Summary of production process technology

The production technology of coal based activated carbon mainly includes raw material preparation, kneading and molding, carbonization, activation and postprocessing process, of which the most important is the process of activation, so the activation process of active carbon in the production process is the production process is the most studied. Although the industrial production of activated carbon in China started in the late 1950s, its rapid development was in the middle and late 80s. After ten years of development and perfection, to 1999, the annual output of China activated carbon has been ranked second in the world, only Yu Meiguo, the annual export volume is the highest in the world, and in the international carbon industry has important influence, while output growth also promoted the development of activated carbon Chinese production process the technology, which makes in the production technology of activated carbon and activated carbon production China world advanced level in the gap is shrinking, in the production process of activated carbon in the activation process of the most important too. At present, activated carbon production methods at home and abroad can be divided into four main categories: (1) chemical activation method, (2) physical activation method, (3) chemical physics activation method, (4) catalytic activation method.

Our company adopts the method of physical activation production, using the 336 type of SERP furnace production, its advantages are: high yield, stable product quality, product variety is easy to adjust, can also produce a variety of raw materials, high yield. The following is our company coal column, broken, powdered activated carbon production process flow chart.
