How to turn coal tar pitch into activated carbon?
Thread Content
I would like to ask the experts: can the asphalt, a by-product of direct coal-to-oil conversion, be used to produce activated carbon? If it is feasible, what technologies and equipment should be used?
The Shanxi Coal Chemistry Institute seems to have relevant technologies for pitch-based activated carbon
Spherical activated carbon, especially the medical-grade spherical activated carbon used for blood purification, is one of the most cutting-edge areas in the research of carbon materials. Due to the complex multi-disciplinary techniques involved in its production and application, only Japan has been able to produce it commercially to date. With the support of **863 projects, key projects of the Chinese Academy of Sciences, and major projects funded by provincial and ministerial departments, key issues such as cost control for oxidation stabilization and performance control for regulating the pore size of activated carbon were resolved. Asphalt-based spherical activated carbon suitable for blood purification was developed, earning the second prize for scientific and technological progress in Shanxi Province. To simplify the manufacturing process and develop new products, based on systematic studies of the balling process conditions and the structural properties of the resulting activated carbon, resin-based spherical activated carbon in the millimeter range that can also be used for blood purification, as well as resin-based spherical activated carbon in the micron range for use as electrode materials, have been successfully developed.
Thank you, the person above. I also know a bit about the relevant technologies of the Shanxi Coal Chemistry Institute. Are you from the Coal Chemistry Institute?
