Ningxia Nisi Activated Carbon Co., Ltd. was established in 2017 by Ningxia Bethel Activated Carbon Co., Ltd. (the company's old factory, established in 2003) due to the expansion of production capacity. The company covers an area of 133,400 square meters and invests about 200 million yuan. According to the latest environmental protection requirements and continuous automated production concepts, the company has built 8 automated activated carbon production lines, which can produce 100,000 tons of desulfurization and denitrification activated carbon and 10,000 tons of other types of activated carbon products.

       The company has many professional R&D personnel and testing personnel, and has established long-term technical cooperation and exchange relationships with many technical experts, scientific research institutions and enterprises, and is committed to the research and development and production of high-performance desulfurization and denitrification activated carbon. In 2019, the company applied for the establishment of the Ningxia Hui Autonomous Region's Desulfurization and Denitrification Activated Carbon (Huinong) Technology Innovation Center and obtained the confirmation and approval of the Ningxia Autonomous Region Science and Technology Department. In addition, in the most critical link of activated carbon manufacturing-forming and granulating process and activation process, the company uses the self-developed patented furnace-type "improved Slip furnace" and the cooperatively developed patented equipment "ring die granulator". Greatly improve the performance and output of activated carbon for desulfurization and denitration. The desulfurization and denitrification activated carbon produced by the company has the characteristics of high abrasion resistance and compressive strength, good uniformity of compressive strength, low consumption during use, good desulfurization and denitration performance, and reduced performance after repeated use. It has been widely used in China. Flue gas desulfurization and denitrification treatment in many large steel companies, thermal power plants, and coking plants.

       The company has passed quality, occupational health and safety, and environmental management system certification and was successively rated as "Ningxia Hui Autonomous Region Science and Technology Small and Medium-sized Enterprise", "Ningxia Hui Autonomous Region Science and Technology Small Giant Enterprise" and "National High-tech Enterprise" in 2019-2021. The company currently has 1 invention patent, 21 utility model patents, 2 scientific and technological achievements, and 1 paper. Many of these technologies have been applied to daily production. While improving the company’s product competitiveness, it has also promoted the development of the activated carbon industry. developing.
