  • Patent number: 5626637
    Abstract: A process is disclosed for storing gaseous hydrocarbon fuel in storage containers under relatively low pressure by including in the cylinders highly microporous carbons prepared by further chemical activation of activated carbon comprising activation an active carbon precursor material with an alkali solution, predrying the blend to below about 25% moisture content, heat treating this blend at from about 652.degree. to about 1100.degree. C., and acid washing and drying the microporous activated carbon product, which is characterized by greater than 50% of its total pore volume comprising pores of from above 8 .ANG. to 20 .ANG. in width and greater than 70% of its total pore volume comprising pores of less than 20 .ANG. in width and greater than 95% of its total pore volume comprising pores of less than 50 .ANG. in width.
    Type: Grant
    Filed: March 14, 1995
    Date of Patent: May 6, 1997
    Assignee: Westvaco Corporation
    Inventor: Frederick S. Baker
  • Patent number: 5416056
    Abstract: A two-stage process for chemical activation of lignocellulose-derived carbon is disclosed comprising a first activation stage of blending a lignocellulose material with phosphoric acid, carbonizing the blend at from about 300.degree. F. to about 1,100.degree. F. (about 150.degree.-590.degree. C.), and water washing the carbonized material and a second activation stage of blending the carbonized material with a potassium hydroxide solution, activating this blend at from about 1,200.degree. to about 1,800.degree. F. (about 650.degree.-980.degree. C.), and water washing and drying the microporous activated carbon product, which is characterized by greater than 50% of its total pore volume comprising pores of less than 16 .ANG. in width and greater than 80% of its total pore volume comprising pores of less than 20 .ANG. in width and greater than 95% of its total pore volume comprising pores of less than 50 .ANG. in width.
