Abstract: A plasma-assisted catalytic reforming apparatus includes a feeder, a plasma reactor, a reforming reactor and a pre-heater. A first reforming cavity of the reforming reactor is connected to a plasma cavity of the plasma reactor, and the reforming reactor is inside a pre-heating cavity of the pre-heater. A pre-heating pipe of the pre-heater is connected between a mixing room of the feeder and the plasma cavity and partially disposed inside the pre-heating cavity. The first reforming cavity is inside a second reforming cavity of the reforming reactor. An end of a recirculation pipe of the reforming reactor is connected to a first reforming cavity opening of the first reforming cavity and partially disposed inside the first reforming cavity. Another end of the recirculation pipe passes a second reforming cavity outlet of the second reforming cavity and partially disposed inside the pre-heating cavity. A plasma-assisted catalytic reforming method is also provided.

Abstract: A method for preparing radioactive-substance adsorbent depositing on a carriable structure is revealed. The method uses a supercritical fluid to mix a first solution with a carrier. The first solution includes an extractant dissolved in a first solvent. By low surface tension and high permeability of the supercritical fluid, the extractant in the first solution deposit evenly on the carrier so as to form an adsorbent. Thus the adsorbent formed provides better adsorptivity for the radioactive substances.

Abstract: A vermiculite supported catalyst for carbon monoxide (CO) preferential oxidation (PROX) is disclosed. The CO PROX catalyst comprises at least one catalytic agent, one optional modifier agent, one carrier material, and a vermiculite support. The process for preparing the vermiculite supported catalyst in this invention includes depositing first the carrier material on a vermiculite support followed by calcination to form the carrier-containing support, and wet impregnating the catalytic agent and the optional modifier agent on the carrier-containing support followed by drying and calcination to form the CO preferential oxidation catalyst.
