Paperback. Condizione: New. Print on Demand. This book delves into the topic of potentially volatile trace elements in coal, presenting a comprehensive study on their occurrence and distribution. The author's research provides valuable insights into the chemical composition of coal and its implications for environmental concerns related to coal combustion. Through meticulous analyses of coal samples, the author determines the concentrations of various trace elements present in both whole coal and coal ash, shedding light on their behavior during combustion processes. This in-depth examination contributes to the understanding of how these elements impact the environment, particularly their potential for atmospheric release. The findings presented in this book serve as a valuable resource for researchers, policymakers, and individuals seeking to mitigate the environmental impact of coal utilization. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Condizione: New. Print on Demand. This book presents detailed findings on the chemical composition of coal, with a particular emphasis on trace elements. The authors analyzed more than 101 coal samples, representing various geological formations and geographical regions. Their work provides valuable insights into the distribution and abundance of elements such as arsenic, cadmium, lead, and selenium in coal. The book also highlights the potential environmental and health implications of these elements, especially when coal is burned for energy production. By examining the occurrence and distribution of trace elements in coal, this book contributes to a better understanding of the environmental and geochemical processes that have shaped coal deposits over time.

Paperback. Condizione: New. Print on Demand. This book delves into the chemical composition of coal, presenting a comprehensive analysis of trace elements found in coal samples from the United States. The author meticulously examines 60 elements, including boron, chlorine, and selenium, which are found in higher concentrations in coal compared to the Earth's crust. By comparing these concentrations to the average elemental composition of the planet, the book uncovers the unique ability of coal to accumulate specific elements during its formation. The author's exploration of the distribution of these elements within coal seams provides valuable insights into the geological processes that shaped coal deposits. This in-depth analysis contributes to our understanding of coal's geochemical properties and its potential environmental implications.
