ABSTRACT
This chapter discusses the unusual, yet practical, uses of activated carbon that could not be congruously placed. Activated carbon also absorbs microwave radiation and converts it into thermal energy. In effect, activated carbon behaves as a microwave susceptor similar to aluminum encased in current microwave packaging. Microwave susceptors allow food to become browned within a microwave oven as if it were in a convection oven. The use of nonmetals such as activated carbon as a microwave susceptor has attracted researchers. Microwave packaging is composed of heating layers of activated carbon and graphite in a myriad of patterns so as to confer uniform heating in a microwave oven. Solar refrigerators may be fabricated with activated carbon and methanol working medium to produce 4-5 kg ice/day and operate for one week. A numerical simulation of one year of operation in Rabat was used to study the performance of an adsorptive solar refrigerator functioning with activated carbon and methanol.
