Introduction of Ji’an Longjing Carbon Technology Co., Ltd.

colleg 11 f1This company, founded in 2010, is a professional activated carbon manufacturer integrating scientific research, development, production, and sales. The products are chemical activated carbon, physically activated carbon, and high adsorption capacity activated carbon of Longjing Carbon, which have many applications, including but not limited to decolorization of sugar liquor, decolorization of edible fats and oils, decolorization of food and beverage, decolorization and purification of gourmet powder, refining of pharmaceuticals and pharmaceutical intermediates, decolorization and decontamination of chemical raw materials, air purification, water purification, solvent recovery and refining, and environmental protection.

The company has a strong technical force and an advanced international level of energy self-sufficient activated carbon clean production technology and equipment. Additionally, it is the only company worldwide to date that biomass gasification for simultaneous heating and chemical activated carbon. Biomass (rice husk) pyrolysis gasification for simultaneous rice husk carbon and combustible gas, of which combustible gas can be used as fuel instead of the traditional activated carbon production using coal as fuel. As a result, it not only addresses the issues of pollution and high sewage discharge from coal combustion in activated carbon enterprises but also tackles the problems of decreased quality for activated carbon due to the introduction of coal ash and the unstable activation temperatures. Gasification provides energy and equally produces hot water (80-90 °C) for the recovery of H3PO4 and washing activated carbon. Of note is that the resultant rice husk carbon can be used as thermal insulation materials in the iron-steel metallurgy industry. Besides, this technology also utilizes biomass extracts obtained from biomass gasification and wastewater (which contains phosphate, K, Na, Ca, Ma, Fe, and other organic fertilizer substances) after treating activated carbon to produce biomass-activated organic liquid fertilizers. In summary, this technology can achieve energy self-sufficient activated carbon clean production and energy-saving emission reduction.

This company owns fixed assets of over 50 million yuan and covers an area of 20000 m2. This company possesses above 80 employees, including ten middle and high technical personnel. That is, this company has many professors, doctors, masters, and undergraduate graduates in the activated carbon industry. As such, this company endows excellent research and development capabilities and can produce or modify various activated carbons according to requirements for customers.

Currently, this company has built two sets of domestic leading activation furnaces and post-treatment equipment suitable for different processes, producing 5000 t each of activated carbon and rice husk carbon each year, respectively. Notably, high-quality fir sawdust and bamboo sawdust are used as the starting material for production. Based on advanced production equipment, advanced technology, professional testing standard, and excellent management concept, this company strictly implements international, domestic, industrial, and enterprise norms and quality standards and is a model activated carbon manufacturer with advanced equipment, leading technology, stable quality, and excellent service in the activated carbon industry of china.
