Abstract: A method of producing LNG. According to the method, a natural gas stream is compressed using first and second compressors. A cooler cools the natural gas stream so that the second compressor produces a cooled, compressed natural gas stream, which is liquefied in a liquefaction process. The liquefaction process uses a refrigerant compressor configured to compress a stream of refrigerant used to chill, condense, or liquefy the cooled, compressed natural gas stream. Using a heat recovery steam generation (HRSG) system, heat is recovered from a power source of the refrigerant compressor. A stream of pressurized steam is generated from the recovered heat. At least one of the first and second compressors is powered using at least part of the stream of pressurized steam.

Abstract: Methods are provided for making amine-functionalized organosilica materials that include additional amine functionalities that are grafted to the composition after the initial synthesis. Methods of using such materials are also provided. It has been discovered that additional aminosilyl groups can be grafted onto amine-functionalized organosilica materials under conditions that substantially preserve the original CO2 sorption capacity of the underlying organosilica material prior to grafting. This allows the additional amines in the grafted aminosilyl groups to increase the net capacity of the grafted material, as opposed to primarily replacing the original CO2 sorption capacity with the sorption capacity of the grafted amine functionalities.

Abstract: Compositions corresponding to amine-functionalized organosilica materials are provided, along with methods of making such materials and methods of using such materials. The amine-functionalized organosilica materials are formed in part by using a single step synthesis process based on condensation of an alkoxy-substituted cyclic organosilane precursor in the presence of an aminosilane precursor so that an amine-functionalized polymer is formed. An acyclic alkoxy silane compound can also be used during the condensation to provide a secondary monomer that facilitates formation of the gel. The amine-functionalized organosilica materials are also formed in part by using at least one of a supercritical drying process and a freeze drying process. By using a supercritical drying process and/or a freeze drying process, an amine-functionalized organosilica material can be formed that has improved properties for sorption of CO2.

Abstract: Disclosed herein are a variety of systems, compositions, and methods for reversibly storing electrical energy in a redox flow battery with a unit cell potential equal to or greater than 3.5 volts. The systems include a positive section, a negative section, and an electroactive bipolar redox molecule comprising an anolyte moiety and a catholyte moiety separated by a non-conjugating insulating linker. The catholyte moiety comprises para-dimethoxybenzene and the non-conjugating insulating linker comprises at least two -CX2 linkers, wherein X comprises at least one atom selected from the group consisting of hydrogen and heteroatoms. The positive section comprises a first metal electrode in contact with the electroactive bipolar redox molecule and a supporting electrolyte dissolved in a solvent. The negative section comprises a second metal electrode in contact with the electroactive bipolar redox molecule and additional electrolyte dissolved in additional solvent.

Abstract: An aluminosilicate zeolite may have a molar ratio of Si to Al of about 3 to about 10, a monoclinic space group C2/m with unit cell dimensions of a of 13.6 Å+/−5%, b of 21.7 Å+/−5%, c of 6.7 Å+/−5%, and β of 93°+/−3°, 12-ring pores along a c-axis having dimensions of 7 Å+/−5% by 6 Å+/−5%, and 8-ring pores along an a-axis having dimensions of 3 Å+/−5% by 3 Å+/−5%. Said aluminosilicate zeolites may be useful in hydrocarbon conversion processes, selective catalytic reduction of NOx, CO2 and/or N2 adsorption, carbonylation reactions, and the monoalkylamine and dialkylamine syntheses.

Abstract: High molecular weight elastomers, such as ethylene-propylene-diene monomer (EPDM) polymers, are conventionally formulated with a post-polymerization oil extension to mitigate their high Mooney viscosity. Post-polymerization oil extension adds to processing costs and precludes use of polymerization facilities lacking oil extension capabilities. A low molecular weight polymer may be co-produced with a high molecular weight elastomer containing the same monomers, where the low molecular weight polymer may function in place of conventional oil extension. Polymerization methods may form a polyolefin blend comprising first and second polyolefins having a bimodal molecular weight distribution.

Abstract: Processes for making propylene-based copolymers having broad molecular weight distributions and broad comonomer distributions using a single tubular reactor. Processes for making a propylene-based copolymer can include introducing propylene and at least one other olefin comonomer to a tubular reactor to produce a propylene-based copolymer having a broad comonomer distribution, a Mw of about 10 kg/mol to about 2.000 kg/mol, and a MWD of about 2.0 to about 10.0. The tubular reactor can include one or more heat exchanger elements, preferably a spiral heat exchanger. Propylene-based copolymer compositions can include propylene derived units and at least one other comonomer derived units, wherein the copolymer compositions have a broad comonomer distribution, a Mw of about 10 kg/mol to about 2.000 kg/mol, and a MWD of about 2.0 to about 10.0. Such compositions can have broad orthogonal comonomer distributions.

Abstract: Systems and methods are provided for increasing the yield of products generated during co-processing of biomass oil in a fluid catalytic cracking (FCC) system. The systems and methods can allow for increased yield by reducing or minimizing formation of carbon oxides, gas phase products, and/or coke yields during the co-processing. This can be achieved by adding a hydrogen-rich co-feed to the co-processing environment. Examples of hydrogen-rich co-feeds include high hydrogen content vacuum gas oil co-feed, high hydrogen content distillate co-feed, and/or high hydrogen content naphtha co-feed. Additionally or alternately, various types of fractions that contain a sufficient amount of hydrogen donor compounds can be used to reduce or minimize carbon oxide formation.

Abstract: Alkylated naphthalene blendstock and processes for making the alkylated naphthalene blendstock are provided. The present processes comprise mixing an acid-form MWW-type catalyst, naphthalene, and a solvent to provide a reaction mixture and adding linear alpha olefins to the reaction mixture after heating. The resulting AN blendstock has an isomer ratio of less than 45 wt % mono alkylated naphthalene and greater than 55 wt % multi-alkylated naphthalene and can be combined with polyalphaolefin base stock to provide a synthetic lubricant formulation produced without triflic catalyst and with less process steps.
