Latest Patents

One of his latest patents is titled "Ambient temperature pulp bleaching with peroxyacid salts." This invention relates to a Kraft pulp bleaching stage that occurs after conventional bleaching stages to achieve high brightness. It has been discovered that ambient-temperature bleaching with inorganic peroxy acid salts, such as peroxymonosulfates, can significantly increase pulp brightness without causing substantial decreases in pulp viscosity. The process is conducted at ambient temperature, not exceeding about 40°C, and at an initial pH that is slightly alkaline, preferably around 7.25.

Another significant patent is the "Process for ozone bleaching of oxygen delignified pulp while conveying." This process allows for delignifying and bleaching lignocellulosic pulp without using elemental chlorine or chlorine-containing compounds. The method involves oxygen delignifying the pulp to a K No. of about 14 or less and a viscosity greater than about 10 cps. The pulp is then further delignified by lifting, displacing, and tossing it in a radial direction while advancing it axially with an effective amount of ozone. This innovative approach results in a substantially delignified pulp with a K No. of about 6 or less, a viscosity of at least about 7 cps, and a GE brightness of at least about 35. The final product can achieve a GE brightness of at least about 75, or even up to about 83 or more, by contacting the ozonated pulp with chlorine dioxide or a peroxide compound.
