Chapter 1Introduction Abstract In this chapter, we give a summary for the solid composite sorbents,including the fundamental principle, theory and working pairs of solid sorption,properties of composite sorbents with expanded natural graphite(ENG) matrix, aswell as the energy conversion cycles of solid composite sorbents. Basically,thefeatures and the development of solid composite sorbents are djscussed thoroughly.Keywords Composite sorbent Expanded natural graphite - Working pair Cycle - Energy conversion Sustainable development is the common pursuit of people all over the world, and forwhich the energy utilization is the key factor. The rapid development of economyis usually accompanied by huge energy consumption. as well as the pollution to theenvironment. One important strategy for the sustainable development is to coordinatethe relations among the energy utilization, economy development and environmentalprotection. In terms of environmental protection,the destruction of the ozone layer bychlorofluorocarbons(CFCs) has become a recognized problem all over the world.CFCs are very important substances in compression refrigeration. As an alternativesubstance,HCFCs can only be used temporarily because they also affect the ozonelayer. At the same time, for central heating, the combustion of gas and coal increasescarbon dioxide emissions. As people all over the world demand more and morecomfortable living conditions, the increasingly serious greenhouse effect and ozonelayer depletion have gotten more and more attention. To find a type of green tech-nology for air conditioning, heat pump, energy storage, and electricity generation isvery important for solving the problems caused by the conventional technology.Another key issue for refrigeration and heat pump is the energy utilization.Conventional compression refrigerators and heat pumps are usually driven by elec-tricity. The electricity demand increases fast with the development of the society.According to data provided by the Us Department of Energy,air conditioningaccounts for about 12% of US home energy expenditures in 2018-2019.Meanwhile,the electricity consumption by the airconditioner in China occupies 34%e of the whole world consumption in 2018-2019.The energy efficiency of electricity generation bythermal power plant is only about 40% to 50%, of which a great part of the energyhas been released to the environment as the waste heat with the temperature around70-200 °C. Meanwhile the solar energy and geothermal heat also exist with greatamount in the environment as low-grade energy. The development of refrigeration,heat pump and energy storage technologies driven by low-grade thermal energy suchas factory waste heat, solar energy,and geothermal energy will be a solution for futureenergy conservation. Sorption refrigeration, heat pump, energy storage and water production technolo-gies are driven by low-grade thermal energy and adopt green refrigerants,whichare in harmony with the current energy and environmental sustainability require-ments. First of all, sorption refrigeration technology has very low requirements forelectricity. Secondly, the refrigerants of sorption refrigeration are generally water,ammonia,methanol and other substances,which are green refrigerants with zeroODP(ozone depletion potential) and zero GwP(greenbouse effect potentia]). a kind of sorption technology, the solid sorption has received more and moreattention since the 1970s. Compared with absorption refrigeration technology, thesolid sorption refrigeration has great scopes of sorbents,including different phys-ical and chemical sorbents,which could satisfy the low-grade heat in the range of50-400 °C. Secondly,solid sorption refrigeration does not require solution pumpsand rectification equipments, so there are no refrigerant pollution and solution crys-tallization problems that often occur in absorption refrigeration technology. But ingeneral, the efficiency of solid sorption refrigeration is not as good as absorptionrefrigeration, and the solid sorption bed also has the disadvantage of large size. Solidsorption technology has been recognized as an essential supplementary technologyfor the absorption technology because of these advantages and disadvantages. 1.1Solid Sorption Phenomena According to the different forces for solid sorption processes,the solid sorptionis divided into physical solid sorption and solid chemisorption[1]. The physicalsolid sorption is accomplished by van der Waals forces among the molecules, whichgenerally occur on the surface of the sorbent. The physical solid sorption doesn'thave the selectivity, which means the multi-layer solid sorption can be formed.Thephenomenon of physical solid sorption can be regarded as the condensation processof the refrigerant inside the sorbent. For most sorbents, the heat of solid sorptionis similar to the condensation heat of the refrigerant. The sorbent molecules forthe physical soli
