Overview

The Coal Preparation Society of India is a non-profit, non-government professional body whose members come from among the coal, power, iron, and steel sectors and their allied industries. CPSI has dedicatedly promoted the washing of high ash coal to improve it’s quality and enhance it’s calorific value. Such efforts will lead to more environmentally-friendly usage of coal as a source of energy. It will therefore be a step, which will facilitate fulfilling a national commitment within India to decisions taken in COP 21. CPSI is a front runner in the promotion of the use of washed coal in India. This book contains over 100 high quality papers from some 15 countries, covering all aspects of coal processing and also touching upon gasifi cation, coal to chemicals and emerging uses of coal through its conversion into high value, low polluting energy and petro substitutes.
