Abstract: A hydrocarbon feed stream, particularly one comprising heavier hydrocarbons, may be converted to valuable products such as motor gasoline and/or lubricating oil by employing one or more large pore zeolitic catalysts, which may be prepared from a precursor zeolite. In some examples, a large pore zeolitic catalyst may be utilized to selectively reduce the endpoint of a hydrocarbon composition.

Abstract: Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced in powder form. Extrusion of powder-form MOFs to produce shaped bodies has heretofore proven difficult due to loss of surface area and poor crush strength of MOF extrudates, in addition to phase transformations occurring during extrusion. The choice of mixing conditions and the mixing solvent when forming MOF extrudates can impact these factors. Extrudates comprising a MOF consolidated material may feature the MOF consolidated material having a BET surface area of about 50% or greater relative to that of a pre-crystallized MOF powder material used to form the extrudate. X-ray powder diffraction of the extrudate shows about 20% or less conversion of the MOF consolidated material into a phase differing from that of the pre-crystallized MOF powder material.

Abstract: A method for separating classes of hydrocarbon compounds from a feed stream including a hydrocarbon mixture is disclosed. The method includes the steps of passing a feed stream through a plurality of separation units arranged in a series in any order, wherein each separation unit has an adsorbent material; and separating classes of hydrocarbon compounds from the feed stream. When one of the plurality of separation units comprises an adsorbent material that is a metal organic framework selected from a zirconium, hafnium, cerium, or titanium-based metal organic framework, then another plurality of separation units includes an adsorption material that is different from the metal organic framework. The method is conducted in a liquid phase. The method can also use a single separation unit with a continuous cyclic bed apparatus. The method can be combined with refining and downstream processes.

Abstract: Provided herein are adsorption materials comprising a mixed-metal mixed-organic framework comprising metal ions of two or more distinct metals and a plurality of organic linkers. Each organic linker in the plurality of organic linkers is connected to a metal ion. The adsorption material further comprises a plurality of ligands. In an aspect, each respective ligand in the plurality of ligands is an amine or other Lewis base (electron donor) appended to a metal ion in the two of more distinct elements of the mixed-metal organic framework to provide a mixed-metal mixed-organic framework system.

Abstract: Polyamines with lengths carefully tailored to the framework dimensions are appended to metal-organic frameworks such as Mg2(dobpdc) (dobpdc4-=4,4′-dioxidobiphenyl-3,3′-dicarboxylate) with the desired loading of one polyamine per two metal sites. The polyamine-appended materials show step-shaped adsorption and desorption profiles due to a cooperative CO2 adsorption/desorption mechanism. Several disclosed polyamine-appended materials exhibit strong ability to capture CO2 from various compositions. Increased stability of amines in the framework has been achieved using high molecular weight polyamine molecules that coordinate multiple metal sites in the framework. The preparation of these adsorbents as well as their characterization are provided.

Abstract: Provided herein are compositions and methods for use of an organosilica material comprising a copolymer of at least one monomer of Formula [R1R2SiCH2]3 (I), wherein, R1 represents a C1-C4 alkoxy group; and R2 is a C1-C4 alkoxy group or a C1-C4 alkyl group; and at least one other monomer of Formula [(Z1O)xZ23-xSi—Z3—SZ4] (II), wherein, Z1 represents a hydrolysable functional group; Z2 represents a C1-C10 alkyl or aryl group; Z3 represents a C2-C11 cyclic or linear hydrocarbon; Z4 is either H or O3H; and x represents any one of integers 1, 2, and 3. The composition may be used as a support material to covalently attach transition metal cations, as a sorbent for olefin/paraffin separations, as a catalyst support for hydrogenation reactions, as a precursor for highly dispersed metal nanoparticles, or as a polar sorbent for crude feeds.

Abstract: Methods of synthesizing crystalline metal-organic frameworks (MOFs) comprising polytopic organic linkers and cations, where each linker is connected to two or more cations, are provided. In the disclosed methods, the linkers are reacted with a compound of formula MnXm, where M is cationic Be, Mg, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Ru, Rh, Pd, Cd, or Hf, X is anionic, n and m are integers. The reacting is buffered by a buffer devoid of metal coordinating functionality when the pKa of the anion is below a threshold related to the lowest pKa of the linker. The reacting is optionally not buffered when the pKa of the anion is at or above this threshold. The disclosed methods lead to product phase MOF in which crystal growth is controlled leading to control over molecular diffusion.
