Latest Patents

One of his latest patents is titled "Minimizing chlorinated organics in pulp bleaching processes." This invention relates to methods for reducing the amount of halogenated organics produced during a halogen bleaching process for lignocellulosic pulp fibers. The disclosed invention reveals that using a chelating agent prior to a non-halogen containing bleaching stage effectively increases the brightness of the resulting bleached pulp. This method does so without requiring an increase in the amount of halogen compounds, thus maintaining pulp viscosity and yield.

Another significant patent is the "Two phase ozone and oxygen pulp treatment." This improvement involves a two-phase process in the post-digestion treatment of kraft cellulosic pulp. Each phase includes contacting the pulp first with an ozone/oxygen mixture at a temperature below about 60°C, followed by oxygen treatment at a temperature above about 65°C.
