摘要： A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

摘要： Methods are provided for forming supported catalyst compositions and/or corresponding intermediate catalyst products. The catalyst compositions have improved activity for hydroprocessing of distillate boiling range feeds under hydroprocessing conditions where the hydrogen partial pressure in the hydroprocessing environment is reduced or minimized. The catalyst compositions can correspond to supported CoMo catalysts. The improved activity for hydroprocessing under lower pressure conditions is unexpectedly achieved by using a plurality of treatments with organic compounds during the catalyst formation process.

摘要： Methods are provided for forming supported catalyst compositions and/or corresponding intermediate catalyst products. The catalyst compositions have improved activity for hydroprocessing of distillate boiling range feeds under hydroprocessing conditions where the hydrogen partial pressure in the hydroprocessing environment is reduced or minimized. The catalyst compositions can correspond to supported CoMo catalysts. The improved activity for hydroprocessing under lower pressure conditions is unexpectedly achieved by using a plurality of treatments with organic compounds during the catalyst formation process. A first treatment with an organic compound can occur prior to, during, and/or after exposing the support to metal precursors for depositing metals on the support. After both the first organic compound and the metal precursors are available in the presence of the support, a first heating and/or carbonizing step can be used to form dispersed metal carbides on the support. The first heating and/or carbonizing step can be performed at intermediate temperatures between 250° C. and 500° C., or 250° C. to 550° C., in order to maintain the metal carbides and/or the support in a favorable state. After treating the supported metal carbides with the secondary organic compound, a sulfidation can be performed where at least an initial portion of the sulfidation occurs at a temperature of 250° C. or less. This can allow the secondary organic compound to substantially remain on the support during at least a portion of the sulfidation process.

摘要： Sulfur-crosslinked olefins, particularly sulfur-crosslinked heavy hydrocarbon products having one or more sulfur-crosslinked olefin moieties, may undergo pyrolysis to form sulfur-doped porous carbon having high BET surface area values. Pyrolysis to form the sulfur-doped porous carbon may be particularly efficacious in the presence of a hydroxide base. BET surface areas up to 2000 m2/g or even higher may be obtained. Such sulfur-doped porous carbon may be prepared by combining a heavy hydrocarbon product with sulfur, heating to a first temperature state to form a liquefied reaction mixture containing a sulfur-crosslinked heavy hydrocarbon, homogeneously mixing a hydroxide base with the liquefied reaction mixture, and pyrolyzing the sulfur-crosslinked heavy hydrocarbon to form sulfur-doped porous carbon.
