Methods for making emulsifiers, emulsified drilling fluids, and methods for using the same are provided. In one or more embodiments, the method for making an emulsifier can include mixing a tall oil and a triamide. The triamide can have the chemical formula:   

Methods for producing emulsifiers for oil-based drilling fluids

Methods for making carbon materials are provided. In at least one specific embodiment, the method can include combining one or more polymer precursors with one or more liquids to produce a mixture. The mixture can be an emulsion, dispersion, or a suspension. The liquid can include hexane, pentane, cyclopentane, benzene, toluene, o-xylene, m-xylene, p-xylene, diethyl ether, ethylmethylketone, dichloromethane, tetrahydrofuran, mineral oils, paraffin oils, vegetable derived oils, or any mixture thereof. The method can also include aging the mixture at a temperature and time sufficient for the polymer precursor to react and form polymer gel particles having a volume average particle size (Dv,50) of the polymer particles in gel form greater than or equal to 1 mm. The method can also include heating the polymer gel particles to produce a carbon material.

Preparation of polymeric resins and carbon materials

Methods for making composite products are provided. In at least one specific embodiment, the method can include combining a plurality of lignocellulose substrates and one or more free radical precursors to produce a mixture of the lignocellulose substrates and the one or more free radical precursors. The method can also include maintaining the mixture at a temperature less than 60&#xb0; C. for at least 10 minutes while retaining at least 11 wt % of the one or more free radical precursors charged to the mixture. The method can then include heating the mixture comprising at least 11 wt % of the one or more free radical precursors charged to the mixture to a temperature of at least 60&#xb0; C. to about 300&#xb0; C. to produce a composite product. The composite product can have a density less than 1 g/cmand an internal bond strength of at least 0.35 MPa.

Methods for making lignocellulose containing composite products

The present invention relates to the beneficiation of coal by the process of froth flotation and specifically relates to a process for the froth flotation of coal using a mixture of fatty acids and rosin acids (and/or certain derivatives of fatty acids and rosin acids) as a collector.

Method for the benificiation of coal

The present application is directed to methods for preparation of polymer particles in gel form and carbon materials made therefrom. The carbon materials can have enhanced electrochemical properties and find utility in any number of electrical devices, for example, as electrode material in ultracapacitors or batteries.

Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, or kaolin clay) to remove impurities such as sand. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

Amine-aldehyde resins and uses thereof in separation processes

Methods for making composite products are provided. In at least one specific embodiment, the method can include combining a plurality of lignocellulose substrates, a free radical precursor, and a polyphenolic material to produce a mixture. The polyphenolic material can be in a liquid form, a solid form, or both when combined to produce the mixture. The method can also include maintaining the mixture at a temperature of less than 60&#xb0; C. for at least 10 minutes while retaining at least 11 wt % of the free radical precursor charged to the mixture. The mixture can also include heating the mixture comprising at least 11 wt % of the free radical precursors charged to the mixture to a temperature of at least 60&#xb0; C. to about 300&#xb0; C. to produce a composite product.

Collectors for froth flotation including oxidized fatty acid compositions and oxidized and maleated compositions. In particular, use of oxidized tall oil compositions and oxidized and maleated fatty acid compositions are disclosed.

Collectors

Methods for purifying one or more value materials are provided. The method can include contacting an aqueous mixture comprising a value material and a contaminant with a dispersant and a depressant to produce a treated mixture. A weight ratio of the dispersant to the depressant can be from about 1:1 to about 30:1. The method can also include recovering a purified product comprising the value material from the treated mixture. The purified product can have a reduced concentration of the contaminant relative to the aqueous slurry.

Processes for the separation of ores

Collector compositions and methods for making and using same to purify one or more crude materials are provided. The collector composition can include one or more amidoamines having the chemical Formula I and one or more amines having the chemical Formula IV, where a weight ratio of the amidoamine to the amine can be about 99:1 to about 1:99.

Collector compositions and methods for making and using same

An aqueous binder composition, useful for making fiber products, especially fiberglass insulation, comprising an aqueous substantially alkaline (pH of at least 5.0) solution of a polyol and a hydrolyzed (solubilized) copolymer of maleic anhydride and a vinyl aromatic compound, preferably styrene (i.e., a SMA copolymer); the copolymer is solubilized using ammonia, an ammine, a primary alkanolamines (preferably monoethanolamine), a secondary alkanolamine (preferably diethanolamine (DEA)), a tertiary alkanolamine (preferably triethanolamine (TEA)), or a mixture thereof and the binder composition is cured as a consequence of cross-linking, esterification reactions between pendant carboxyls on the solubilized (hydrolyzed) copolymer (SMA) chains and hydroxyl groups of the polyol, including the diethanolamine and/or triethanolamine preferably used in the solubilization of the SMA.
