or coke powder, is produced by burning high-quality Jurassic lump coal abundant in the Shenfu Coalfield. As a new type

　　of carbon material, it is gradually replacing metallurgical coke due to its characteristics of high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, low sulfur, and low phosphorus. It is widely used in the production of calcium carbide, ferroalloys, ferrosilicon, and silicon carbide, becoming an irreplaceable carbon material.

　　Blue charcoal (also referred to as semi-coke or coke) has a lump structure, with particle size generally above 3mm, and a light black color. Currently, there are two main specifications of blue charcoal: one is earthen-smelted blue charcoal, and the other is machine-made blue charcoal. Although both types are refined from the same high-quality lump coal, their costs and qualities vary significantly due to differences in production processes and equipment.
