Paperback. Condizione: New. Print on Demand. Deepen your understanding of coking coal at low temperatures and discover novel applications of the method. This book explores the potential of alternative procedures to traditional high-temperature techniques through a series of compelling and thorough studies. The author examines the properties and composition of the products resulting from coking coal at low temperatures, such as coke, gas, and tar. Learn about the formation of coke and the factors that influence its quality, including the presence of coking substances and the oxygenation of these compounds. Discover insights into the nature of tar produced at low temperatures and its applications in various industries. 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 focuses on the process of carbonizing coal at lower temperatures to produce a different type of fuel by modifying its composition. The author argues that certain degradation products in coal, stemming from its original plant components, form a cement-like binder that is vital in the coking process. These compounds, primarily drawn from plant resins, melt at approximately 300-320°C and, if the powdered coal becomes pasty at this temperature, it is evidence that the coal will coke well. This distinguishes this text from studies primarily focused on the gas and tar produced by coal carbonization. This book's insights on coal's composition and coking utility will prove valuable to coal industry professionals and researchers. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
