The method includes the steps of: (a) performing a first separation using a first extraction chromatographic column based on a first resin (either a diglycolamide resin or a dialkylphosphoric acid resin) and a first matrix solution; and (b) performing a second separation using a second extraction chromatographic column based on a second resin (respectively either a dialkylphosphoric acid resin or a diglycolamide resin).

The disclosure provides a method for evaluation of removal of nitrogen-containing organic matter from the wastewater. The method includes: 1) pretreating a wastewater sample from a wastewater treatment plant; enriching nitrogen-containing organic matter in the wastewater sample with a solid-phase extraction cartridge; separating the nitrogen-containing organic matter from a substrate and disruptors of the wastewater sample, and collecting the nitrogen-containing organic matter; 2) detecting and analyzing the nitrogen-containing organic matter collected in 1) with a Fourier-transform ion cyclotron resonance mass spectrometer, thereby obtaining mass spectra of the nitrogen-containing organic matter; 3) preprocessing peak data of the mass spectra of the nitrogen-containing organic matter in each wastewater sample; setting the nitrogen-containing organic matter corresponding to the peak data as a global variable; arranging wastewater samples into cross-sectional data according to wastewater treatment processes; creating an assessment matrix for evaluating removal of the nitrogen-containing organic matter.

The present disclosure relates to a composition that includes a lignin-derived mixture that includes at least one of a dimer, a trimer, and/or a tetramer, where the composition is characterized by a thermal stability up to a maximum temperature between about 260° C. and about 300° C.

Abstract: Described herein is a process for obtaining rare earth elements from coal-based resources. Advantages of this process include low energy demands, application of environmentally-friendly solvents, and high purities of obtained rare earth elements.

A process for removing heavy polycyclic aromatic contaminants from a hydrocarbon stream using a quinolinium ionic liquid is described. The process includes contacting the hydrocarbon stream comprising the contaminant with a hydrocarbon-immiscible quinolinium ionic liquid to produce a mixture comprising the hydrocarbon and a hydrocarbon-immiscible quinolinium ionic liquid comprising at least a portion of the removed contaminant; and separating the mixture to produce a hydrocarbon effluent having a reduced level of the contaminant and a hydrocarbon-immiscible quinolinium ionic liquid effluent comprising the hydrocarbon-immiscible quinolinium ionic liquid comprising at least the portion of the removed contaminant.

The present invention relates to the method for obtaining in pure form or as a mixture of the bioactive diol forms of the main secoiridoid phenols present in olive oil and certain isomeric forms or derivatives thereof. Specifically, it relates to the production process of S-(E)-oleocanthadiol, S-(E)-oleaceinediol, 5S-(E)-oleomissionadiol, 5S-(E)-oleokoronadiol, oleuropeinediol and ligstrodiol and their corresponding polyethylene glycol hemiacetals through extraction of specifically selected olive oil with polyethylene glycol and then treated with water. It also relates to the pharmaceutical preparations containing the above substances in various combinations and the therapeutic properties of these preparations for the treatment of cancer, degenerative diseases of the central nervous system, diabetes, hyperlipidemia, inflammatory diseases and the prevention of creation of atherosclerotic plaques and thrombi.

Compositions for increasing corn oil recovery and embodiments of methods for using the composition for corn oil separation are described. The composition(s) incorporate an admixture that includes a polymer selected from a polyglycol ester, a polyethyleneoxide-polypropyleneoxide block copolymer, a poloxamine, or a mixture thereof. The methods include admixing the compositions with a process stream for, for example, the extraction of oil from milled corn and residues from a fermentation step, including stillage (e.g., thin stillage or mid stillage), distiller's wet grain, distiller's dry grain and distiller's dry grains with solubles.

An oil extraction process may be performed on an oleaginous feedstock using an alcohol-based solvent, such as ethanol. In some examples, an extraction process involves conveying a material in countercurrent direction with an alcohol-based solvent to generate an extracted material and a miscella. The miscella stream is cooled (14) to form a first solvent-rich layer phase separated from a first oil-rich layer, which is then separated (18) to form a first separated oil-rich stream (100) and a first separated solvent-rich stream (102). In some examples, the first separated solvent-rich stream is recycled back to the extractor and introduced into the extractor at a location (38) different than a location (30) where fresh solvent is introduced into the extractor. Additionally or alternatively, water (103) may be introduced into the separated first oil-rich stream to form a second solvent-rich layer phase separated from a second oil-rich layer, which is then separated (20) to form a second separated oil-rich stream (104).
