Purpose. For use in adsorption heat converters (AHT) for various purposes.
Specifications. The technological process for the production of composite sorbents consists of the following stages: preparation of reagents containing 35 wt.% HCl “high purity”, 98 wt.% H2SO4 “reagent grade”, 25 wt.% NH3 “analytical grade” and 96 wt.% C2H5OH, respectively; grinding of composites; crystallization; obtaining a composite sorbent by precipitation of liquid silicate glass with acetic acid 45 wt. parts, drying and fractionation.
Area of use. Production of other chemical products. Production of non-electrical household devices. Supply of steam, hot water and air conditioning.
Advantages. The use of the developed technology for the synthesis of new composite sorbents based on crystalline hydrates and an organosilicon matrix makes it possible to obtain composites that have a longer service life, since the salt is not washed out from the silica gel pores and its individual structure. In addition, their desorption temperature is below 80°C, which allows the use of alternative energy sources and low-potential energy resources, which will help reduce the operating costs of adsorption heat converters.
Technical and economic effect. The use of the created technology will improve the efficiency of adsorption heat converters for various purposes due to a longer service life of the composite sorbent compared to similar materials and a lower regeneration temperature. This technology uses a low-concentration solution of acetic acid, which makes production cheaper and environmentally friendly. This technology makes it possible to recycle spent or unsuitable for use in APT composite material, increasing the yield of the composite to 50 wt. h., and makes production cheaper by 15-25%.
Description. The developed technology contains one production line using dispensers, a mixing reactor equipped with a heating element, a filter and a fluidized bed dryer.
