Abstract
Methods of applying a sorbent coating on a substrate, a support, and/or a substrate coated with a support are described. One of the methods comprises: (i) optionally, preparing the substrate coated with the support by pre-treating the substrate with a slurry, wherein the slurry comprises: a. solvent, b. a binder, c. the support, and d. optional dispersant; and (ii) treating the substrate, the support, and/or the substrate coated with the support, with a sorbent.

A method of applying a sorbent coating on a substrate, a support, and/or a substrate coated with a support, the method comprising:
- (i) optionally, preparing the substrate coated with the support by pre-treating the substrate with a slurry, wherein the slurry comprises:
- a. solvent,
- b. a binder,
- c. the support, and
- d. optional dispersant;
- and
- (ii) treating the substrate, the support, and/or the substrate coated with the support, with a sorbent;
- wherein the substrate is (a) a monolithic or honeycomb structure made of ceramic, metal, or plastic;
- (b) a polyurethane foam, a polypropylene foam, a polyester foam, a metal foam, or a ceramic foam;
- or (c) woven or non-woven plastic or cellulosic fibers,
- wherein the support is alumina, silica, silica-alumina, titania, zirconia, carbon, zeolite, metal-organic framework (MOF), or combinations thereof, and
- wherein the sorbent adsorbs carbon dioxide and the sorbent is selected from the group consisting of amines;
- monoethanolamine;
- diethanolamine;
- polyethylenimine (PEI);
- aminopropyltrimethoxysilane;
- polyethyleneimine-trimethoxysilane;
- amide or amine containing polymers including nylon, polyurethane, polyvinylamine, or melamine;
- and combinations thereof.
The method of claim 9, wherein the channels are square, triangular, or sinusoidal in cross-section.
A method of applying a sorbent coating on a substrate, a support, and/or a substrate coated with a support, the method comprising:
- (i) treating the substrate, the support, and/or the substrate coated with the support, with a slurry comprising:
- a. a solvent,
- b. a binder, and
- c. the sorbent;
- wherein the substrate is (a) a monolithic or honeycomb structure made of ceramic, metal, or plastic;
- (b) a polyurethane foam, a polypropylene foam, a polyester foam, a metal foam, or a ceramic foam;
- or (c) woven or non-woven plastic or cellulosic fibers,
- wherein the support is alumina, silica, silica-alumina, titania, zirconia, carbon, zeolite, metal-organic framework (MOF), or combinations thereof, and
- wherein the sorbent adsorbs carbon dioxide and the sorbent is selected from the group consisting of amines;
- monoethanolamine;
- diethanolamine;
- polyethylenimine (PEI);
- aminopropyltrimethoxysilane;
- polyethyleneimine-trimethoxysilane;
- amide or amine containing polymers including nylon, polyurethane, polyvinylamine, or melamine;
- and combinations thereof.
An alumina support comprising a sorbent coating,
- wherein the sorbent adsorbs carbon dioxide and the sorbent is selected from the group consisting of amines;
- monoethanolamine;
- diethanolamine;
- polyethylenimine (PEI);
- aminopropyltrimethoxysilane;
- polyethyleneimine-trimethoxysilane;
- amide or amine containing polymers including nylon, polyurethane, polyvinylamine, or melamine;
- and combinations thereof, and
- wherein the alumina support has a surface area of about 150 m2/g to 250 m2/g and a pore volume of about 0.7 cc/g to 1.5 cc/g.
