Book excerpt: With the issuance of this report, all tasks and primary objectives of the contract have been addressed and completed, with the exception of the final report preparation, which is currently on-going. This study has attempted to examine that which complicates all phases of coal utilization, i.e., the contained minerals within the coal and the effect of coal cleaning on their distribution. Three nationally important and regionally different bituminous coals - the Pittsburgh seam, the Pocahontas No. 3 seam, and the Illinois No. 6 seam - have been studied during the course of the work, and a discussion of the final data acquisition, some of the findings, and data revisions are presented in this document. Primary emphasis was on the mineral distributions and their concurrent actions. To study this, mineral washability diagrams, mineral separabilities and other data graphics were prepared to assist in interpreting the relationships. As part of the finalization of data acquisition, a complete petrographic analysis of macerals and submacerals for the Illinois No. 6 coal was also performed. Methods and data presentation used are similar to that previously employed to allow comparisons of these three sets of coal samples.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Unit operation pilot scale tests have been completed for froth flotation, tabling and jigging cleaning operations. An assessment and chemical/mineralogical data for these tests are reported herein. Tests for the heavy media cyclone and WEMCO HMS unit are on-going and will be reported in the next quarter. Also completed during the report period was an in-depth petrographic analysis of the Pocahontas No. 3 coal. Coal macerals by size and gravity were determined as volume percent of the whole coal and are contained in this report. This leaves only the Illinois No. 6 samples for detailed maceral analysis vs. screen/gravity fractions. Accumulation of XRPD data for coal minerals with Pocahontas No. 3 was continued based on the methodology presented in Quarterly Report No. 8. Standardization equations were developed for the Pocahontas No. 3 and Illinois No. 6 samples and mineralogical trends for these coals and the Pittsburgh seam samples were determined. Some generalizations are possible which should aid in interpreting the preparation plant and pilot plant cleaning of these coals. Illite and quartz constitute the majority of all LTA's whether of cleaned coals or refuse. Some minerals display the proprty of being highly separated into either the cleaned coal or the refuse, especially when fine coal sizes are cleaned. Calcite and kaolinite are prime examples in that kaolinite is greatest in the LTA's of the cleaned coal, and calcite is greatest in the LTA's of the refuse. Minerals such as apatite and siderite are most effectively separated into the cleaned coal and refuse only when large coal sizes are cleaned.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: All basic data acquisition relevant to characterization of the contract samples physically and chemically has been completed. Assessment of this data and inter-relationships with mineralogical characterization data is concurrently on-going, with final petrographic data acquisition for the contract to be affected during the next quarter. This remaining analytical work is the detailed maceral analysis of the Illinois No. 6 samples. Work during this quarter focused on coarse and fine coal heavy-media pilot-scale cleaning operations using a heavy-media drum separation and a heavy-media cyclone. Chemical and mineralogical effects produced by these tests are reported herein, completing Task 4 testing of the effects of laboratory pilot cleaning on mineral composition and distribution. Results for froth flotation, size by gravity, jigging, and tabling for this task have been previously reported. Also completed during the work period was the chemical characterization of the Illinois No. 6 slurry-fines sample. Mineralogical data for this sample were reported in Progress Report Number 9.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research program is to examine the effects of coal mineral materials on coal waste by-product utilization and to investigate new and improved methods for the utilization of waste by-products from cleaning, combustion and conversion processing of coal. The intermediate objectives include: (1) the examination of the effects of cleaning, gasification and combustion on coal mineral materials; and (2) the changes which occur in the coal wastes as a result of both form and distribution of mineral materials in feed coals in conjunction with the coal treatment effects resulting from coal cleaning or either gasification or combustion.

Book excerpt: Field samples from the District 7 preparation plant were collected at the plant site in southern West Virginia, and transported to Morgantown for processing. Bulk samples of feed coal, refuse, and clean coal were sampled from hoppers and belt lines, and initial processing prior to characterization was begun. Arrangements to sample an Illinois preparation plant have been completed and this work will be conducted during the fifth quarter. Additional characterization data from the District 3 preparation plant samples are included in this report and the status of the pilot scale preparation plant beneficiation equipment and initial testing is discussed.

Download or read book The Chemistry and Technology of Coal, Third Edition written by James G. Speight and published by CRC Press. This book was released on 2012-09-04 with total page 849 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for coal use (for electricity generation) and coal products, particularly liquid fuels and chemical feedstocks, is increasing throughout the world. Traditional markets such as North America and Europe are experiencing a steady increase in demand whereas emerging Asian markets, such as India and China, are witnessing a rapid surge in demand for clean liquid fuels. A detailed and comprehensive overview of the chemistry and technology of coal in the twenty-first century, The Chemistry and Technology of Coal, Third Edition also covers the relationship of coal industry processes with environmental regulations as well as the effects of combustion products on the atmosphere. Maintaining and enhancing the clarity of presentation that made the previous editions so popular, this book: Examines the effects of combustion products on the atmosphere Details practical elements of coal evaluation procedures Clarifies misconceptions concerning the organic structure of coal Discusses the physical, thermal, electrical, and mechanical properties of coal Analyzes the development and current status of combustion and gasification techniques In addition to two new chapters, Coal Use and the Environment and Coal and Energy Security, much of the material in this edition been rewritten to incorporate the latest developments in the coal industry. Citations from review articles, patents, other books, and technical articles with substantial introductory material are incorporated into the text for further reference. The Chemistry and Technology of Coal, Third Edition maintains its initial premise: to introduce the science of coal, beginning with its formation in the ground to the production of a wide variety of products and petrochemical intermediates in the twenty-first century. The book will prove useful for scientists and engineers already engaged in the coal and/or catalyst manufacturing industry looking for a general overview or update on the clean coal technology as well as professional researchers and students in chemistry and engineering.
