This book was released on 2017-07-30 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three fossil fuels – coal, oil and gas supply over 80% of the global primary energy requirements and, in spite of concerns about environmental pollution, the dominance of fossil fuels in the world’s energy mix is unlikely to change very much in the foreseeable future. Coal, the highest pollutant of them all fuels over 40% of the global electric power generation and, while considerable effort is being made to diversify to less anthropogenic fuels , various projections show that there will be little change for many years. Most of the increase in power generation in the next few decades will be accounted for by emerging countries and, for many, coal is the only available or affordable source of primary energy. Also, some developed countries depend on coal for up to 90% of power generation. The contribution of cleaner energies (solar, wind, biofuels, etc.), to the global primary energy mix is not likely to exceed 10% in the next two or three decades and it is now widely accepted that the only feasible option in the foreseeable future is to ‘clean-up’ coal. For over fifty years Nigeria depended on coal for over 70% of primary energy requirements but, with the discovery of oil and gas in early 1960s the demand for coal began to decline. However, in view of perpetual and intractable problems with gas supply and the hydrodams, there has been renewed interest in the country’s vast coal resources and many coal-fired power plants are scheduled to come on stream by 2020. It is noteworthy that all the proposed plants will adopt clean coal technologies.
Download or read book Spontaneous Combustion of Coal written by Xinyang Wang and published by Springer Nature. This book was released on 2019-11-22 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to understand, analyze and mitigate the harmful impacts of spontaneous coal combustion in underground mines, a thermal phenomenon that triggers fires and explosions threatening the safety of mine workers globally. Based on experimental and theoretical research findings, the book emphasizes three essential questions that are fundamental to understand spontaneous coal combustion: What are the root causes? How to evaluate the causative factors to determine the activity of coal? and How to bring this issue under control in real longwall panel? Readers are introduced to experimental techniques applied to investigate the basic molecular structure of coal and evaluate chemical properties that induce self-heating behavior, theoretical analyses to predict the extrinsic effect on low temperature oxidation of coal in experimental scale and full-size longwall panel, and preventive measures to mitigate this issue using methods for retardant screening, numerical simulations for optimal grouting and nitrogen injections, and case studies analyzing thermal events using mine atmosphere gas monitoring data. The book will be of interest to students and researchers studying mining engineering and chemistry, as well as engineers and practitioners involved in coal mine development and risk assessment.
Download or read book BASIC COAL SCIENCE AND TECHNOLOGY written by Adeniyi A. Afonja and published by ChudacePublishing. This book was released on 2022-06-03 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal has been a major energy source for centuries. In 2021, coal provided around 28% of the total global primary energy requirements and 47% of the electricity demand. Coal also fuels around 80% of the world’s total iron and steel production. In spite of current global efforts to decarbonize the global environment by eliminating coal (the most polluting fossil fuel) all projections indicate that it will remain prominent in the global energy scene in the foreseeable future, filling about 21% of the primary energy demand and providing around 35% of electricity in 2040. Coal is also a precursor to many valuable gaseous and liquid fuels, premium chemicals and high-technology carbon materials. This book serves as an introduction to the extensive science and technology of coal, in particular, the properties which largely determine the utilization potentials of one of the world’s most valuable primary energy resources.

Download or read book Biochar for Environmental Management written by Dr. Johannes Lehmann and published by Earthscan. This book was released on 2009 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.
