Latest Patents

Enqiang Yu holds a patent for the "Preparation methods of high modulus carbon fiber (HMCF) and precursor (mesophase pitch (MP)) thereof." This patent outlines a comprehensive method for producing high-quality mesophase pitch, which serves as a precursor for HMCFs. The preparation method involves separating components with a molecular weight distribution of 400 to 1,000 from heavy oil using size-exclusion chromatography. The components are then processed through ion-exchange chromatography to remove acidic and alkaline substances, followed by thermal polycondensation and carbonization. The resulting mesophase pitch exhibits high mesophase content, low softening point, low viscosity, and excellent spinnability, making it an ideal raw material for HMCFs.
