The invention relates to the preparation of novel bi- or tri metallic silicate micro-porous and/or meso-porous materials based on cerium, nickel, copper and/or zinc on a porous silicate framework matrix to use its molecular sieve effect to target preferentially the acidic organic molecules present in hydrocarbon feedstocks like crude oil, bitumen, VGO and the like. The chosen metals are selected based on their ability to activate steam and transfer oxygen for completing the oxidation of carboxylic compounds or decarboxylating them. These composite materials can be prepared under hydrothermal synthesis conditions in order to produce suitable porous solids where the metals are well dispersed and preferentially distributed inside the channels of the silicate framework where they can interact only with the molecules that can go inside the channels. According to the invention, the metallo-silicate materials are prepared under hydrothermal synthesis conditions Modification of the physical-chemical properties of the porous silicate materials can be accomplished by partial replacement of the silicon atoms by cerium, nickel, copper and/or zinc atoms in the material by isomorphous substitutions of these elements in a synthesis gel or by post-synthesis modifications like ion-exchange or impregnation/deposition.

Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks

Автор: Falkowski Joseph M., Majano Gerardo J.
Принадлежит:

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 from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling. 1. A method comprising:providing a substantially solid mixture comprising a metal salt and a multidentate organic ligand; andmulling or milling the substantially solid mixture for a sufficient length of time to produce a powder-form precursor of a metal-organic framework, the powder-form precursor being substantially free of the metal-organic framework and comprising a reaction product of the metal salt and the multidentate organic ligand.2.

Systems and methods are provided for improving separation of gas phase streams using an adsorbent, such as 8-member ring zeolite adsorbents or DDR type zeolite adsorbents. Suitable gas phase streams can include at least one hydrocarbon, such as methane or a hydrocarbon containing at least one saturated carbon-carbon bond, and at least one additional component, such as CO 2 or N 2 . The selectivity of the adsorbent is improved by selectivating the adsorbent with one or more barrier compounds. The presence of the barrier compounds is believed to alter the relative ability of potential adsorbates to enter into and/or move within the pores of the adsorbent.

(canceled) The present application claims priority to and the benefit of U.S. Provisional Application No. 61/740,917 filed on 21 Dec. 2012, which is hereby incorporated by reference in its entirety.This invention relates to the synthesis of ZSM-5, and to the use of the resultant ZSM-5 as an adsorbent and a catalyst for organic conversion reactions.Crystalline ZS M-5, and its conventional preparation using tetrapropylammonium cations as a structure directing agent, are taught by U.S. Pat. No. 3,702,886 and U.S. Pat. No. Re. 29,948, the entire disclosures of which are incorporated herein by reference. Conventional ZSM-5 has a distinctive X-ray diffraction pattern which distinguishes it from organic conversion reactions.In addition to tetrapropylammonium cations, a large number of other organic nitrogen compounds, including certain diquaternary ammonium compounds, have been shown to direct the synthesis of ZSM-5. For example, U.S. Pat. No. 4,585,638 discloses that the synthesis of ZSM-5 can be directed by the diquaternary cation (alkyl)N(CH)N(alkyl), where the alkyl group is propyl or butyl.According to the present invention, it has now been found that ZSM-5 can be synthesized using certain novel bis(N-pentylpyrrolidinium)-diquat-n cations, where n=4, 5 or 6, as a structure directing agent. The ZSM-5 can be made across a wide range of Si/Al ratios (infinity to 12) and, in some cases, it has been found that novel ultra-small forms of ZSM-5 can be produced.In one aspect, the invention resides in a process for producing a molecular sieve having the framework structure of ...

Methods are provided for synthesizing ZSM-58 crystals with an improved morphology and/or an improved size distribution. By controlling the conditions during synthesis of the ZSM-58 crystals, crystals of a useful size with a narrow size distribution can be generated. Additionally, by controlling the ratio of water content to silica content in the synthesis mixture, it has unexpectedly been found that ZSM-58 crystals can be formed with an improved morphology. The improved morphology can result in ZSM-58 crystals with a more uniform size across the various dimensions of the crystal, which allows for more uniform diffusion within the crystal. This is in contrast to conventionally synthesized crystals, where the size of the crystal can vary along different axes of the crystals.
