Gas Purification Process Utilizing Engineered Small Particle Adsorbents

Номер: US20120222555A1
Автор: Daniel P. Leta, Harry W. Deckman, Ramesh Gupta
Принадлежит: ExxonMobil Research and Engineering Co

A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.

Method for the adsorptive drying of purified biogas and for regenerating laden adsorbents

Номер: US20130000486A1
Автор: Lothar Guenther
Принадлежит: DGE Dr Ing Guenther Engineering GmbH

In a method for adsorptively drying purified biogas and regenerating laden absorbents, foreign matter is not allowed to enter the purified biogas, the content of methane in the gas remains virtually unchanged and the effort involved in regenerating the laden adsorbent is reduced. Drying and regeneration are effected in a closed biogas cycle, wherein separate layers based on silica gel and molecular sieves are used as the adsorbent. The biogas to be dried first flows through the silica gel layer. The adsorbent is regenerated with exclusively heated, dried biomethane having a temperature of up to 150° C. which, after contact with adsorbent, is recirculated to the outflow of purified biogas. After regeneration, the bed is cooled by biomethane, which is subsequently recirculated to the outflow of purified biogas. Methane-containing water accumulating during drying and regeneration is recirculated to the biogas generation and/or purification.

Catalytic adsorbents obtained from municipal sludges, industrial sludges, compost and tobacco waste and process for their production

Номер: US20130102456A1
Автор: Teresa J. Bandosz
Принадлежит: Research Foundation Of City University of New York

Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers.

Overcoming two carbon dioxide adsorption steps in diamine-appended metal-organic frameworks

Принадлежит: ExxonMobil Research and Engineering Co, UNIVERSITY OF CALIFORNIA

Primary, secondary (1º,2º) alkylethylenediamine- and alkylpropylenediamine-appended variants of metal-organic framework are provided for CO2 capture applications. Increasing the size of the alkyl group on the secondary amine enhances the stability to diamine volatilization from the metal sites. Two-step adsorption/desorption profiles are overcome by minimizing steric interactions between adjacent ammonium carbamate chains. For instance, the isoreticularly expanded framework Mg2(dotpdc) (dotpdc4−=4,4″-dioxido-[1,1′:4′,1″-terphenyl]-3,3″-dicarboxylate), yields diamine-appended adsorbents displaying a single CO2 adsorption step. Further, use of the isomeric framework Mg-IRMOF-74-II or Mg2(pc-dobpdc) (pc-dobpdc4−=3,3-dioxidobiphenyl-4,4-dicarboxylate, pc=para-carboxylate) also leads to a single CO2 adsorption step with bulky diamines. By relieving steric interactions between adjacent ammonium carbamate chains, these frameworks enable step-shaped CO2 adsorption, decreased water co-adsorption, and increased stability to diamine loss. Variants of Mg2(dotpdc) and Mg2(pc-dobpdc) functionalized with large diamines such as N-(n-heptyl)ethylenediamine have utility as adsorbents for carbon capture applications.

A system and method for producing a modified coal ash involves collecting a bulk quantity of such coal ash, generally after it has been produced or landfilled, or is otherwise at temperatures closer to ambient, as opposed to power plant operational temperatures. In one possible implementation, the method herein involves removing carbon from the coal ash, such removal occurring by exposing the carbon to indirect heat, that is, externally-applied heat. For coal ashes with higher ash content. This removal is accomplished by subjecting the coal ash stream to heat, in one implementation, ranging between 850° F. and 1200° F., and such heat exposure occurring from about 10 minutes to about 30 minutes. The range of exposure time for the coal ash is determined so as to reduce the LOI from its initial level to a level acceptable for intended re-use or recycling. In one application, the LOI of carbon in the ash is reduced to 3% or less carbon. Upon completion of the range of the exposure time, the coal ash stream is removed from the sublimation heat, thereby forming a modified coal ash. 1.

A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.

CATALYTIC ADSORBENTS OBTAINED FROM MUNICIPAL SLUDGES, INDUSTRIAL SLUDGES, COMPOST AND TOBACCO WASTE AND PROCESS FOR THEIR PRODUCTION

Номер: US20160236146A1
Автор: Bandosz Teresa J.
Принадлежит: RESEARCH FOUNDATION OF THE CITY UNIVERSITY OF NEW YORK

Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers. 2. The process of claim 1 , wherein the acidic gases are one or more of hydrogen sulfide claim 1 , sulfur dioxide claim 1 , hydrogen cyanide claim 1 , and nitrogen dioxide.3.
