Book excerpt: A method for the hydroconversion of coal by solvent treatment at elevated temperatures and pressure wherein an alcohol having an .alpha.-hydrogen atom, particularly a secondary alcohol such as isopropanol, is utilized as a hydrogen donor solvent. In a particular embodiment, a base capable of providing a catalytically effective amount of the corresponding alcoholate anion under the solvent treatment conditions is added to catalyze the alcohol-coal reaction.

Download or read book Process for Solvent Refining of Coal Using a Denitrogenated and Dephenolated Solvent written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A process is disclosed for the solvent refining of non-anthracitic coal at elevated temperatures and pressure in a hydrogen atmosphere using a hydrocarbon solvent which before being recycled in the solvent refining process is subjected to chemical treatment to extract substantially all nitrogenous and phenolic constituents from the solvent so as to improve the conversion of coal and the production of oil in the solvent refining process. The solvent refining process can be either thermal or catalytic. The extraction of nitrogenous compounds can be performed by acid contact such as hydrogen chloride or fluoride treatment, while phenolic extraction can be performed by caustic contact or contact with a mixture of silica and alumina.

Download or read book Understanding Wyoming Coal Partition During Solvent Extraction and Their Non-thermal Applications written by Ian Hammontree and published by . This book was released on 2020 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of coal as a fuel source has been decreasing rapidly due to economic and environmental concerns. As a result, it is becoming increasingly important to find alternative uses for this abundant resource for states and countries that have economies that rely heavily on coal. Previous work from our group has shown that treatment of coal with various solvents can convert Wyoming coal into carbon fiber mats for non-thermal applications, such as electrodes for energy storage devices (supercapacitors or batteries). However, there still lacks systematic study on the fate of different streams for one of the most cost-effective, environmentally friendly, and biodegradable solvents, formed from choline and l-arginate in water, referred to as [Ch][ARG]. In this work, Wyoming coal from the Powder River Basin was treated with [Ch][ARG], with the coal fragments insoluble in the solvent being referred to as char. The [Ch][ARG] char was carefully characterized and used as precursors for electrospinning. FT-IR and TGA-MS results of the char showed the presence of the [Ch][ARG] used for treatment despite thorough washing and of oxygen containing functional groups. N2 and CO2 physisorption results showed the porosity of the char is located mainly in the sub nanometer region (microporous), with a very low percentage of mesopores (> 2nm). The coal derived carbon fiber mats (CFM) were characterized using FT-IR and scanning electron microscope (SEM) and tested for their potential applications in semipermeable membranes.

This book was released on 2018-05 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Solvent Extract and the Plastic Properties of Coal Because the earlier work had covered studies on only three samples of coal, we decided to extend it to cover more coals of various ranks, volatile matter con tents, and maximum fluidity levels. This report presents the results of these extended studies. In this work emphasis was placed on the relationship of quan tity of extract to maximum fluidity and on the maximum fluidities of blends made by combining extracts and residues in different proportions Chemical analyses for coals, extracts, and residues are presented, and, in addition, molecular weight data are given for the pyridine extracts and fractions thereof derived by further solvent treatment.

This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A preliminary study has been completed for the assessment of solvent extraction for coal gasifier wastewater treatment. This study shows very favorable economics; wastewater contaminants have a market value of about $45.00 per 1000 gallons of water to be treated while treatment costs are about $1.25 to $2.50 per 1000 gallons. Measurements of distribution coefficients between water and various solvents has been completed for m-dihydroxybenzene (resorcinol) and is in progress for o- and p-dihydroxybenzene, pyridine, o-cresol, and naphthol. A very high distribution coefficient of 40 was found for m-dihydroxybenzene between water and octanone-2 (methyl heptyl ketone).
