5520894 PROCESS FOR REMOVING CARBON DIOXIDE REGENERATIVELY FROM GAS STREAMS Heesink Albertus B; Temmink Herman M G, Deventer, NETHERLANDS assigned to Nederlandse Grganisatie Voor Toegepast-Natuurwetenschappelijk Onderzoek Tno PCT No. PCTiNL93/00136 Sec. 371 Date Dec. 23, 1994 Sec. 102(e) Date Dec. 23, 1994 PCT Filed Jun. 30, 1993 PCT Pub. No. WG94/01203 PCT Pub. Date Jan. 20, 1994. A process for removing carbon dioxide regeneratively from a hot gas stream, containing flue gases or fuel gases, wherein the gas stream is successively: (a) used for heating and/or desorbing a solid absorbent loaded with carbon dioxide; (b) optionally used for generating energy ; (c) passed through an absorber in which carbon dioxide from the gas stream is absorbed on the absorbent, and: (d) is discharged; and wherein: (e) the absorbent from step (c) is desorbed in ta desorber at least partially and optionally under elevated pressure and is then returned to step (c). A system for carrying out the process is also described. The process and the system are suitable for removing carbon dioxide from combustion gases and for shifting (coal) gasification gases toward hydrogen.

paper can be relatively easily recycled and reused without the normal problems associated with recycling of vat-dyed tinted papers. The surface printing can be accomplished by printing a random spotted pattern on the paper to provide for the perception of tinting. The invention allows the printed pattern to have a random-toned effect or allows the visual incorporation of words or symbols which would very subtly appear, macroscopically, in the tinting pattern.
5521008 MANUFACTURE OF ACTIVATED CARBON FIBER Lieberman Alexander I; Pimenov Alexander; Gorokhov Nicholas; Shmidt Joseph; Lieberman Leonid, St Petersburg, assigned to Electrophor Inc Activated carbon fiber is made by pm-treating a carbonized fibrous material, preferably a carbonized cellulose fiber, with a solution of nitrogen-containing compound, comprising at least one of the following substances: urea, ammonium carbonate, ammonium bicarbonate, ammonium acetate, and other organic salts of ammonia such as formate, carbamate, citrate and oxylate, and activating the pre-treated carbonized material at 8OO”to 1200°C in an atmosphere comprising steam and/or carbon dioxide until a high degree of activation is produced. The activated carbon fiber material is amphoteric, wherein both acidic and basic functional groups are present on its surface. The resulting material is suitable for removing organic impurities, cations and anions from water and other fluids.
Osajima Yutaka; Shimoda Mitsuy; Kawano Tamotsu Fukuoka, JAPAN assigned to Nippon Tansan Co Ltd The quality of a liquid foodstuff is modified by contacting it with micron-size carbon dioxide particles in a supercritical state. These particles are generated by supplying supercritical carbon dioxide through a filter with a mesh size of not more than 100 mum in average diameter. The liquid foodstuff was processed and contacted with carbon dioxide particles in a treating tank.
5520989 RECYCLABLE PRINT-TINTED PAPER Podosek Edward, Wilbraham, MA, UNITED STATES assigned to Avery Dennison Corporation A sheet of writing paper which is white, but which has been colored, or tinted to a pastel color by printing on its surface with a strippable or chemically removable ink. The surface printing with ink allows the paper to have a desirable tinted color, but allows the color to be easily removed so that the
5521305 RECYCLING MATERIALS COMPRISING CELLULOSIC AND SYNTHETIC FIBERS Huber Bemd; Stein Gerhard, Kelheim, GERMANY assigned to Hoechst Aktiengesellschaft Recycling materials comprising cellulosic and synthetic fibers Described is a process for recycling materials comprising fiber mixtures comprising cellulose fibers, comprising the steps of: (i) providing fiber mixtures comprising cellulosic fibers and fibers composed of synthetic polymers, and (ii) subjecting these mixtures to a microbial hydrolysis in which the cellulosic fibers are completely degraded. The process makes it possible in particular to separate fiber mixtures. For this, the microorganisms and the hydrolyzate are removed in a conventional manner following step (ii), and the remaining synthetic polymers are carried off in a conventional manner to be further recycled.
