摘要： Aromatic alcohol-lignin-aldehyde resins and process for making and using same. In some examples, a process for making a resin can include heating a first mixture that includes a lignin, an aromatic alcohol, and a base compound to produce a second mixture that can include an activated lignin, the aromatic alcohol, and the base compound. The second mixture can be heated with an aldehyde to produce a third mixture that can include an aromatic alcohol-lignin-aldehyde resin and unreacted free aldehyde. In some examples, an aromatic alcohol-lignin-aldehyde resin can be or include a co-polymer of an activated lignin, an aromatic alcohol, and an aldehyde. A weight ratio of the activated lignin to the aromatic alcohol can be about 20:80 to about 95:5.

摘要： Methods and systems for recovering terpenes and controlling the composition of terpenes collected from wood drying processes are provided. In particular, a sorbent having adsorbed materials, including terpenes, from a wood drying process can be desorbed in a desorber, resulting in a gaseous stream containing terpenes, which can be condensed and collected from the gaseous stream. The conditions of desorption can be controlled to ensure a desirable amount of alpha-pinene and beta-pinene relative to other terpenes, such as dipentene and camphene, in the collected terpenes.

摘要： Methods of preparing a three-dimensional structure are provided. One method includes the steps of extruding beads of thixotropic thermoset materials, and subjecting the beads to curing conditions such that the thixotropic thermoset materials at least partially cure to form cured polymer layers. In some cases, the curing conditions are not applied until multiple beads are extruded and in contact with one another. The steps of these methods can be performed repeatedly as desired to prepare a three-dimensional structure of nearly limitless shapes by additive manufacturing processes. Thixotropic thermoset materials are also provided, as are three-dimensional objects formed therefrom.

摘要： Binder compositions and methods for making and using same are provided. In at least one specific embodiment, the binder composition can include at least one unsaturated compound having two or more unsaturated carbon-carbon bonds and at least one free radical precursor. At least one of the unsaturated carbon-carbon bonds can be a pi-bond that is not conjugated with an aromatic moiety and can be capable of free radical addition. The free radical precursor can be present in an amount of about 7 wt % to about 99 wt %, based on the weight of the one or more unsaturated compounds.

摘要： 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: where: x, y, and z are integers independently selected from 1 to 10, R1 is a C8-C20 alkyl, a C8-C20 alkenyl, a C8-C20 dialkenyl, or a C8-C20 alkynyl, R2 is H or independently selected for each [(CH2)xNR2(CH2)y] unit, where R4 is a C1-C3 alkylene or a C1-C3 alkylene alcohol, and where at least one R2 is and R3 is a C8-C20 alkyl, a C8-C20 alkenyl, a C8-C20 dialkenyl, or a C8-C20 alkynyl.

摘要： 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.

摘要： Wet strengthened fiber products, wet strengthening resins, and methods for making such wet strengthened fiber products and wet strengthening resins. The wet strengthened fiber product can include a fiber web and an at least partially cured wet strengthening resin, which prior to at least partially curing, the wet strengthening resin can include a polyamide-epihalohydrin (PAE) resin and a cationic styrene maleimide (SMI) resin. The PAE resin can include a reaction product of a polyamidoamine and an epihalohydrin and the cationic SMI resin can include a reaction product of a styrene maleic anhydride (SMA) copolymer and an amine. The wet strengthened fiber product can include the wet strengthening resin in an amount of about 0.05 wt % to about 5 wt %, based on a dried weight of the wet strengthened fiber product.

摘要： Spray dried emulsifier compositions are described, which have desirable emulsifying and wetting characteristics. Among other advantages, the solid particulate emulsifier compositions greatly reduce transportation costs and simplify the logistics and environmental concerns associated with shipping large volumes of solvent-containing liquids. The emulsifier comprises (1) a carboxylic acid terminated fatty amine condensate or (2) a modified tall oil or (3) a blend of (1) and (2) that is converted to its alkali or alkaline earth metal salt and spray dried.
