    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: The present invention provides for a process for reducing the pour point of a hydrocarbon feedstock containing nitrogen- and sulfur-containing impurities. The hydrocarbon feedstock is contacted with hydrogen and a hydrotreating catalyst under hydrotreating conditions whereby a portion of the nitrogen- and sulfur-containing compounds are converted to hydrogen sulfide and ammonia. A portion of the hydrotreater effluent is then passed to a dewaxing zone and contacted with hydrogen under dewaxing conditions in the presence of a dewaxing catalyst containing a borosilicate molecular sieve on silica-alumina-containing matrix.

    摘要: The present invention provides for a process for reducing the pour point of a hydrocarbon feedstock containing nitrogen- and sulfur-containing compounds. Specifically, the hydrocarbon feedstock is passed to an extraction zone wherein N-Methyl-2-pyrrolidone is used to extract a portion of the aromatic compounds. A portion of the extraction zone raffinate is then passed to a hydrotreating zone wherein a portion of the nitrogen and sulfur containing compounds are converted to hydrogen sulfide and ammonia. Subsequently, a portion of the hydrotreating zone effluent is then passed to a dewaxing zone and contacted with a shape selective molecular sieve containing dewaxing catalyst.

    摘要: Disclosed is a process for the removal of hydrogen from streams comprising olefinic compounds, such as streams from a polymerization reactor. At least a portion of the olefinic compounds are saturated with a substantial portion of the hydrogen present so as to effectively remove hydrogen from the stream. The saturated material formed can be then separated from unreacted olefinic compounds by use of a membrane separator and the olefinic compounds recycled to a polymerization zone for reaction.
