    摘要： A sorbent material, an activated carbon canister and a method are described which can be utilized to remove organic compounds from a vaporous stream with a relatively greater degree of safety, as compared to previously known methods. In the invention, essentially dry and wetted activated carbon particles are intermixed in a substantially homogeneous mixture which inhibits accidental combustion. The heat capacity of wetted carbon particles retards the heating of nearby unwetted particles, so as to inhibit the ignition of the nearby unwetted particles. The presence of wetted particles intermixed in the substantially homogeneous mixture has relatively little effect on the hydrocarbon adsorption performance of the mixture.

    摘要： A method is disclosed for preparing a supported hydrogenation metal catalyst containing one each of Mo or W and of Co and/or Ni incorporated into a suitable support. An aqueous impregnating solution containing the desired quantity of catalytically active metals and having a pH in the range of about 0.7-2.7 is prepared containing (1) at least one each of a soluble compound of molybdenum or tungsten and a compound of cobalt and/or nickel; (2) a solubilizing amount of about 0.2-1.0 mole of phosphorous per mole Mo or W; and (3) about 2-6% w basis support, of a suitable soluble amine compound, such as amine alcohols, polyamines and amine acids. A suitable support, e.g., alumina, silica or silica-alumina, is then impregnated with the metals-containing solution. After impregnation the support is dried and calcined. This preparation method significantly increases the hydrodenitrification activity of the resulting catalyst in a hydrocarbon hydroconversion process.
