The book "Study of Micro-porous Characteristics of Activated Carbon" offers a comprehensive analysis of the properties of activated carbon, particularly regarding its microporous structures. Activated carbon, made from mature coconut shells, exhibits outstanding gas adsorption properties that are significant for various applications in refrigeration technology. Authors Subhabrata Das and Gopinath Halder illuminate the challenges and opportunities arising from the use of activated carbon in adsorption refrigeration systems. These systems represent an environmentally friendly alternative to conventional refrigerants, which have harmful effects on the environment. The book is aimed at professionals and students who are engaged with the latest developments in refrigeration technology and the eco-friendly alternatives to traditional refrigerants.
