  • Publication number: 20210242462
    Abstract: A method of manufacturing biomass hard carbon contains: step 1: mixing a carbon source and a nanoscale powder so as to obtain a precursor; step 2: disposing the precursor in an oxygen-free environment; step 3: carbonizing the precursor by a heating process so as to make the precursor be transformed into a hard carbon mixture; step 4: rinsing the hard carbon mixture by an acid solution, such that the hard carbon mixture has a pH value less than 0.5; step 5: modulating the pH value to be greater than 6 by using a pure water to rinse the hard carbon mixture; and step 6: producing a biomass hard carbon by drying the hard carbon mixture.

  • Patent number: 10807873
    Abstract: The invention provides a method for making multiporous carbon material from a bio-oil produced by a biomass thermochemical process. The bio-oil is blended with a resin and a Zinc Oxide (ZnO) template as a major component of a precursor. The pore sizes of the carbon material made by the invention comprise mesopores and micropores to form the multiporous carbon material. The main production steps include: (1) mixing the precursor with a crusher, (2) packing the precursor, (3) heating for carbonization: holding 350° C. for 1 hour then holding 900° C. for 2 hours, and (4) washing the ZnO with hydrochloric acid by adjusting the pH value to less than 1.
