Injection of polymer solutions has been recognized as an effective means to improve oil recovery. To provide a comparative evaluation of the influence of water-soluble polymer on the flow behavior and...
Adsorption of Hydrocarbons and Formation of Carbocations over Zeolites Studied by IR Spectroscopy
Zeolite catalyst IR Alkene Carbocation Adsorption
2009/8/4
Carbocation species are considered to be important intermediates in the reactions of hydrocarbons over zeolites, and the formation mechanism, as well as the reactivity, has been studied mainly by NMR...
Room Temperature Sulfur Removal from LPG with Adsorbent for Fuel Cell Application — Adsorption Behavior of Sulfur Compounds —
Adsorptive sulfur removal β zeolite Ceria Fuel cell LPG
2009/7/28
LPG contains 5-10 volppm of sulfur compounds such as thiols, sulfides, and disulfides. Use of LPG as the hydrogen source for fuel cells will require the removal of sulfur content to the ppb level. Act...
