Shenmulan charcoal is a geographical indication certification trademark.

Shaanxi Shenmu is the coal accumulation center of the Shenfu Jurassic coalfield. The county's coal storage area is more than 4,500 square kilometers, accounting for 60% of the total area, with proven reserves of more than 50 billion tons. The coal seam has simple geological structure, stable storage, shallow burial, easy mining, and excellent coal quality. It is a high-quality thermal and environmentally friendly coal with extra low ash, extra low phosphorus, extra low sulfur, high calorific value, high volatile content, weak stickiness or non-stick long flame. Coal has good chemical activity and thermal stability, and is an ideal coal for power, gasification, liquefaction, chemical industry, building materials, and civil use. The main indicators are: ash content 4-10, sulfur content 0.3-0.8, phosphorus content 0.002-0.3, moisture 5-11, volatile content 30-38, calorific value 6000 (low)-7200 kcal/kg. It is a good coal for gasification, chemical industry and power. It can be used to make activated carbon, coal-water slurry, etc. It is widely used in chemical industry and metallurgy. It is ideal for high energy-consuming industries (carbide, silicon carbide, ferroalloy and other products). raw material. It is also an ideal raw material for blast furnace injection in the steelmaking industry. Shenmu coal has low sulfur content and is the preferred coal type to reduce air pollution. Now, in order to reduce the pollution caused by coal-consuming units to the city, the governments of Beijing, Shanghai, Tianjin and other cities strongly encourage coal-consuming units to use Shaanxi Shenmu coal. Shenmu coal is favored by Vietnam. It is favored by more and more enterprises and institutions, and more cities across the country are also promoting it.

Blue charcoal is made from high-quality Jura coal blocks abundant in the Shenfu coalfield. As a new type of carbon material, it has high fixed carbon, high specific resistance, high chemical activity, and high content. With the characteristics of low ash, low aluminum, low sulfur and low phosphorus, it gradually replaces metallurgical coke and is widely used in calcium carbide, ferroalloys and ferrosilicon. The production of silicon carbide and other products has become an irreplaceable carbon material. Blue charcoal can replace coke (metallurgical coke) and is widely used in chemical industry, smelting, gas production and other industries.

Blue charcoal, also known as semi-coke and coke powder, is made from the high-quality Jura clean coal abundant in the Shenfu Coalfield. It is a new type of

carbon material. , with its characteristics of high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, low sulfur and low phosphorus, it gradually replaces metallurgical coke and is widely used in calcium carbide, ferroalloy, ferrosilicon, silicon carbide, etc. The production of products has become an irreplaceable carbon material.

Blue charcoal (also known as semi-coke and coke) has a massive structure, a particle size of generally above 3mm, and a light black color. At present, there are two main specifications of blue charcoal: one is soil-refined blue charcoal The second is machine-made blue charcoal; although the two specifications of blue charcoal are made from the same high-quality clean coal, their costs and quality are also very different due to different production processes and equipment.
