摘要： Thionyl chloride is a hazardous and reactive chemical used as the liquid cathode in commercial primary batteries. Contrary to previous thinking, ASZM-TEDA® carbon (Calgon Corporation) reversibly absorbs thionyl chloride. Thus, several candidate materials were examined as irreversible getters for thionyl chloride. The capacity, rate and effect of temperature were also explored. A wide variety of likely materials were investigated through screening experiments focusing on the degree of heat generated by the reaction as well as the material absorption capacity and irreversibility, in order to help narrow the group of possible getter choices. More thorough, quantitative measurements were performed on promising materials. The best performing getter was a mixture of ZnO and ASZM-TEDA® carbon. In this example, the ZnO reacts with thionyl chloride to form ZnCl2 and SO2. The SO2 is then irreversibly gettered by ASZM-TEDA® carbon. This combination of ZnO and carbon has a high capacity, is irreversible and functions effectively above −20° C.

摘要： A process is provided for the manufacture of a carbonaceous char capable of catalyzing the rapid decomposition of hydrogen peroxide in aqueous solutions. This carbonaceous char is produced from a bituminous coal or a bituminous material that has been carbonized and extensively oxidized at low (less than 700° C.) temperatures. The resultant carbonized and oxidized bituminous coal or bituminous material is then contacted with a nitrogen-containing compound in combination with at least one of sucrose or fructose as the temperature of the low-temperature char is increased to greater than 700° C. This treatment results in a high-temperature char which may then be activated as desired. These activated chars show the aforementioned ability to rapidly decompose aqueous solutions of hydrogen peroxide and are also useful for the catalytic decomposition of H2S, SOx, NOx, chloramines, and/or peroxides in liquid and/or gaseous streams.

摘要： Microporous carbonaceous materials, useful in the storage of gaseous fuels such as methane and natural gas, are improved through modification of their microporous structure in a post-carbonization process. This modification is done by heat treatment in an oxidizing atmosphere containing carbon dioxide with or without other diluting gases such as nitrogen, argon or water-vapor. The post-carbonization process involved modifying a starting microporous carbon with heat treatment in which the carbon is contacted with a carbon dioxide-containing atmosphere. This new treatment can be favorably applied either to selected and commercially available activated microporous carbons which have been designed for applications other than fuel gas storage or to synthetic microporous carbons proposed for storage of light gases.

摘要： An odor sorbing packaging material is prepared by applying to at least one surface of a flexible substrate an odor absorbing coating containing an effective concentration of activated carbon. The packaging material may be converted into packages, bags, pouches, liner members, wrappers or the like for packaging products and other materials that generate objectionable odors.
