Carbon dioxide adsorption in a fixed bed of natural zeolite evolved during composting of agro- industrial waste
Composting is environmental friendly technology for treating and recycling a variety of organic waste, but also releases to the atmosphere, heat, CO2, NH3, water vapour. Carbon dioxide is the main gas generated by the microbial degradation of organic materials during composting. The purpose of this work was to remove carbon dioxide from exhaust gases by sorption on zeolite, clinoptilolite, evolved during composting of agro- industrial waste. The effect of different bed depths of zeolite was investigated. The exhaustion time increased with increase of bed depth. Adsorption capacity of zeolite was determined at room temperature and preassure using data from breakthrough curves of CO2 and was obtained employing the Langmuir and Freundlich isotherms. Langmuir model gives better fit to experimental data than Freundlich model. Maximum adsorption capacitiy for zeolite was 18.20 mg/g. Cumulative evolved mass of CO2 after 21 days of composting was 318.55 g/kgVT and after adsorption on natural zeolite was 229.84 g/kgVT.
