摘要： A feed mixture comprising at least one C3 olefin and/or at least one C4 olefin may be contacted with a zeolite catalyst under oligomerization reaction conditions to form a product mixture comprising a plurality of olefin oligomers comprising C12 and/or C16 olefin oligomers having an average branching index, as measured by gas chromatography, of about 2.2 or less, such as about 1.3 to about 2.0. The olefin oligomers may be contacted with a syngas mixture comprising carbon monoxide and hydrogen in the presence of a hydroformylation catalyst to form a hydroformylation reaction product, which may be subsequently reduced to form a plurality of branched alcohols. The branched alcohols, in turn, may be converted into an amphiphilic compound, such as a plurality of branched alcohol sulfates.

摘要： Catalytic compositions and processes for depolymerizing polyolefin-based feed into useful petrochemical products are described. The compositions are a composite of a zeolite catalyst component and a co-catalyst comprising an activated clay component and/or a solid base component. These catalyst systems, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of impurities that may be present in the polyolefin-based feed. This results in a shorter residence time in the depolymerization unit and more efficient process.

摘要： The present disclosure provides a method of preparing olefins from methanol, in which methanol and phenol-like molecules are used as raw material, which is gasified and then passed into a two-stage fixed-bed catalytic reactor. The raw material reacts with a catalyst A (silica-aluminum molecular sieve) and a catalyst B (silica-aluminum or phosphorus-aluminum molecular sieve) in sequence to produce ethylene.

摘要： A method for preparing liquid fuel by direct conversion of syngas uses the syngas as reaction raw material and conducts a catalytic conversion reaction on a fixed bed or a moving bed. The catalyst is a composite catalyst formed by compounding component I and component II in a mechanical mixing mode. The active ingredient of the component I is a metal oxide, and the component II is at least one of zeolites with one-dimensional ten-membered ring porous channels; and a weight ratio of the active ingredient in the component I to that in the component II is 0.1-20. The reaction process has high product yield and selectivity. The selectivity for liquid fuel composed of C5-C11 can reach 50-80%. The selectivity for aromatic hydrocarbon is less than 40% in C5-C11, while the selectivity for methane side product is less than 15%.

摘要： Methods for synthesizing a nano-sized zeolite beta are described. The method may include mixing alumina and tetraethylammonium hydroxide to form an aluminum solution; mixing silica, additional TEAOH, and water to form a silica slurry; and adding the aluminum solution into the silica slurry and mixing to form an aluminosilicate gel. The method may further include transferring the aluminosilicate gel to an autoclave operated at 120° C. to 160° C. for 2 to 4 days at a rotational speed of 60 to 100 rotations per minute to form a zeolite precursor colloid; washing the zeolite precursor colloid with water to form a washed colloid; drying the washed colloid at 80° C. to 150° C. for 6 to 24 hours to form a zeolite precursor; and calcining the zeolite precursor at 400° C. to 650° C. for 2 to 8 hours to form the nano-sized zeolite beta.
