摘要: Method of making porous, fibrillose bodies from fibrils bonded together into a self-supporting structure. A mixture of fibrils and a viscous, non-newtonian, liquid vehicle including an organic hydrosorbent and water is (1) injected into a mold, (2) frozen in the mold to form a frozen precursor of the article, (3) ejected from the mold while still frozen, (4) freeze-dried, and (5) finally heated to remove the hydrosorbent and bond the particles together. The process is particularly effective for making fibrillose preforms for infiltrating with metal in the manufacture of metal matrix composites.

摘要: Ozone and, if necessary, water is added to an exhaust gas, such as air, containing hydrogen- and carbon-containing molecules of a pollutant. The exhaust gas is then continually flowed into one or more oxidizing reaction chamber modules. In the reaction chamber(s) the ozone- and water-containing gas is subjected to intense ultraviolet radiation (wavelength of 254 nm) to promote the formation of hydroxyl radicals to oxidize the pollutant molecules to carbon dioxide and water. The continually discharged gas is analyzed for residual ozone and hydrocarbon content and the analytical data used in feedback control of ozone addition and UV radiation intensity.

摘要: The nitric oxide (NO) and nitrogen dioxide (NO2) content of lean-burn engine exhaust is beneficially prepared for selective catalytic reduction (SCR) of these oxides to nitrogen by two sidestream additions to the exhaust. An ozone-containing air stream is added to the exhaust to affect oxidation of NO to NO2. And a hydrocarbon(s) fuel constituent is added to a second humidified ozone-containing air stream and that mixture subjected to UV radiation. Strongly oxidizing hydroxyl radicals are formed by interaction of ozone, water, and UV radiation for reaction with the hydrocarbon. The resulting partially oxidized hydrocarbons (Pox) are added to the exhaust, providing effective reduction materials for the SCR of NO2 to nitrogen and water.
