The present disclosure relates to hydrocarbon emission control systems. More specifically, the present disclosure relates to substrates coated with hydrocarbon adsorptive coating compositions and evaporative emission control systems for controlling evaporative emissions of hydrocarbons from motor vehicle engines and fuel systems. The hydrocarbon adsorptive coating compositions include particulate carbon having a BET surface area of at least about 1300 m.sup.2/g, and at least one of (i) a butane affinity of greater than 60% at 5% butane; (ii) a butane affinity of greater than 35% at 0.5% butane; (iii) a micropore volume greater than about 0.2 mug and a mesopore volume greater than about 0.5 ml/g.

In general, the present disclosure is directed to a soyhull-based activated carbon. The soyhull-based activated carbon comprises a Brunauer-Emmett-Teller (BET) surface area of from about 750 m.sup.2/g to about 2900 m.sup.2/g and a micropore volume of from about 0.50 cm.sup.3/g to about 1.2 cm.sup.3/g.

The adsorption filter according to the present invention is formed from a molded body including activated carbon and a binder, the pore volume of pores having a diameter of 10 μm or greater in terms of the volume of the adsorption filter as measured through mercury intrusion being 0.10 cm.sup.3/cc to 0.39 cm.sup.3/ee.

The present invention provides novel chromatographic materials, e.g., for chromatographic separations, processes for their preparation and separations devices containing the chromatographic materials. The preparation of the inorganic/organic hybrid materials of the invention wherein a surrounding material is condensed on a superficially porous hybrid core material will allow for families of different hybrid packing materials to be prepared from a single core hybrid material. Differences in hydrophobicity, ion-exchange capacity, chemical stability, surface charge or silanol activity of the surrounding material may be used for unique chromatographic separations of small molecules, carbohydrates, antibodies, whole proteins, peptides, and/or DNA.

The present invention relates to novel sulfur-doped carbonaceous porous materials. The present invention also relates to processes for the preparation of these materials and to the use of these materials in applications such as gas adsorption, mercury and gold capture, gas storage and as catalysts or catalyst supports.

A method for separating natural gas liquids (NGLs) from a hydrocarbon gas mixture containing natural gas liquids and methane, comprising the steps of: i) providing a bed of adsorbent selective for NGLs over methane; ii) passing a hydrocarbon gas mixture containing methane and NGL through the bed of adsorbent to at least partially remove NGLs from the gas mixture to produce: (a) NGL-loaded adsorbent and (b) NGL-depleted hydrocarbon gas mixture; iii) recovering the NGL-depleted hydrocarbon gas mixture; iv) regenerating the NGL-loaded adsorbent by at least partially removing NGLs from the adsorbent; and v) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv).

The invention relates to a cyclical method for producing a nitrogen fraction, the purity of which is greater than or equal to 95 mol %, and a hydrocarbon-enriched fraction from a filler containing nitrogen and a hydrocarbon, said method using a specific class of porous hybrid solids as an adsorbent in a pressure-swing adsorption (PSA) process. The invention also relates to equipment for implementing said method.

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

To provide a filter medium, a process for producing filter medium, a filtration device, a method for operating the filtration device, and a filtration system, which are capable of promptly regenerating the adsorption power by backwashing and realizing efficient operation of a filtration device. The filter medium of the present invention contains a carbon-based material in which a cumulative pore volume of pores having a pore radius of 2 nm or less is 25% or less with respect to a cumulative pore volume of pores having a pore radius of 50 nm or less.

Some embodiments of the present disclosure relate to a device comprising a sorbent polymer composite and at least one phosphonium halide. In some embodiments, the device is configured to treat a flue gas stream. In some embodiments, the flue gas stream comprises oxygen, water vapor, at least one SOx compound, and mercury vapor. Some embodiments of the present disclosure relate to a method comprising treating the flue gas stream by: passing the flue gas stream over the device, reacting the oxygen and water vapor of the flue gas stream with the at least one SOx compound on the sorbent polymer composite, so as to form sulfuric acid, and reacting the mercury vapor with the at least one phosphonium halide, so as to fix molecules of the mercuiy vapor to the sorbent polymer composite.
