    摘要： A method is provided for hydrovisbreaking hydrocarbon polymers, particularly those derived from scrap articles, in which a mixture of at least one hydrocarbon polymer and a solvent is contacted with hydrogen under conditions sufficient to hydrovisbreak the polymer. The solvent comprises a combined weight percentage of C.sub.n H.sub.2n-8 and C.sub.n H.sub.2n-10 hydrocarbons of at least about 10 weight percent, where n is an integer of at least 8 in C.sub.n H.sub.2n-8 and n is an integer of at least 10 in C.sub.n H.sub.2n-10. The hydrovisbroken polymer can be fed to a catalytic cracker for cracking to cracked products.

    摘要： A method of screening catalysts for liquid-phase selective hydrogenation by preparing a test catalyst by adding a promoter to a reference catalyst; preparing a liquid reactant stream comprising C2H2 dissolved in n-methyl-2-pyrrolidone; testing the test and reference catalysts by contacting the reactant stream and gas mixture comprising hydrogen and carbon monoxide in continuous flow with the test catalyst and reference catalyst, respectively, at selective hydrogenation reaction conditions to produce a product stream, condensing substantially all of the n-methyl-2-pyrrolidone from the product stream; measuring the concentrations of products comprising C2H2, C2H4, and C2H6 in the product stream at steady state; determining performance parameters for the test catalyst and the reference catalyst comprising the respective C2H2 conversion Sc and C2H4 selectivity relative to C2H6 Ss; and comparing the test catalyst performance parameters to those for the reference catalyst.

    摘要： The invention provides methods of recovering a pore-forming agent from an inorganic material that defines a plurality of mesopores having a controlled cross sectional area to form a mesostructure having long-range crystallinity and also to methods of making one or more mesostructures that features removal, recovery, and/or reuse of the pore-forming agent. Suitable pore-forming agents include, for example, surfactants.
