Latest Patents

One of his latest patents is for polysaccharide-based porous sheets. This invention involves a microporous sheet comprising a polymeric matrix with a liquid insoluble, particulate, activated polysaccharide media dispersed within it. The sheet can be utilized in affinity chromatography, ion-exchange chromatography, as a biochemical reactor, or as a battery separator. Additionally, the patent outlines processes for manufacturing the sheet, apparatus containing the microporous sheet as its active element, and methods for using such a sheet. Another significant patent by Gray is for the manufacture of cyanuric acid. In this process, waste digester liquor containing dissolved triazines and iron is treated with ammonia until the pH reaches about 2.5 to 4, precipitating most of the triazines while leaving most of the iron in solution. The triazines are then separated and recycled back to the digester, while the filtrate of ammonium salts serves as a useful source of fertilizer nitrogen.
